A free radical gas produced endogenously by a variety of mammalian cells, synthesized from ARGININE by NITRIC OXIDE SYNTHASE. Nitric oxide is one of the ENDOTHELIUM-DEPENDENT RELAXING FACTORS released by the vascular endothelium and mediates VASODILATION. It also inhibits platelet aggregation, induces disaggregation of aggregated platelets, and inhibits platelet adhesion to the vascular endothelium. Nitric oxide activates cytosolic GUANYLATE CYCLASE and thus elevates intracellular levels of CYCLIC GMP.
The worsening of a disease over time. This concept is most often used for chronic and incurable diseases where the stage of the disease is an important determinant of therapy and prognosis.
Splitting of the vessel wall in the VERTEBRAL ARTERY. Interstitial hemorrhage into the media of the vessel wall can lead to occlusion of the vertebral artery, aneurysm formation, or THROMBOEMBOLISM. Vertebral artery dissection is often associated with TRAUMA and injuries to the head-neck region but can occur spontaneously.
Age as a constituent element or influence contributing to the production of a result. It may be applicable to the cause or the effect of a circumstance. It is used with human or animal concepts but should be differentiated from AGING, a physiological process, and TIME FACTORS which refers only to the passage of time.
Disorders of one or more of the twelve cranial nerves. With the exception of the optic and olfactory nerves, this includes disorders of the brain stem nuclei from which the cranial nerves originate or terminate.
An acquired or spontaneous abnormality in which there is communication between CAVERNOUS SINUS, a venous structure, and the CAROTID ARTERIES. It is often associated with HEAD TRAUMA, specifically basilar skull fractures (SKULL FRACTURE, BASILAR). Clinical signs often include VISION DISORDERS and INTRACRANIAL HYPERTENSION.

Criteria and standards used for the determination of the appropriateness of the inclusion of patients with specific conditions in proposed treatment plans and the criteria used for the inclusion of subjects in various clinical trials and other research protocols.
Obstruction of flow in biological or prosthetic vascular grafts.
An abnormal direct communication between an artery and a vein without passing through the CAPILLARIES. An A-V fistula usually leads to the formation of a dilated sac-like connection, arteriovenous aneurysm. The locations and size of the shunts determine the degree of effects on the cardiovascular functions such as BLOOD PRESSURE and HEART RATE.
Studies in which subsets of a defined population are identified. These groups may or may not be exposed to factors hypothesized to influence the probability of the occurrence of a particular disease or other outcome. Cohorts are defined populations which, as a whole, are followed in an attempt to determine distinguishing subgroup characteristics.
The rhythmical expansion and contraction of an ARTERY produced by waves of pressure caused by the ejection of BLOOD from the left ventricle of the HEART as it contracts.
A network of nerve fibers originating in the upper four CERVICAL SPINAL CORD segments. The cervical plexus distributes cutaneous nerves to parts of the neck, shoulders, and back of the head. It also distributes motor fibers to muscles of the cervical SPINAL COLUMN, infrahyoid muscles, and the DIAPHRAGM.

Donor MHC and adhesion molecules in transplant arteriosclerosis. (1/4744)

Transplant-associated arteriosclerosis remains an obstacle to long-term graft survival. To determine the contribution to transplant arteriosclerosis of MHC and adhesion molecules from cells of the donor vasculature, we allografted carotid artery loops from six mutant mouse strains into immunocompetent CBA/CaJ recipients. The donor mice were deficient in either MHC I molecules or MHC II molecules, both MHC I and MHC II molecules, the adhesion molecule P-selectin, intercellular adhesion molecule (ICAM)-1, or both P-selectin and ICAM-1. Donor arteries in which ICAM-1, MHC II, or both MHC I and MHC II were absent showed reductions in neointima formation of 52%, 33%, and 38%, respectively, due primarily to a reduction in smooth muscle cell (SMC) accumulation. In P-selectin-deficient donor arteries, neointima formation did not differ from that in controls. In donor arteries lacking both P-selectin and ICAM-1, the size of the neointima was similar to that in those lacking ICAM-1 alone. In contrast, neointima formation increased by 52% in MHC I-deficient donor arteries. The number of CD4-positive T cells increased by 2.8-fold in MHC I-deficient arteries, and that of alpha-actin-positive SMCs by twofold. These observations indicate that ICAM-1 and MHC II molecules expressed in the donor vessel wall may promote transplant-associated arteriosclerosis. MHC I molecules expressed in the donor may have a protective effect.  (+info)

Anti-monocyte chemoattractant protein-1/monocyte chemotactic and activating factor antibody inhibits neointimal hyperplasia in injured rat carotid arteries. (2/4744)

Monocyte chemoattractant protein-1 (MCP-1)/monocyte chemotactic and activating factor (MCAF) has been suggested to promote atherogenesis. The effects of in vivo neutralization of MCP-1 in a rat model were examined in an effort to clarify the role of MCP-1 in the development of neointimal hyperplasia. Competitive polymerase chain reaction analysis revealed maximum MCP-1 mRNA expression at 4 hours after carotid arterial injury. Increased immunoreactivities of MCP-1 were also detected at 2 and 8 hours after injury. Either anti-MCP-1 antibody or nonimmunized goat IgG (10 mg/kg) was then administered every 12 hours to rats that had undergone carotid arterial injury. Treatment with 3 consecutive doses of anti-MCP-1 antibody within 24 hours (experiment 1) and every 12 hours for 5 days (experiment 2) significantly inhibited neointimal hyperplasia at day 14, resulting in a 27.8% reduction of the mean intima/media ratio (P<0.05) in experiment 1 and a 43.6% reduction (P<0.01) in experiment 2. This effect was still apparent at day 56 (55.6% inhibition; P<0.05). The number of vascular smooth muscle cells in the neointima at day 4 was significantly reduced by anti-MCP-1 treatment, demonstrating the important role of MCP-1 in early neointimal lesion formation. However, recombinant MCP-1 did not stimulate chemotaxis of vascular smooth muscle cells in an in vitro migration assay. These results suggest that MCP-1 promotes neointimal hyperplasia in early neointimal lesion formation and that neutralization of MCP-1 before, and immediately after, arterial injury may be effective in preventing restenosis after angioplasty. Further studies are needed to clarify the mechanism underlying the promotion of neointimal hyperplasia by MCP-1.  (+info)

Vascular remodeling in response to altered blood flow is mediated by fibroblast growth factor-2. (3/4744)

Vascular structures adapt to changes in blood flow by adjusting their diameter accordingly. The factors mediating this process are only beginning to be identified. We have recently established a mouse model of arterial remodeling in which flow in the common carotid artery is interrupted by ligation of the vessel near the carotid bifurcation, resulting in a dramatic reduction in vessel diameter as a consequence of inward remodeling and intimal lesion formation. In the present study, we used this model to determine the role of fibroblast growth factor-2 (FGF-2) in the remodeling response by maintaining neutralizing serum levels of a mouse monoclonal antibody against FGF-2 for 4 weeks. Morphometric analysis revealed that intimal lesion formation was not affected by the antibody. However, lumen narrowing was significantly inhibited, resulting in a greater than 3-fold increase in lumen area in anti-FGF-2-treated animals compared with controls. Treatment with anti-FGF-2 antibody significantly inhibited the reduction in vessel diameter (inward remodeling) and shortening of the internal elastic lamina in the ligated vessel. In addition, anti-FGF-2 treatment also caused outward remodeling of the contralateral carotid artery. These findings identify FGF-2 as an important factor in vascular remodeling, and its effects are likely to be mediated by increasing vascular tone. The results are consistent with the recent observation of reduced vascular tone in the FGF-2-deficient mouse.  (+info)

Expression and cellular localization of the CC chemokines PARC and ELC in human atherosclerotic plaques. (4/4744)

Local immune responses are thought to play an important role in the development of atherosclerosis. Histological studies have shown that human atherosclerotic lesions contain T lymphocytes throughout all stages of development, many of which are in an activated state. A number of novel CC chemokines have been described recently, which are potent chemoattractants for lymphocytes: PARC (pulmonary and activation-regulated chemokine), ELC (EBI1-ligand chemokine), LARC (liver and activation-regulated chemokine), and SLC (secondary lymphoid-tissue chemokine). Using reverse transcriptase-polymerase chain reaction and in situ hybridization, we have found gene expression for PARC and ELC but not for LARC or SLC in human atherosclerotic plaques. Immunohistochemical staining of serial plaque sections with specific cell markers revealed highly different expression patterns of PARC and ELC. PARC mRNA was restricted to CD68+ macrophages (n = 14 of 18), whereas ELC mRNA was widely expressed by macrophages and intimal smooth muscle cells (SMC) in nearly all of the lesions examined (n = 12 of 14). ELC mRNA was also found to be expressed in the medial SMC wall of highly calcified plaques (n = 4). Very low levels of ELC mRNA expression could also be detected in normal mammary arteries but no mRNA expression for PARC was detected in these vessels (n = 4). In vitro, ELC mRNA was found to be up-regulated in aortic SMC stimulated with tumor necrosis factor-a and interferon-gamma but not in SMC stimulated with serum. Both PARC and ELC mRNA were expressed by monocyte-derived macrophages but not monocytes. The expression patterns of PARC and ELC mRNA in human atherosclerotic lesions suggest a potential role for these two recently described CC chemokines in attracting T lymphocytes into atherosclerotic lesions.  (+info)

Variations in acute multifocal histoplasmic choroiditis in the primate. (5/4744)

Experimental histoplasmic choroiditis was produced in primates by intracarotid injections of living H. capsulatum organisms. The severity of the choroiditis varied with inoculum size, as well as with site of injection (common carotid vs. internal carotid artery). A reproducible model of histoplasmic choroiditis in primates was produced with an internal carotid injection of 5,000 to 10,000 organisms/lb. The clinical and histopathological course of this acute choroiditis over the first 30 days is presented.  (+info)

3D angiography. Clinical interest. First applications in interventional neuroradiology. (6/4744)

3D angiography is a true technical revolution that allows improvement in the quality and safety of diagnostic and endovascular treatment procedures. 3D angiography images are obtained by reconstruction of a rotational angiography acquisition done on a C-arm (GE Medical Systems) spinning at 40 degrees per second. The carotid or vertebral selective injection of a total of 15 ml of non-ionic contrast media at 3 ml/sec over 5 seconds allows the selection of the "arterial phase". Four hundred sixty 3D angiographic studies were performed from December 1996 to September 1998 on 260 patients and have been analyzed in MIP (Maximum Intensity Projection) and SSD (Shaded Surface Display) views. The exploration of intracranial aneurysms is simplified and only requires, for each vascular axis, a biplane PA and Lateral run followed by a single rotational angiography run. The 3D angiography image is available on the workstation's screen (Advantage Workstation 3.1, GE Medical Systems) in less than 10 minutes after the acquisition of the rotational run. It therefore allows one to analyze, during the intervention, the aneurysm's angioarchitecture, in particular the neck, and select the best therapeutic technique. When endovascular treatment is the best indication, 3D angiography allows one to define the optimal angle of view and accurately select the microcoils dimensions. 3D angiography replaces the multiple oblique views that used to be required to analyze the complex aneurysms and therefore allows a reduction of the total contrast medium quantity, the patient X-ray dose and the length of the intervention time which is a safety factor. Also, in particular for complex cases, it brings additional elements complementing the results of standard 2D DSA and rotational angiograms. In the cervical vascular pathology, 3D angiography allows for a better assessment of the stenosis level and of dissection lesions. Our current research activities focus on the matching without stereotactic frame between 3D X-ray angiography and volumetric MR acquisition, which should allow us to improve the treatment of intracerebral arterio-venous malformations (AVMs).  (+info)

Expression of stromelysin-3 in atherosclerotic lesions: regulation via CD40-CD40 ligand signaling in vitro and in vivo. (7/4744)

Stromelysin-3 is an unusual matrix metalloproteinase, being released in the active rather than zymogen form and having a distinct substrate specificity, targeting serine proteinase inhibitors (serpins), which regulate cellular functions involved in atherosclerosis. We report here that human atherosclerotic plaques (n = 7) express stromelysin-3 in situ, whereas fatty streaks (n = 5) and normal arterial specimens (n = 5) contain little or no stromelysin-3. Stromelysin-3 mRNA and protein colocalized with endothelial cells, smooth muscle cells, and macrophages within the lesion. In vitro, usual inducers of matrix metalloproteinases such as interleukin-1, interferon-gamma, or tumor necrosis factor alpha did not augment stromelysin-3 in vascular wall cells. However, T cell-derived as well as recombinant CD40 ligand (CD40L, CD154), an inflammatory mediator recently localized in atheroma, induced de novo synthesis of stromelysin-3. In addition, stromelysin-3 mRNA and protein colocalized with CD40L and CD40 within atheroma. In accordance with the in situ and in vitro data obtained with human material, interruption of the CD40-CD40L signaling pathway in low density lipoprotein receptor-deficient hyperlipidemic mice substantially decreased expression of the enzyme within atherosclerotic plaques. These observations establish the expression of the unusual matrix metalloproteinase stromelysin-3 in human atherosclerotic lesions and implicate CD40-CD40L signaling in its regulation, thus providing a possible new pathway that triggers complications within atherosclerotic lesions.  (+info)

Accelerated intimal hyperplasia and increased endogenous inhibitors for NO synthesis in rabbits with alloxan-induced hyperglycaemia. (8/4744)

1. We examined whether endogenous inhibitors of NO synthesis are involved in the augmentation of intimal hyperplasia in rabbits with hyperglycaemia induced by alloxan. 2. Four weeks after the endothelial denudation of carotid artery which had been performed 12 weeks after alloxan, the intimal hyperplasia was greatly augmented with hyperglycaemia. The degree of hyperplasia was assessed using three different parameters of histopathological findings as well as changes in luminal area and intima: media ratio. 3. There were positive and significant correlations between intima:media ratio, plasma glucose, and concentrations of N(G)-monomethyl-L-arginine (L-NMMA) and N(G), N(G)-dimethyl-L-arginine (ADMA) in endothelial cells, that is, the intima:media ratio became greater as plasma glucose and endothelial L-NMMA and ADMA were increased. Furthermore, endothelial L-NMMA and ADMA were increased in proportion to the increase in plasma glucose. 4. In contrast, there were inverse and significant correlations between cyclic GMP production by carotid artery strips with endothelium and plasma glucose, between cyclic GMP production and endothelial L-NMMA and ADMA, and between the intima:media ratio and cyclic GMP production. 5. Exogenously applied L-NMMA and ADMA inhibited cyclic GMP production in a concentration-dependent manner. IC50 values were determined to be 12.1 microM for the former and 26.2 microM for the latter. The cyclic GMP production was abolished after the deliberate removal of endothelium from the artery strips. 6. These results suggest that the augmentation of intimal hyperplasia with hyperglycaemia is closely related to increased accumulation of L-NMMA and ADMA with hyperglycaemia, which would result in an accelerated reduction in NO production/release by endothelial cells.  (+info)

ISSN 2078-5135.. BACKGROUND: Atherosclerosis that starts in childhood invariably advances during adulthood. AIM: We aimed to study the effect of obesity on main carotid artery intima-media thickness (CIMT) and arterial stiffness. MATERIAL AND METHODS: A total of 78 children were studied from October 2010 to February 2011. They were divided into obese (n=42, group 1) and normal (n=36, group 2). All children were subjected to physical examination, routine biochemical and haematological analysis, carotid ultrasonography and echocardiographic measurements. A detailed medical history was obtained. Body mass index (BMI) was calculated by dividing participants weight in kilograms by the square of their height in metres. Stiffness index β was calculated using blood pressure and diameter of the systolic and diastolic ...
Experiments in tissue culture using hydroxamic and phosphinic acid-based inhibitors show that MMPs are necessary for both maximal proliferation and migration of rabbit aortic SMCs.11 Furthermore, MMP inhibitors also prevent intimal migration of rat carotid artery SMCs after balloon injury in vivo.13 In rabbit SMCs, only gelatinases A and B are expressed in measurable quantities,11 which emphasize their role in modulating migration and proliferation in this model, which contains only SMCs. In the rat carotid artery, injury increases tissue levels of gelatinase B and activates gelatinase A,13 19 further implicating gelatinases in the response to injury. In the present study, we also investigated the expression of gelatinases after balloon injury, but in this case, a pig carotid artery model in which both deep medial tears and stretch-induced injury occur was used. Both types of injury are thought to be important in angioplasty restenosis in humans.34 Furthermore, we sought to investigate whether ...
TY - JOUR. T1 - Differential transmural constrictor response to norepinephrine in rabbit carotid artery. AU - Flaim, Stephen F.. AU - Field, John M.. AU - Zelis, Robert. N1 - Funding Information: It has been shown that the vasoconstrictor response of smooth muscle to alpha adrenergic stimulation varies according to the position of the muscle cell within the tunica media of the vessel wall from rabbit thoracic aorta (Pascual et al., 1979), sheep carotid artery (Keatinge et al., 1976) and rabbit ear artery (McCalden et al., 1979). The purpose of the present study was to determine if this phenomenon occurred in the rabbit carotid artery as well as to attempt to further characterize the mechanism of this response. In order to achieve these goals, the response of intact isolated perfused segments of rabbit carotid artery was measured during norepinephrine stimulation applied to either the luminal or the adventitial surface or to both surfaces simultaneously under varying experimental conditions. The ...
The purpose of the study is to investigate the hemodynamic effect of calcified carotid plaque on blood flow in patients diagnosed with carotid artery disease. Two carotid artery models were generated based on a sample patient data, with normal and calcified carotid artery appearances. Circular calcified carotid plaque was found at the carotid bifurcation based on 3D computed tomography images. A computational fluid dynamics was performed to analyze the changes of blood flow in different situations. Our results showed that apparent turbulence was found in the diastolic phase at the carotid bifurcation in normal carotid artery geometry. In the presence of the calcified plaque, the flow velocity was increased to some extent, indicating the effect of plaque on hemodynamic changes. Wall shear stress was noticed to decrease at the aortic branches, and this indicates the potential risk of developing stenosis at this area. Our preliminary study demonstrates fluid structure interaction between calcified ...
Have you been told you have diseased or clogged carotid arteries (carotid stenosis)? Are you nervous about what this may mean in terms of your risk of stroke? Here are some answers to commonly asked questions regarding carotid artery disease.. What are the carotid arteries?. Carotid arteries are the two main blood vessels that supply most of your brain with blood.. What is a carotid bruit and does it definitely mean that the carotid is blocked?. A carotid bruit is a swooshing sound heard during a physical exam in which the physician listens to the sound of blood flow through the neck. When blood passes through a narrowing channel, it will give a very distinctive sound when heard through a stethoscope. Approximately 30 percent of patients with a carotid bruit will have a significant carotid blockage. However, carotid bruits are often associated with the presence of other atherosclerotic heart disease as well as other cardiovascular problems.. How is a carotid bruit assessed by my ...
Introduction and objectives The equations used in the general population to calculate cardiovascular risk are not useful in genetic hypercholesterolemia (GH). Carotid plaque detection has proved useful in cardiovascular prediction and risk reclassification but there have been no studies of its usefulness in GH. The aim of this study was to determine the association between the presence of carotid artery plaque and the occurrence of cardiovascular events in patients with GH.. Methods This study included 1778 persons with GH. The mean follow-up until the occurrence of cardiovascular events was 6.26 years. At presentation, the presence of carotid artery plaque was studied by high-resolution ultrasound.. Results Carotid artery plaque was found in 661 (37.2%) patients: 31.9% with familial hypercholesterolemia, 39.8% with familial combined hyperlipidemia, 45.5% with dysbetalipoproteinemia, and 43.2% with polygenic hypercholesterolemia. During follow-up, 58 patients had a cardiovascular event. Event ...
Lefferts, W., Augustine, J., Heffernan, K., Department of Exercise Science, Syracuse University, Syracuse, NY Cross-sectional studies have identified arterial stiffness as an important correlate of cerebral blood flow (CBF) pulsatility, an important predictor of cerebrovascular damage. Central artery stiffness increases acutely following a bout of resistance exercise (RE). It has yet to be elucidated whether RE-induced increases in arterial stiffness affect CBF pulsatility. Purpose: To investigate the effects of acute RE on carotid artery stiffness and CBF pulsatility. Methods: 18 healthy men (age 22 ± 1 yr; BMI 23.7 ± 0.5 kg∙m-2) underwent a) acute RE (5 sets, 5-RM bench press, 5 sets 10-RM bicep curls with 90 s rest intervals), and b) a time control condition (seated rest) in a randomized order. CBF pulsatility index (PI) was measured with transcranial Doppler at the middle cerebral artery (MCA). Common carotid artery (CCA) beta stiffness (β) and blood flow velocity PI were assessed using Doppler
When narrowing occurs in the main arteries that flow to the brain, the condition is called carotid artery disease. This can increase a persons risk of having a stroke, however, most people are unaware that they might have it!. Carotid duplex ultrasound, or an ultrasound of the carotid artery, is a simple and painless test performed in our office that easily detects carotid artery disease.. Treating carotid artery disease is focused on preventing a stroke, or if you have had a stroke, preventing any further strokes. Lifestyle changes are key in this battle. Sometimes medications are needed as well. Surgeries or stenting may be needed in certain people.. Carotid stenting is a minimally invasive procedure for certain appropriate people with carotid disease. A small metal mesh tube, or stent, is placed in the artery to prop it open.. Discuss with one of our cardiologists to see if you are at risk for carotid artery disease.. ...
Childhood obesity is a major health problem throughout the world. Obese children are more likely to become obese adults in whom one can expect a higher rate of hospitalisation, interventions and premature death.1 In obese people, coronary heart disease generally manifests in middle age or later life. However, atherosclerosis has its roots in childhood, its first signs in obese children appearing before puberty; therefore, it is important to develop efficient strategies to reduce the incidence of cardiovascular disease (CVD) in the population. Carotid artery intima-media thickness (CIMT) serves as a marker of preclinical atherosclerosis.2. CVD develops as a result of arterial damage in the form of arteriosclerosis. Arteriosclerosis is a general term for conditions in which diffuse thickening and stiffening in mainly large- and medium-sized arteries develop under different conditions. Both the media and intima of the arteries could be involved in the pathology. Risk factors diagnosed in childhood ...
OBJECTIVE: The purpose of this study was to examine the association between adiposity measures, ultrasound image quality, and preclinical markers of atherosclerosis in young adults. METHODS: B-mode ultrasound was used to obtain common carotid intima-media thickness and common carotid artery distensibility of 2265 and 1313 adults aged 24 to 39 years in two population-based studies: the Cardiovascular Risk in Young Finns and Childhood Determinants of Adult Health studies. Qualitative assessments of ultrasound image quality were obtained from each study (scored as 1, excellent; 2, average; and 3, poor) based on the ability to detect arterial interfaces and the amount of noise present in the image. RESULTS: Increased adiposity was associated with significantly increased odds (all P | .05) of average or poor carotid ultrasound image quality. Reduced image quality was associated with lower intima-media thickness in Young Finns (regression coefficient = -0.029; P = .01) and higher intima-media thickness in
Carotid artery - What are the carotid arteries? Carotic Arteries. The human carotid arteries supply the head and the neck with oxygenated blood. The left common carotid artery originates from the aorta and the right common carotid originates from the brachiocephalic artery which originates from the aorta. The carotic artery divides in the neck to form the internal and external carotic arteries.

The presence of ulceration in carotid artery plaque is an independent risk factor for thromboembolic stroke. However, the associated pathophysiological mechanisms - in particular the mechanisms related to the local hemodynamics in the carotid artery bifurcation - are not well understood. We investigated the effect of carotid plaque ulceration on the local time-varying three-dimensional flow field using computational fluid dynamics (CFD) models of a stenosed carotid bifurcation geometry, with and without the presence of ulceration. CFD analysis of each model was performed with a spatial finite element discretization of over 150,000 quadratic tetrahedral elements and a temporal discretization of 4800 timesteps per cardiac cycle, to adequately resolve the flow field and pulsatile flow, respectively. Pulsatile flow simulations were iterated for five cardiac cycles to allow for cycle-to-cycle analysis following the damping of initial transients in the solution. Comparison between models revealed ...
Keywords: genetics, carotid artery, ultrasonography, linkage evaluation, variance components Launch Studies show that carotid artery framework and function arent only inspired by coronary disease (CVD) risk elements but also Apremilast may represent phenotypic procedures of vascular disease beyond those conferred by typical CVD risk elements (1C4). Furthermore, latest research have TM4SF4 provided proof a link between carotid artery lumen size and threat of aortic aneurysm development in population-based examples (5C6). In the Troms? Research, investigators discovered that common carotid artery lumen size was independently connected with threat of abdominal aortic aneurysm in guys (odds proportion, OR=1.9 [95% confidence interval, CI: 1.2C2.9]) and females (OR=4.1 [95% CI: 1.5C10.8]), suggesting a link Apremilast between carotid artery dilatation and an over-all arterial dilating diathesis (5).

Increased arterial stiffness assessed by increase PWV and increased pulse pressure have been shown to relate directly with cardiovascular events.23,24 Similar prognostic information can be gained from BRS evaluation in different patient populations at risk for cardiovascular complications. Previous investigations have demonstrated that BRS is significantly related to carotid artery distensibility. A positive association between the elastic properties of the carotid artery and BRS has been reported in healthy volunteers,25 pregnant women,26 hypertensive subjects,27 and nondiabetic patients with carotid artery stenosis.28 However, in this study we did not observe any correlation between BRS and common carotid artery wall distensibility in T2DM patients with at least 2 additional cardiovascular risk factors.. This T2DM population differs significantly from previously published works. We have selected high-risk subjects with T2DM who are characterized by stiffened and diseased arteries as evidenced ...
Carotid artery morphological changes relate to the risk and presence of CAD in patients with suspected CAD. Additionally, the association of carotid artery morphological changes such as carotid artery plaque formation1,2 or stenosis3,4 with the extent of CAD has been reported. Although our observations are consistent with these studies, the study population was limited to patients with CAD with preserved LV function and did not include patients without CAD. In addition to the previous studies, we have shown that even in this selected population, carotid morphological changes are still useful and independent predictors of the extent of CAD and multivessel CAD.. A direct association between functional changes of artery and coronary atherosclerosis has been reported in previous studies.5,6 However, these studies concluded that this association was stronger for aortic stiffness than carotid arterial stiffness, suggesting that in the larger artery, stiffness could be a significant marker of the ...
To our knowledge, this is the first study to examine the accuracy with which central aortic systolic pressure can be estimated noninvasively in children. The method that we elected to compare invasive measures, carotid wall tracking, assumes carotid wall distension to be proportional to local intra-arterial carotid pressure and for carotid pressure to approximate aortic root pressure.15,16 Theoretically, tonometric measurements obtained at the carotid artery would be expected to perform as well as carotid wall tracking.10 However, in preliminary studies, we found that high-quality carotid tonometric recordings were more difficult to obtain than ultrasound wall tracking in children. We compared agreement between cSBP estimated from carotid wall tracking with measured cSBP in a heterogenous group of children in whom central hemodynamics would be expected to vary widely. Despite this, we observed good agreement between estimated and measured central aortic systolic pressures. This suggests that, in ...
One disclosed embodiment comprises a method for treating lesions in the carotid artery of a mammalian body. The method comprises transcervical access and blocking of blood flow through the common carotid artery (with or without blocking of blood flow through the external carotid artery), shunting blood from the internal carotid artery and treating the lesion in the carotid artery.
Carotid artery stiffness, intima-media thickness and early plaque formation are useful predictors of the risk of both ischaemic stroke and coronary heart disease in asymptomatic populations. Early carotid arterial wall disease also predicts coronary artery disease on angiography and subsequent coronary vascular events in populations at risk of coronary heart disease. Carotid stenosis and plaque surface morphology predict both ischaemic stroke and coronary vascular events. © 2004, Elsevier Science B.V. All rights reserved.
Introduction - Arterial stiffness is a major contributor to aging-related cardiovascular diseases. Pericardial fat (Pfat) may have a pathological effect due to its close proximity to the coronary arteries. However, no studies have examined whether Pfat is related to arterial stiffness.. Purpose - We examined the association between baseline measures of Pfat and carotid stiffness in 5768 participants (mean age, 62 yrs; 53% female; 39% Caucasian, 13% Chinese, 25% African American, and 23% Hispanic) from the Multi-Ethnic Study of Atherosclerosis, a prospective cohort study of 45- 84 yr-old men and women free of cardiovascular disease at baseline.. Methods - Pfat volume was assessed by computed tomography. Ultrasonography of the common carotid artery was used to calculate the distensibility coefficient (DC, a measure of compliance) and Youngs modulus (YM, a measure of stiffness). A lower DC and a higher YM are indicative of stiffer arteries. Multiple linear regression was used to determine the ...
New research from the Netherlands shows that older patients with chronic obstructive pulmonary disease (COPD) are at increased risk for carotid artery plaque formation and for the presence of vulnerable plaques with a lipid core, according to the American Thoracic Society. The cross-sectional study, part of the Rotterdam Study, an ongoing population-based cohort study examining the occurrence of and risk factors for chronic diseases in subjects aged 55 years and older, involved 253 patients with COPD and 920 patients without the condition. COPD was confirmed by spirometry. Participations with carotid wall thickening (intima-media thickness ≥ 2.5 mm) on ultrasonography underwent high-resolution MRI to characterize carotid plaques.. Participants with COPD had a twofold increased risk of carotid wall thickening on ultrasonography compared with controls. This risk increased significantly with the severity of airflow limitation. On MRI, vulnerable lipid core plaques were significantly more frequent ...

misc{3051799, abstract = {Cardiovascular diseases, such as atherosclerosis, is a major cause of mortality in, primarily, the western world. To be able to recognize early symptoms of this type of diseases it has proven to be important to investigate the mechanical properties of blood vessels. A few years back from now it became evident that the common carotid artery has a distinct bidirectional movement pattern in the longitudinal direction during each cardiac cycle. The mechanisms of this behavior has however since then been undetermined. In this study three independent indicators of the cardiac wall movements involvement is presented. By ultrasound examinations of both the right and left side common carotids and simultaneous examinations of left ventricle movement of the heart of 14 humans it has become evident that: The longitudinal movement in the carotid arterial wall, in both directions, occurs in parts of the vessel close to the heart before it is transmitted to more peripheral parts of ...
Ultrasound study to assess Carotid Intima Media Thickness in an office setting 525 patients to be enrolled at seven medical centers DALLAS - November 13, 2005 - SonoSite, Inc. (NASDAQ: SONO), the world leader in hand-carried ultrasound, announced today at the 2005 American Heart Association (AHA) Scientific Sessions that it is initiating a multi-center study to determine whether the addition of an ultrasound examination evaluating carotid artery wall thickness (CIMT), performed in the office setting, will provide a more effective tool for risk assessment and prevention of cardiovascular disease than current clinical methods alone. Over 20 years of clinical research has shown that the thickness (T) of the two innermost layers of the carotid artery wall, the intima (I) and media (M), begins to increase before plaque is evident within the vessel. This increased wall thickness is associated with an increased risk of cardiovascular disease, the leading cause of mortality and disability in the United States
Disease of the carotid artery is related to, in large part, the amount of atherosclerosis (or plaque) that is present in one of the main arteries to the brain-the Internal Carotid Artery (ICA. )Typically, the more plaque that is present, the narrower the diameter of the internal portion of the artery is that is delivering blood to the brain. One potential cause of stroke is the lack of enough blood flow to the brain that may be reduced as the inner diameter of the ICA get smaller. Alternatively, a piece of the plaque in the ICA could break away and travel to the brain lodging in a small artery producing a stroke by restricting blood flow (and oxygen) to a particular area of the brain.. While degree of narrowing within the carotid artery is a factor in determining whether intervention is required, the presence of symptoms related specifically to the carotid artery in question is another important factor to be considered. People may have a significant degree of narrowing of their ICA-in fact, it ...

This study aimed to examine the effect of rapamycin on the expression of KLF4 and the role of KLF4 in arterial neointimal formation. EXPERIMENTAL APPROACH Expression of KLF4 was monitored using real-time PCR and immunoblotting in cultured vascular smooth muscle cells. and in rat carotid arteries in vivo after balloon injury. Adenovirus-mediated overexpression and siRNA-mediated knockdown of KLF4 were used to examine the role of KLF4 in mediating the ...
The introduction of cerebral angiography in the 1930s by Moniz, followed by detailed postmortem studies of the cervical portion of the carotid artery in the 1950s by Miller Fisher, drew attention to the extracranial carotid arterys being more important than the middle cerebral artery in ischemic stroke (1). The description of the diagnostic features of carotid disease soon followed, and this led to strategies for preventing or eliminating carotid lesions. From the earliest writings, clinical investigators have debated a possible connection between severe carotid disease and impaired cognition. Few dispute the relationship between cognitive decline and large areas of infarction of cortex supplied by the carotid artery. The unsettled component is the causal relationship between mild cognitive decline and asymptomatic disease in the carotid artery that supplies the dominant hemisphere (the left carotid in 98% of right-handed individuals). In the presence of intellectual changes, should an ...
Introduction: It is unknown whether stroke risk is increased in the setting of large-artery atherosclerotic plaque that does not cause significant luminal stenosis.. Hypothesis: We hypothesized that the prevalence of vulnerable, non-stenosing carotid artery plaque on the side ipsilateral to an acute brain infarction would be higher than on the contralateral side.. Methods: Using a prospective stroke registry, we identified patients with acute infarction limited to the vascular territory of one internal carotid artery (ICA) and no large-vessel atherosclerosis based on the common criterion of greater than or equal to 50% luminal stenosis. We used magnetic resonance angiography to ascertain vulnerable ICA plaque, as defined by the presence of intraplaque high-intensity signal (IHIS). We used McNemars test for correlated proportions to compare the prevalence of IHIS on the side ipsilateral to acute infarction versus the contralateral side within individual subjects.. Results: We analyzed 218 ...

AU - Pattichis, Marios. AU - Barriga, E. Simon. PY - 2012. Y1 - 2012. N2 - An estimated 82 million American adults have one or more type of cardiovascular diseases (CVD). CVD is the leading cause of death (1 of every 3 deaths) in the United States. When considered separately from other CVDs, stroke ranks third among all causes of death behind diseases of the heart and cancer. Stroke accounts for 1 out of every 18 deaths and is the leading cause of serious long-term disability in the United States. Motion estimation of ultrasound videos (US) of carotid artery (CA) plaques provides important information regarding plaque deformation that should be considered for distinguishing between symptomatic and asymptomatic plaques. In this paper, we present the development of verifiable methods for the estimation of plaque ...
In the normal vascular system, the extracellular matrix (ECM), a complex network of various proteins and proteoglycans, is maintained by an intricate balance between synthesis and degradation of its structural components. Maintenance of tissue integrity during normal development and growth is achieved by programmed remodeling of the matrix, involving numerous enzymes as well as specific inhibitors that keep their activity in check. The MMPs are a family of at least 12 zinc-dependent endoproteinases that function at neutral pH and cooperatively hydrolyze most of the proteins in the ECM. In this study, the temporal expression and activity of members of the MMP family and one specific inhibitor, TIMP-1, have been examined using the balloon catheter-induced injury model in the rat carotid artery.. Unlike in the human, there are no smooth muscle cells (SMCs) in the intima of a normal rat carotid artery.19,20 SMCs resident in the media are surrounded by a basal lamina and anchored to the ECM. After ...
Noninvasive imaging of carotid artery plaque with MRI can accurately predict future cardiovascular events like strokes and heart attacks in people without a history of cardiovascular disease, according to a new study published online in the journal Radiology.. Researchers have long known that some arterial plaque is more dangerous because of its vulnerability to rupture. MRI can discern features of vulnerable plaque, such as a lipid core with a thin fibrous cap. This ability makes MRI a potentially valuable tool for identifying patients at risk for subsequent cardiovascular events.. To study the predictive value of MRI plaque imaging, researchers performed carotid artery ultrasound and MRI on 946 asymptomatic patients from the Multi-Ethnic Study of Atherosclerosis (MESA). The carotid arteries are the large vessels located on each side of the neck that carry oxygenated blood to the front part of the brain. They are highly accessible for imaging, and their condition tends to mirror that of the ...
This 3D stock medical animation shows the progression of a left carotid artery occlusion which results in a cerebral infarct (stroke). The animation opens with a generic (blue) figure with the brain and major arteries shown. The camera then zooms into a detailed cut-section through the left carotid artery bifurcation. As blood flows to the brain, an occlusion forms cutting off the circulation resulting in the subsequent death of the brain tissue.
Figure 1 Intraluminal Thrombus. Right carotid angiogram just prior to carotid artery stenting (CAS) showed severe stenosis (arrow) of the internal carotid artery (A). Cross sections by optical coherence tomography (OCT) (B) demonstrated large thrombus as a backscattering protrusion into the carotid lumen with signal free shadowing (white arrow). Intravascular ultrasound (IVUS) (C) showed eccentric and low-echoic plaque, but did not discriminate this thrombus from other tissue components. T1 weighted images of black-blood magnetic resonance imaging (MRI) (D) showed severe stenosis with high intensity spot without clear margin (blue arrow). In this patient, carotid endarterectomy was performed instead of CAS because a large intraluminal thrombus was clearly demonstrated by an OCT. Post-operative pathological analysis with Hematoxylin and Eosin staining (E) demonstrated a large intraluminal red thrombus (blue arrow) in the carotid artery. The bar (B, C, D, and E) equals 2 mm. This patient was ...
Patients will be chosen for the study based on presence of carotid artery stenosis ascertained by CTA and carotid artery ultrasound. Patients will receive and intravenous injection of the radiolabeled PET tracer,[F-18]RGD-K5, and will undergo PET imaging of their carotid arteries bilaterally. PET images will be analyzed to determine the standard uptake value (SUV) of [F-18]RGD-K5 uptake by the carotid artery plaque and this will be compared to the SUV of the background (blood pool in the aorta). This will be expressed as a target to background ratio (TBR). Investigators expect to find a significant uptake of [F-18]RGD-K5 by carotid artery palque and investigators therefore expect to find a TBR that is significantly ,1. Investigators also expect to find that plaque from patients who show a TBR ,1 will also be enriched for histologic markers for inflammation and angiogenesis ...
Carotid artery disease occurs when plaque, a build-up of fat, cholesterol and other substances, collects and forms along the walls of the carotid arteries. This buildup of plaque and the injury it causes is called atherosclerosis.. Over time, the walls of affected arteries thicken and become stiff and the blood vessel may also become narrowed, a condition called stenosis, limiting blood flow.. Left untreated, carotid artery disease increases the risk for stroke. A stroke occurs when blood flow to the brain is obstructed by plaque or blood clots, when bits of plaque break free and travel to smaller arteries in the brain, or when a blood vessel in the brain ruptures. A lack of oxygen and other essential nutrients may cause permanent damage to the brain or death.. ...

N2 - Ultrasound is known to produce a range of nonlethal responses in cells and tissues. Frequencies in the kilohertz ultrasound range have been shown to produce relaxation in large arteries. The present work explores the effects of insonation at MHz frequencies, representative of those used diagnostically and therapeutically, in an in vitro preparation of the carotid artery. Fresh 12.7 mm wide rings of equine common carotid artery obtained from the abattoir were mounted in a purpose-made myograph. They were immersed in a bath of Krebs-Ringer buffer at 37 degrees C and were positioned at the focus of an ultrasound beam from a weakly focused 3.2 MHz source. Continuous wave insonation produced contraction. The tension increased rapidly over the first 2 min, followed by a slower increase for the duration of the ...
BACKGROUND:. Atherosclerotic vascular disease is a major source of morbidity and mortality. Inflammation plays an important role in atherosclerosis. The tools to systematically study the extent to which genetic variation determines risk of and progression of atherosclerosis are only now becoming available.. DESIGN NARRATIVE:. The study will evaluate the role of genetic variation in inflammatory pathway genes at 29 loci on the risk and progression of carotid artery atherosclerotic disease (CAAD). Genes to be evaluated include those potentially involved in plaque initiation and progression. The investigators will evaluate single nucleotide polymorphisms (SNPs) informative for the common locus haplotypes. Choice of informative polymorphisms for evaluation is based on the genes evolutionary history. They will evaluate progression effects in subjects with CAAD followed longitudinally by noninvasive magnetic resonance (MR) techniques over 3 years. Risk will be evaluated by case-control comparisons. ...

The experiment was carried out on 100 symptomatic patients with internal carotid artery stenosis that underwent carotid endarterectomy. Every patient had the wall of the carotid artery resected during organ harvesting surgery in order to evaluate some cytokines (TGF-β, VEGF, FGF, TNF-α) and to perform the immunohistochemistry (IHC). An immunoreactive score (IRS) was calculated based on the staining intensity and the number of cells stained. Over a 3-year period, 7 patients died, and 2 patients were lost to follow-up. The study group consisted of 91 patients. The control group comprised 20 young organ donors with confirmed death brain, who had their normal carotid artery sampled. In all healthy donors (control group) with normal carotid arteries the three cytokines (TGF-β, VEGF, TNF-α) were not discovered. The presence of FGF was confirmed in 25% of healthy donors, probably due to an intima fibroblasts activity, responsible for the synthesis of elastin and collagen to the extracellular matrix (ECM).
Stroke is the third-leading cause of death in America, and carotid artery stenosis-also known as carotid artery disease-is one of the leading risk factors for stroke, accounting for about 20 percent of strokes. To mark National Stroke Month in May, we asked University of Minnesota Health Neurosurgeon and Neurointerventionist Ramachandra Tummala, MD, to tell us five things we should know about carotid artery stenosis and its link to stroke risk.. Carotid stenosis occurs when buildup begins blocking blood flow.. Stenosis is a medical term for narrowing of blood vessels in the body due to a buildup of inflammatory substances and cholesterol deposits-called plaque. Two carotid arteries in the neck carry most of the blood flow from the heart to the brain. When stenosis occurs in these arteries it is known as carotid artery stenosis. Carotid artery stenosis can lead to a stroke.. Patients with carotid artery stenosis are at increased risk for a stroke, which can lead to disability or death. Sometimes, ...

The internal carotid artery is a major paired artery, one on each side of the head and neck, in human anatomy. They arise from the common carotid arteries where these bifurcate into the internal and external carotid arteries at cervical vertebral level 3 or 4; the internal carotid artery supplies the brain, while the external carotid nourishes other portions of the head, such as face, scalp, skull, and meninges. Terminologia Anatomica in 1998 subdivided the artery into four parts: cervical, petrous, cavernous, and cerebral. However, in clinical settings, the classification system of the internal carotid artery usually follows the 1996 recommendations by Bouthillier, describing seven anatomical segments of the internal carotid artery, each with a corresponding alphanumeric identifier-C1 cervical, C2 petrous, C3 lacerum, C4 cavernous, C5 clinoid, C6 ophthalmic, and C7 communicating. The Bouthillier nomenclature remains in widespread use by neurosurgeons, neuroradiologists and neurologists. ...

Carotid artery disease is a disease in which a waxy substance called plaque builds up inside the arteries. You have two carotid arteries, one on each side of the neck which divide into the internal and external carotid arteries. The internal arteries supply blood to the brain and the external arteries supply blood to the face, scalp, and neck... Carotid artery disease is serious because it can cause a stroke if the plaque should build up to the point it cuts off blood supply to the brain, or the plaque ruptures and a blood clot forms in the artery cutting off blood supply to the brain.. Carotid artery disease causes over half the strokes that occur in the United States. Carotid artery disease may not have any symptoms until the arteries are severely narrowed or blocked. For some people, a stroke is the first sign of the disease.. ...
This study demonstrates for the first time that expression of a recombinant protein in the adventitia by in vivo adenovirus-mediated gene transfer can result in a biological effect. Our results indicate that delivery of adenoviral vectors encoding the β-galactosidase and eNOS genes to the periarterial sheath of rabbit carotid arteries results in adventitia-specific gene transfer and expression. Expression of recombinant eNOS in the adventitia resulted in marked increase in calcium-dependent NOS activity, an elevation of cGMP levels, and a diminished sensitivity to phenylephrine. Furthermore, the recombinant eNOS is responsive to stimulation by calcium ionophore and acetylcholine, as manifested by enhanced relaxations to these agents.. Gene transfer to the adventitia by adenoviral vectors has been demonstrated by Rios and coworkers9 in monkey femoral and carotid arteries. We obtained similar adventitia-specific gene transfer in rabbit carotid arteries by instilling adenoviral vectors into the ...
BACKGROUND Low plasma concentrations of high-density lipoprotein (HDL) are associated with increased risk of cardiovascular disease. However, recently several studies have questioned the protective role of high plasma HDL levels. OBJECTIVE This study was designed to evaluate HDL functions in women with high plasma HDL cholesterol and very low risk profile with relation to subclinical carotid atherosclerosis (ATS). METHODS Included were 158 middle-aged women with plasma HDL |60 mg/dL and Framingham risk score |7% who had B-mode ultrasound of the carotid arteries. Subclinical ATS was determined by the presence of plaques and/or intima-media thickness (IMT) |1.0 mm. RESULTS ATS was observed in 51 women, with the majority (n=41) having carotid plaques, some with advanced morphology. In a multivariable model analysis, each, HDL or age, were independently associated with increased prevalence of ATS. Odds ratios for ATS were 3.1 and 2.5 greater for age|60 years and HDL |70 mg/dL, respectively. None of
Methods and Results: To identify cIMT-associated genes and genetic variants, a discovery analysis using the Illumina 200K CardioMetabochip was conducted in 3430 subjects with detailed ultrasonographic determinations of cIMT from the IMPROVE (Carotid Intima Media Thickness [IMT] and IMT-Progression as Predictors of Vascular Events in a High Risk European Population) study. Segment-specific IMT measurements of common carotid, bifurcation, and internal carotid arteries, and composite IMT variables considering the whole carotid tree (IMTmean, IMTmax, and IMTmean-max), were analyzed. A replication stage investigating 42 single-nucleotide polymorphisms for association with common carotid IMT was undertaken in 5 independent European cohorts (total n=11 590). A locus on chromosome 16 (lead single-nucleotide polymorphism rs4888378, intronic in CFDP1) was associated with cIMT at significance levels passing multiple testing correction at both stages (array-wide significant discovery P=6.75×10 -7 for ...

The cervical segment, or C1, of the internal carotid extends from the carotid bifurcation until it enters the carotid canal in the skull anterior to the jugular foramen. At its origin, the internal carotid artery is somewhat dilated. This part of the artery is known as the carotid sinus or the carotid bulb. The ascending portion of the cervical segment occurs distal to the bulb, when the vessel walls are again parallel. The internal carotid runs perpendicularly upward in the carotid sheath, and enters the skull through the carotid canal. During this part of its course, it lies in front of the transverse processes of the upper three cervical vertebrae. It is relatively superficial at its start, where it is contained in the carotid triangle of the neck, and lies behind and lateral to the external carotid, overlapped by the sternocleidomastoid muscle, and covered by the deep fascia, the platysma, and integument: it then passes beneath the parotid gland, being crossed by the hypoglossal nerve, the ...

BACKGROUND AND PURPOSE: Studies in unrelated individuals have produced conflicting findings concerning the putative association between the interleukin-6 (IL-6) -174G/C polymorphism and carotid intimal-medial thickness (IMT). We have used a family-based genetic association design to assess the heritability of carotid IMT and to investigate the hypothesized association of carotid IMT with the IL-6 to -174G/C polymorphism. METHODS: We studied 854 members of 224 white British families. The heritability of carotid IMT was determined using Multipoint Engine for Rapid Likelihood Inference. Genetic association analyses were carried out using ANOVA and family-based tests of association implemented in Quantitative Transmission Disequilibrium Test. A meta-analysis of previous studies of the association was conducted to place our result in context. RESULTS: The heritability of carotid IMT was 24%. Under a recessive model (GG+GC versus CC), there was significant evidence of association between IL-6 to the -174G/C

Common carotid artery intima-media thickness (CIMT), as measured by ultrasound, has utility in stratification of the accelerated cardiovascular risk seen in rheumatoid arthritis (RA); however, the technique has limitations. Carotid magnetic resonance imaging (MRI) is emerging as a useful research tool in the general population, but has yet to be applied in RA populations. Our objectives were to describe the utility of carotid artery MRI (carotid-MRI) in patients with RA in comparison to healthy controls and to describe the association with RA disease phenotype. Sixty-four patients with RA and no history of cardiovascular (CV) disease/diabetes mellitus were assessed for RA and CV profile, including homeostasis model assessment-estimated insulin resistance (HOMA-IR) and N-terminal pro-brain natriuretic peptide (NT-proBNP). All underwent carotid-MRI (3 T), and were compared to 24 healthy controls. Univariable analysis (UVA) and multivariable linear regression models (MVA) were used to determine

Rockville, US, 2018-Dec-26 - /EPR Network/ - Carotid artery stenting (CAS) is an endovascular procedure to treat narrowing of the carotid artery, which reduces the risk of transient ischemic attacks (TIAs) or strokes. It involves the placement of a stent in the carotid artery to treat narrowing of the carotid artery and decreases the risk of stroke. A stent is a metal or plastic tube inserted into the lumen of the carotid artery to avoid its narrowing and thereby keeping the passageway open for blood flow. Carotid stenting is the preferred therapy for patients, who do not want to undergo carotid surgery.. Get Free Sample Report here- https://www.factmr.com/connectus/sample?flag=S&rep_id=1025.

A carotid web is a very rare vascular disease of the carotid artery, leading to thrombosis and ischemic stroke. A 65-year-old male patient was admitted due to left limb weakness. On arrival, he had moderate left hemiplegia, neglect, and sensory loss; the National Institutes of Health Stroke Scale score was 8. Computed tomography angiography (CTA) and magnetic resonance (MR) examination were performed to determine the cause of basal ganglia infarction. Thin-section axial CTA showed a membrane-like structure in the posterior wall of the right common carotid artery. The sagittal reconstruction image showed a membrane-like protrusion in the posterior wall of the right common carotid artery under the right carotid sinus. The MR axial T2 image showed a membrane-like high-signal protrusion into the carotid artery lumen, which was diagnosed as a right carotid web. The patient was treated with dual antihypertensive therapy by adjusting blood pressure, controlling brain edema, improving cerebral circulation, and

Releasing NO from a stent might reduce the clinical problem of restenosis. The present study was designed to examine whether an NO-eluting covered stent can prevent neointimal formation in a porcine carotid overstretch injury model. Methods: The interior of a self-expanding polytetrafluoroethylene (ePTFE)-covered aSpire stent was coated with silicone, which contained 23.6 μg or 54.5 μg sodium nitroprusside (SNP, NO-releasing compound). The stent was implanted into carotid artery. Six pigs were implanted with stents, ...

Tissue factor (TF) is a transmembrane protein that binds factor VII/VIIa, thus activating the extrinsic blood coagulation pathway. Since this pathway appears to be involved in the formation of intravascular thrombi, the anti-rabbit TF monoclonal antibody, AP-1, was produced and tested as an antithrombotic agent in a rabbit model of recurrent intravascular thrombosis. In this model, a plastic constrictor is positioned around the injured rabbit carotid arteries, and flow is monitored with a Doppler flow probe. This produces cyclic flow variation (CFV) in the carotid artery, which is caused by recurrent formation and dislodgment of thrombi at the site of the stenosis. After monitoring CFV pattern for 30 minutes, AP-1 was infused intravenously into nine rabbits at doses of 0.05 to 1.5 mg/kg body weight, and a control monoclonal antibody that does not react with rabbit TF was infused into four additional rabbits. In all rabbits receiving AP-1, CFV was abolished, and a steady normal blood flow was ...
Accumulation of tissue iron has been implicated in development of atherosclerotic lesions mainly because of increased iron-catalyzed oxidative injury. However, it remains unknown whether cellular iron import and storage in human atheroma are related to human atheroma development. We found that transferrin receptor 1 (TfR1), a major iron importer, is highly expressed in foamy macrophages and some smooth muscle cells in intimal lesions of human carotid atheroma, mainly in cytoplasmic accumulation patterns. In 52 human carotid atherosclerotic lesions, TfR1 expression was positively correlated with macrophage infiltration, ectopic lysosomal cathepsin L, and ferritin expression. Highly expressed TfR1 and ferritin in CD68-positive macrophages were significantly associated with development and severity of human carotid plaques, smoking, and patients symptoms. The findings suggest that pathologic macrophage iron metabolism may contribute to vulnerability of human atheroma, established risk factors, and ...

PY - 1995/1. Y1 - 1995/1. N2 - The aim of this study was to assess the pattern of adaptation to severe Haemodilution in pts with normal or stenotic carotid vessels. We enrolled 180 consecutive pts undergoing total hip replacement: 138 pts had echo-Doppler documented normal carotid arteries, 10 pts had kinking and 32 pts had monolateral or bilateral stenosis of internal carotid arteries (lesions, class of stenosis 1-49%). Haemoglobin values on the 4th day after surgery was 8.7 +/- 1.2 g/dl with no statistically significant differences in pts (patients) with carotid disorders versus normal pts. No pt showed clinical signs of cerebral ischemia or brain damage in the postoperative period. These results are consistent with experimental and clinical data showing that normovolaemic anaemia is well tolerated ...
Many people are unaware that approximately 30 percent of strokes are caused by blockages in the carotid artery. Carotid artery disease is a condition characterized by a narrowing or blockage of one or both of the carotid arteries in the neck, which supply blood to the brain. Plaque, which is made up of an accumulation of fats, cholesterol, and fibrous tissue, can build up in the arteries over time, as a result of age, genetics, or an unhealthy lifestyle. The team of specialists at Stony Brook Medicine utilizes a multidisciplinary approach to diagnose and treat stroke and pre-stroke conditions, many of which are caused by a narrowing in the carotid arteries. We offer both nonsurgical and traditional treatment options. Specialists from cardiology, vascular surgery, and neurology work together to care for you and your family with compassion and expertise. What is it? Stroke is the leading cause of serious, long-term disability in the United States, and occurs when there is an interruption of blood flow
Central arterial stiffness is an independent predictor of cardiovascular risk that can be modified by exercise training. However, conventional local measures of carotid artery stiffness display conflicting responses to habitual endurance exercise in young and older adults. 2D-Strain imaging of the common carotid artery (CCA) quantifies circumferential deformation (strain) of the arterial wall across the cardiac cycle, which is more sensitive at detecting age-related alterations in CCA stiffness than conventional methods. Therefore, the study was designed to examine the relationship between habitual endurance exercise (running) and CCA 2D-Strain parameters in young and middle-aged men. Short-axis ultrasound images of the CCA were obtained from 13 young nonrunners (23 years [95% CI: 21-26]), 19 young runners (24 [22-26]), 13 middle-aged nonrunners (54 [52-56]) and 19 middle-aged runners (56 [54-58]). Images were analysed for peak circumferential strain (PCS; magnitude of deformation) as well as ...
Risk Factors in the Patients with Extracranial Carotid Atherosclerosis. By Mei-Ling Sharon Tai, Julia Sien Yuin Liew, Sheun Yu Mo and Mohamed Abdusalam Elwaifa. There are vascular risk factors known to be associated with stroke. These risk factors have been shown to either directly or indirectly lead to stroke. The risk factors include hypertension (HT), diabetes mellitus (DM), smoking, hyperlipidaemia, ischemic heart disease (IHD) and atrial fibrillation (AF). Studies have shown that carotid atherosclerosis is a cause of stroke. Extracranial carotid atherosclerosis accounts for up to 40% of the ischemic strokes in the Western countries. The latest stroke guidelines recommend the routine use of Ultrasound Carotid Doppler to assess for extracranial carotid artery atherosclerotic diseases (carotid intima media thickness, plaques, carotid stenosis) in these patients. A previous study emphasized the value of carotid ultrasonography in the detection of early extracranial carotid ...

N2 - In the present case-control study we aimed to investigate the association of common carotid arterial (CCA) stiffness with ischaemic stroke (IS) and to determine whether this relationship was independent of conventional risk factors including CCA intima-media thickness (CCA-IMT). CCA distensibility, defined as the change of CCA-diameter during the cardiac cycle, and CCA-IMT were evaluated by means of high-resolution B-mode carotid ultrasound examination in consecutive, first-ever IS patients (n = 193) and in age- and sex-matched control subjects (n = 106). The CCA distensibility (inverse of CCA stiffness) was significantly (P = 0.007) lower in IS (0.353 mm, 95% CI: 0.326-0.379) ...
The common carotid artery is found bilaterally, with one on each side of the anterior neck. Each common carotid artery is divided into an external and internal carotid artery. These arteries transfer blood to the structures inside and outside of the skull.
Background and aims: Carotid plaque is a specific sign of atherosclerosis and adults with carotid plaque are at increased risk for cardiovascular outcomes. Atherosclerosis has roots in childhood and pediatric guidelines provide cut-off values for cardiovascular risk factors. However, it is unknown whether these cut-offs predict adulthood advanced atherosclerosis. Methods: The Cardiovascular Risk in Young Finns Study is a follow-up of children that begun in 1980 when 2653 participants with data for the present analyses were aged 3-18 years. In 2001 and 2007 follow-ups, in addition to adulthood cardiovascular risk factors, carotid ultrasound data was collected. Long-term burden, as the area under the curve, was evaluated for childhood (6-18 years) risk factors. To study the associations of guideline-based cut-offs with carotid plaque, both childhood and adult risk factors were classified according to clinical practice guidelines. Results: Carotid plaque, defined as a focal structure of the ...
The external carotid arteries supply oxygenated blood to the head region. There is one external carotid artery on the right side of the neck and one on the left side of the neck. Each begins at the common carotid artery and moves up the neck until it divides into the
OBJECTIVE: Increased arterial stiffness and carotid intima-media thickness (IMT) are considered independent predictors of cardiovascular events. The aim of this study was to compare a system recently developed in our laboratory for automatic assessment of these parameters from ultrasound image sequences to a reference radio frequency (RF) echo-tracking system. METHODS: Common carotid artery scans of 21 patients with cardiovascular risk factors and 12 healthy volunteers were analyzed by both devices for the assessment of diameter (D), IMT, and distension (DeltaD). In the healthy volunteers, analyses were repeated twice to evaluate intraobserver variability. Agreement was evaluated by Bland-Altman analysis, whereas reproducibility was expressed as a coefficient of variation (CV). RESULTS: Regarding the agreement between the two systems, bias values +/- SD were 0.060 +/- 0.110 mm for D, -0.006 +/- 0.039 mm for IMT, and -0.016 +/- 0.039 mm for DeltaD. Intraobserver CVs were 2% +/- 2% for D, 5% +/- ...

Based on sample participants and measurement protocols, we assessed the reliability of CIMT and plaque presence between three clinical centers. We regarded an ICC in the range 0.4-0.75 as fair to good and , 0.75 as excellent [21]. In our results, the mean CIMT values had an excellent range of ICC, while the maximum CIMT values had a fair to good range. It is probably because the mean CIMT value is less affected by an outlier than the maximum value. We attribute these results to our protocol that allows adding the plaque thickness to CIMT if plaque exists in distal CCA. This tendency was consistent with the results from other articles [14,17]. Spearman correlation showed similar tendency, too. We could not conclude the rating of each center due to the lack of absolute right CIMT value, but from these results, center 3 was likely to provide a highly reliable value. In the separate analysis done by right and left carotid arteries, only the mean CIMT value of right carotid artery had an ...
Background/Purpose: The mechanism for the increased cardiovascular morbidity and mortality in rheumatoid arthritis (RA) is incompletely understood. In a previous analysis, we found that both the erythrocyte sedimentation rate and the C-reactive protein were associated with the carotid intima-media thickness (IMT) in RA patients, suggesting that systemic inflammation plays a role. Cytokines are important mediators in inflammation and can be measured in the serum. We examined the association between the serum concentration of cytokines/chemokines and the carotid IMT in patients with RA.. Methods: We performed a high-resolution carotid ultrasound in patients with RA for measurement of the internal and common carotid IMT, expressed as a composite. A subset of patients returned for a repeat ultrasound of the common carotid IMT, following a protocol designed to assess change. A stored sample of patients serum at baseline was used to measure 38 cytokines using a multiplex ELISA technique. We used a ...
Enhanced instrumentation allows you to scan for early detection of disease. Offering a vascular health screening adds value to your comprehensive eye health exam and expands your scope of practice.. In March I purchased a carotid artery ultrasound screening system for vascular fitness. The system allows my office to perform a non-invasive procedure which measures the thickness of the carotid artery intima layer-widely accepted as an ideal indicator for early detection of cardiovascular disease. Studies show that by evaluating the carotid artery intima thickness (CIMT) physicians obtain a good indicator of vascular disease elsewhere in the body. The ultrasound technology employed is a B-scan which is safe and can be repeated as many times as needed. In addition to measuring the artery thickness, the screening protocol also results in the reporting of the presence of plaques, their characteristics, whether soft and fibrous or hard and calcified, and the percentage of stenosis.. CIMT allows us to ...
Background: We sought to study the association between carotid stenosis and white-matter hyperintensity (WMH) among patients without intracranial large-vessel stenosis. Methods: This was a prospective study of patients with acute lacunar infarcts without concomitant intracranial large-vessel stenosis having undergone carotid ultrasonography. WMH was quantified using the modified Fazekas scale. Patients were grouped into quartiles based on the degree of carotid stenosis. The association among carotid stenosis, vascular risk factors, and WMH were modeled using logistic regression analysis. Results: In all, 100 patients with a mean age of 56.2 ± 11.7 years were studied. The quartile with the greatest carotid stenosis had a mean internal/common carotid artery peak systolic velocity ratio of 2.36. Total WMH was 4.64 in the highest quartile and 2.52 in the lowest quartile of carotid stenosis. Periventricular (pv)-WMH was significantly greater between the highest and lowest quartiles (2.80 versus ...
