Investigation of distal aortic compliance and vasodilator responsiveness in heart failure due to proximal aortic stenosis in the guinea pig. (1/1846)

Hypotension and syncope are recognized features of chronic aortic stenosis. This study examined vasomotor responses and dynamic compliance in isolated abdominal aortae after chronic constriction of the ascending aorta. Guinea pigs underwent constriction of the ascending aorta or sham operation. Sections of descending aorta were removed for studies of contractile performance and compliance. Dynamic compliance was measured using a feedback-controlled pulsatile pressure system at frequencies of 0.5, 1.5 and 2.5 Hz and mean pressures from 40 to 100 mmHg. Chronic (149+/-6 days) aortic constriction resulted in significant increases in organ weight/body weight ratios for left ventricle (58%), right ventricle (100%) and lung (61%). The presence of heart failure was indicated by increased lung weights, left ventricular end-diastolic pressure and systemic vascular resistance, reduced cardiac output and increased levels of plasma atrial natriuretic peptide (166%), adrenaline (x20), noradrenaline (106%) and dopamine (x3). Aortic rings showed similar constrictor responses to phenylephrine and angiotensin II, but maximal vasodilator responses to acetylcholine and isoprenaline were significantly increased (144% and 48% respectively). Dilator responses to sodium nitroprusside, forskolin and cromokalim were unchanged. Compliance of all vessels decreased with increasing pulsatile frequency and to a lesser extent with increased mean pressure, but were similar in aortic-constricted and control groups. Chronic constriction of the ascending aorta resulted in heart failure and increased vasodilator responses to acetylcholine and isoprenaline in the distal aorta while dynamic compliance was unchanged. We hypothesize that increased endothelium-mediated vasodilatation may contribute to hypotension and syncope in patients with left ventricular outflow obstruction.  (+info)

Development of atherosclerotic lesions in cholesterol-loaded rabbits. (2/1846)

To examine both of the target vessels and the optimal time of their endothelial denudation to study vascular restenosis after balloon injury in cholesterol-loaded rabbits, we made 36 atherosclerotic rabbits by feeding a hypercholesterol diet, and histologically examined the onset time and the development of atherosclerosis. Atheromatous changes were observed first after the 5th week in the thoracic aorta from the start of the diet, and then extended to the abdominal aorta, coronary artery with time. The atherosclerotic lesions in the thoracic aorta and the proximal portion of the coronary artery showed high-grade concentric intimal thickening with luminal stenosis. The abdominal aortic lesion mildly progressed. In the renal, carotid and femoral arteries, in contrast, slight atheroscleromatous changes developed during the diet period. These results suggest that the thoracic and abdominal aortas and the coronary artery would be suitable as target vessels to study vascular restenosis after balloon injury, and the endothelial denudation of these vessels should be performed between the 8th and 15th week in this diet protocol for an accurate analysis.  (+info)

Regression of atherosclerosis: role of nitric oxide and apoptosis. (3/1846)

BACKGROUND: We have recently found that administration of L-arginine to hypercholesterolemic rabbits induces regression of preexisting lesions. Others have previously shown that activation of the L-arginine/nitric oxide (NO) synthase pathway can induce apoptosis of vascular cells in vitro. Accordingly, the current study was designed to determine if dietary supplementation of L-arginine induces apoptosis of intimal lesions and if this effect is mediated through the NO synthase pathway. METHODS AND RESULTS: Male New Zealand White rabbits were fed a 0.5% cholesterol diet for 10 weeks and subsequently placed on 2.5% L-arginine HCl in the drinking water, and the cholesterol diet was continued for 2 weeks, at which time the aortas were harvested for histological studies. L-Arginine treatment increased the number of apoptotic cells (largely macrophages) in the intimal lesions by 3-fold (11.9+/-3.9 vs 3.9+/-1. 4 apoptotic cells/mm2, P<0.01). In subsequent studies, aortas were harvested for ex vivo studies. Aortic segments were incubated in cell culture medium for 4 to 24 hours with modulators of the NO synthase pathway. The tissues were then collected for histological studies and the conditioned medium collected for measurement of nitrogen oxides by chemiluminescence. Addition of sodium nitroprusside (10(-5) mol/L) to the medium caused a time-dependent increase in apoptosis of vascular cells (largely macrophages) in the intimal lesion. L-Arginine (10(-3) mol/L) had an identical effect on apoptosis, which was associated with an increase in nitrogen oxides released into the medium. These effects were not mimicked by D-arginine, and they were antagonized by the NO synthase inhibitor L-nitro-arginine (10(-4) mol/L). The effect of L-arginine was not influenced by an antagonist of cGMP-dependent protein kinase, nor was the effect mimicked by the agonist of protein kinase G or 8-BR cGMP. CONCLUSIONS: These results indicate that supplemental L-arginine induces apoptosis of macrophages in intimal lesions by its metabolism to NO, which acts through a cGMP-independent pathway. These studies are consistent with our previous observation that supplementation of dietary arginine induces regression of atheroma in this animal model. These studies provide a rationale for further investigation of the therapeutic potential of manipulating the NO synthase pathway in atherosclerosis.  (+info)

The value of late computed tomographic scanning in identification of vascular abnormalities after abdominal aortic aneurysm repair. (4/1846)

PURPOSE: The purpose of this study was to determine the prevalence of late arterial abnormalities after aortic aneurysm repair and thus to suggest a routine for postoperative radiologic follow-up examination and to establish reference criteria for endovascular repair. METHODS: Computed tomographic (CT) scan follow-up examination was obtained at 8 to 9 years after abdominal aortic aneurysm (AAA) repair on a cohort of patients enrolled in the Canadian Aneurysm Study. The original registry consisted of 680 patients who underwent repair of nonruptured AAA. When the request for CT scan follow-up examination was sent in 1994, 251 patients were alive and potentially available for CT scan follow-up examination and 94 patients agreed to undergo abdominal and thoracic CT scanning procedures. Each scan was interpreted independently by two vascular radiologists. RESULTS: For analysis, the aorta was divided into five defined segments and an aneurysm was defined as a more than 50% enlargement from the expected normal value as defined in the reporting standards for aneurysms. With this strict definition, 64.9% of patients had aneurysmal dilatation and the abnormality was considered as a possible indication for surgical repair in 13.8%. Of the 39 patients who underwent initial repair with a tube graft, 12 (30.8%) were found to have an iliac aneurysm and six of these aneurysms (15.4%) were of possible surgical significance. Graft dilatation was observed from the time of operation (median graft size of 18 mm) to a median size of 22 mm as measured by means of CT scanning at follow-up examination. Fluid or thrombus was seen around the graft in 28% of the cases, and bowel was believed to be intimately associated with the graft in 7%. CONCLUSION: Late follow-up CT scans after AAA repair often show vascular abnormalities. Most of these abnormalities are not clinically significant, but, in 13.8% of patients, the thoracic or abdominal aortic segment was aneurysmal and, in 15.4% of patients who underwent tube graft placement, one of the iliac arteries was significantly abnormal to warrant consideration for surgical repair. On the basis of these findings, a routine CT follow-up examination after 5 years is recommended. This study provides a population-based study for comparison with the results of endovascular repair.  (+info)

Suppression of experimental abdominal aortic aneurysms by systemic treatment with a hydroxamate-based matrix metalloproteinase inhibitor (RS 132908). (5/1846)

BACKGROUND: Abdominal aortic aneurysms (AAAs) are associated with chronic inflammation, disruption of medial elastin, and increased local production of elastolytic matrix metalloproteinases (MMPs). The purpose of this study was to investigate how treatment with a hydroxamate-based MMP antagonist (RS 132908) might affect the development of experimental AAAs. METHODS: Male Wistar rats underwent intraluminal perfusion of the abdominal aorta with 50 units of porcine pancreatic elastase followed by treatment for 14 days with RS 132908 (100 mg/kg/day subcutaneously; n = 8) or with vehicle alone (n = 6). The external aortic diameter (AD) was measured in millimeters before elastase perfusion and at death, with AAA defined as an increase in AD (DeltaAD) of at least 100%. Aortic wall elastin and collagen concentrations were measured with assays for desmosine and hydroxyproline, and fixed aortic tissues were examined by light microscopy. RESULTS: AAAs developed in all vehicle-treated rats, with a mean AD (+/- SE) that increased from 1.60 +/- 0.03 mm before perfusion to 5.98 +/- 1.02 mm on day 14 (DeltaAD = 276.4 +/- 67.7%). AAAs developed in only five of eight animals (62.5%) after MMP inhibition, with a mean AD that increased from 1.56 +/- 0.05 mm to 3.59 +/- 0.34 mm (DeltaAD = 128.1 +/- 18.7%; P <.05, vs vehicle). The overall inhibition of aortic dilatation attributable to RS 132908 was 53.6 +/- 6.8%. Aortic wall desmosine fell by 85.4% in the vehicle-treated rats (1210.6 +/- 87.8 pmol/sample to 176.7 +/- 33.4 pmol/sample; P <.05) but only by 65.6% in the animals treated with RS 312908 (416.2 +/- 120.5 pmol/sample). In contrast, hydroxyproline was not significantly affected by either elastase perfusion or drug treatment. Microscopic examination revealed the preservation of pericellular elastin and a greater degree of fibrocollagenous wall thickening after MMP inhibition, with no detectable difference in the extent of inflammation. CONCLUSIONS: Systemic MMP inhibition suppresses aneurysmal dilatation in the elastase-induced rodent model of AAA. Consistent with its direct inhibitory effect on various MMPs, RS 132908 promotes the preservation of aortic elastin and appears to enhance a profibrotic response within the aortic wall. Hydroxamate-based MMP antagonists may therefore be useful in the development of pharmacologic approaches to the suppression of AAAs.  (+info)

Experimental assessment of proximal stent-graft (InterVascular) fixation in human cadaveric infrarenal aortas. (6/1846)

OBJECTIVES: This paper investigates the radial deformation load of an aortic endoluminal prosthesis and determines the longitudinal load required to cause migration in a human cadaveric aorta of the endoprosthesis. DESIGN AND METHODS: The endovascular prosthesis under investigation was a 24 mm diameter, nitinol, self-expanding aortoaortic device (InterVascular, Clearwater, Florida, U.S.A.). Initially, a motorised digital force gauge developed an incremental load which was applied to the ends of five stent-grafts, to a maximum of 10 mm (42%) compression. Secondly, using a simple bench model, each ends of four stent-grafts were deployed into 10 cadaveric experimental aneurysm necks and a longitudinal load applied to effect distraction. RESULTS: Increasing load produced increasing percentage deformation of the stent-grafts. The mean longitudinal distraction load for an aneurysm neck of 20 mm was 409 g (200-480 g), for 15 mm was 277 g (130-410 g) and for 10 mm was 218 g (130-340 g). The aneurysm diameter and aortic calcification had p values of 0.002 and 0.047, respectively, while the p value for aneurysm neck length was less than 0.00001. CONCLUSIONS: These results suggest that there is a theoretical advantage of oversizing an aortic prosthesis and that sufficient anchorage is achieved in an aortic neck of 10 mm to prevent migration when fully deployed.  (+info)

Expression of interleukin-10 in advanced human atherosclerotic plaques: relation to inducible nitric oxide synthase expression and cell death. (7/1846)

Inflammation is a major feature of human atherosclerosis and is central to development and progression of the disease. A variety of proinflammatory cytokines are expressed in the atherosclerotic plaque and may modulate extracellular matrix remodeling, cell proliferation, and cell death. Little is known, however, about the expression and potential role of anti-inflammatory cytokines in human atherosclerosis. Interleukin-10 (IL-10) is a major anti-inflammatory cytokine whose expression and potential effects in advanced human atherosclerotic plaques have not been evaluated. We studied 21 advanced human atherosclerotic plaques. IL-10 expression was analyzed by use of reverse transcription-polymerase chain reaction and immunohistochemical techniques. Inducible nitric oxide synthase expression was assessed by using immunohistochemistry, and cell death was determined by use of the TUNEL method. Reverse transcription-polymerase chain reaction identified IL-10 mRNA in 12 of 17 atherosclerotic plaques. Immunohistochemical staining of serial sections and double staining identified immunoreactive IL-10 mainly in macrophages, as well as in smooth muscle cells. Consistent with its anti-inflammatory properties, high levels of IL-10 expression were associated with significant decrease in inducible nitric oxide synthase expression (P<0.0001) and cell death (P<0. 0001). Hence, IL-10, a potent anti-inflammatory cytokine, is expressed in a substantial number of advanced human atherosclerotic plaques and might contribute to the modulation of the local inflammatory response and protect from excessive cell death in the plaque.  (+info)

Rat sarcoma model supports both "soil seed" and "mechanical" theories of metastatic spread. (8/1846)

Following injection into the portal venous or vena caval systems, tumour cells are held up almost exclusively in the liver or lung respectively, and subsequent outgrowth of tumour only occurs in these organs. Following systemic arterial injection, cells are distributed, and subsequently grow, in a variety of organs. However, the adrenal gland supports tumour growth from much fewer cells than the lung, and this is partly due to the fact the rate of tumour cell loss in the initial 48 h is very high in the latter compared to the former organ.  (+info)

N2 - Background: The biomechanical behavior of the human abdominal aorta has been studied with great interest primarily due to its propensity to develop such maladies as atherosclerotic occlusive disease, dissections, and aneurysms. The purpose of this study was to investigate the age-related biaxial biomechanical behavior of human infrarenal aortic tissue. Methods of Approach: A total of 18 samples (13 autopsy, 5 organ donor) were harvested from patients in each of three age groups: Group 1 (,30 years old, n =5), Group 2 (between 30 and 60 years old, n =7), and Group 3 (,60 years old, n =6). Each specimen was tested biaxially using a tension-controlled protocol which spanned a large portion of the strain plane. Response functions fit to experimental data were used as a tool to guide the appropriate ...

BACKGROUND: Peripheral arterial disease and vascular calcifications contribute significantly to the outcome of dialysis patients. The aim of this study was to evaluate the prognostic role of severity of abdominal aortic calcifications and peripheral arterial disease on outcome of peritoneal dialysis (PD) patients using methods easily available in everyday clinical practice.. METHODS: We enrolled 249 PD patients (mean age 61 years, 67% male) in this prospective, observational, multicenter study from 2009 to 2013. The abdominal aortic calcification score (AACS) was assessed using lateral lumbar X ray, and the ankle-brachial index (ABI) using a Doppler device.. RESULTS: The median AACS was 11 (range 0 - 24). In 58% of the patients, all 4 segments of the abdominal aorta showed deposits, while 19% of patients had no visible deposits (AACS 0). Ankle-brachial index was normal in 49%, low (, 0.9) in 17%, and high (, 1.3) in 34% of patients. Altogether 91 patients (37%) died during the median follow-up ...

AU - Murtada, Sae Il. AU - Niestrawska, Justyna A.. AU - Holzapfel, Gerhard A.. PY - 2018/12/1. Y1 - 2018/12/1. N2 - Smooth muscle cells are one of the functional constituents in the human abdominal aorta, located in the medial layer, forming two helices similar to collagen fibers. During development, angiogenesis and vascular remodeling, smooth muscle cells experience changes in their orientation and a reorganization of their intracellular filament structure. In order to study the so far not so well-known interrelation between smooth muscle orientation and the intracellular filament structure in the human abdominal aorta a recently proposed mechanochemical model is modified. Two families of muscle fibers are introduced with a non-symmetric filament overlap behavior, and the model is implemented into a ...
Title: Propofol and Systemic Inflammatory Response in Abdominal Aortic Surgery. VOLUME: 5 ISSUE: 2. Author(s):Jose M. Rodriguez-Lopez and Francisco S. Lozano. Affiliation:Servicio de Anestesiologia,Hospital Universitario de Salamanca, Paseo de San Vicente, 58-182, 37007,Salamanca, Spain.. Keywords:Propofol, Systemic inflammatory response, Aortic surgery, Aortic cross-clamping. Abstract: Abdominal aortic surgery is relatively common associated with considerable postoperative morbidity and mortality. The aortic cross-clamping for the implantation of a vascular prosthetic graft induces a systemic inflammatory response (SIR) because of an ischemia-reperfusion (IR) injury. In our experimental models we have reported that propofol anesthesia, compared with sevoflurane, after IR modulates SIR and this effect might result in renal protection. ...

BACKGROUND: Total occlusion of the infrarenal abdominal aorta is a very rare disease in clinical practice. The clinical outcome may be poor unless management is attempted promptly. Surgical bypass has been recommended as the treatment of choice for these lesions. However, there was relatively high surgical mortality and morbidity associad with aorto-bifemoral bypass graft in patients with other systemic disease, especially coronary artery disease. As a result, the use of, thrombolysis with percutaneous transluminal angioplasty (PTA) has recently been extended to this disease as an alternative method to surgery. PTA is technically simpler with less morbidity and mortality than surgery.We report our experience with thrombolysis and balloon angioplasty of total aortic occlusion in 14 patients between March 1991 and December 1996. METHODS: Fourteen patients, whose mean age was 59+/-13 years (11 male, 3 female), serve as the studys patients. Aortography was introduced via transbrachial artery. The ...
An abdominal aorta scan uses high-frequency sound waves to visualize the abdominal aorta. Using a specialized Doppler technique, we can also measure the movement of blood within the vessels. This provides detailed pictures of these blood vessels to help physicians determine if there is enlargement of the aorta.

The prevalence of diabetes mellitus is increasing worldwide, including the nation of Poland. The aim of this prospective and observational study was to determine risk factors and the predictors of diabetes incidence in elderly women, and to calculate the diabetes incidence ratio in this population. Two-hundred women, aged 65-74, who were non-diabetic at baseline in 2012 were followed for 6.5 years. All women were checked for incident diabetes. In non-diabetic subjects, diagnostic procedures for diabetes were performed according to Polands Diabetes recommendations. Between April 2012 and September 2018, 25 women developed diabetes and the next 11 cases were diagnosed based on FPG or oral glucose tolerance test. Women with incident diabetes had significantly higher baseline FPG, triglycerides (TG), TG/HDL cholesterol ratio and visceral adiposity index (VAI) score, and lower abdominal aorta diameter (AAD), HDL cholesterol and eGFR. In the Cox proportional hazard regression analysis, only AAD | 18 mm and

PY - 1991. Y1 - 1991. N2 - Between 1986 and 1990, 11 patients with relative or absolute contraindications to standard infrarenal reconstructions underwent supraceliac aortofemoral bypass. The operation was performed through a left-flank incision extended into the eleventh intercostal space with retroperitoneal and extrapleural dissection. Indications included multiple failed infrarenal reconstructions in four patients, previous removal of infected aortofemoral bypass graft with failure of extra-anatomic bypass in five patients, prior para-aortic lymph node dissection and radiotherapy in one patient, and aortic aneurysmal disease proximal to the renal arteries in one patient. Bypass conduits included either a bifurcated Dacron graft or a tube graft to the left femoral artery with a femorofemoral ...

Atherosclerosis of aorta abdominal region arises among the first complications of increased cholesterol level in an organism. Danger of disease is that at initial stages it is practically not distinguished, complaints of the patient are absent. When the state worsens there is an abdominal pain of various intensity that depends on the volume of vessels lesion. There is a feeling of gravity and dyspepsia: appetite loss, excessive flatulency, weight loss.. Development of abdominal aorta atherosclerosis leads to more terrible complications. The most dangerous is aneurysm. This is a uniform bottle-shaped expansion of whole vessel with a thinning of its walls or local protruding aorta wall.. Such patients have nagging pains in stomach; they are localized in the left half of stomach or near umbilicus, sometimes in loin, seldom inguinal area. Pains begin from attack-like usually right after meal, then in two-three hours stop without assistance.. Feeling of pulsation in stomach is a one more diagnostic ...

Thoracic aneurysms occur in the aorta, which is the largest artery in the body. It carries blood away from the heart to all parts of the body. The portion of the aorta that runs through the chest cavity nearest the heart is called the thoracic aorta, while the portion running through the abdomen is known as the abdominal aorta. When a weakened area of the thoracic or abdominal aorta expands or bulges, it is known as a thoracic aortic aneurysm (TAA) or abdominal aortic aneurysm (AAA). Roughly 25 percent of aortic aneurysms occur in the thoracic aorta, while 75 percent occur in the abdominal aorta ...

In 1959 Cook (1) described a clinical syndrome of the occlusion of the abdominal aorta which was dominated by neurological abnormalities. He found four similar cases (2, 3) described under different names and explained differently in respect to their etiology and mechanism. On the basis of his observation of his own two cases and those from the literature, Cook gave the following clinical picture of the syndrome: rapid onset of varying degrees of paraparesis; neurological signs reaching the seventh dorsal segment; areflexia or hyporeflexia of the lower extremities, impaired proprioceptive sensibility; presence of bilateral Babinskis signs; incontinence of the feces ...

I would like to commend Norris et al . for performing an elegant and important study. 1 The authors answered the primary question of the study and showed that length of hospital stay (LOS) did not differ among the four treatment arms. The rationale for using LOS as the primary outcome measure was that it is the variable most directly proportional to an integrated final negative effect of all significant perioperative morbidity. Although the authors explain in the discussion why they chose not to focus on relatively rare events (death and myocardial infarction), they go on to summarize the important findings of the study in the abstract reporting on LOS followed immediately by the statement:Postoperative outcomes were similar among the four treatment groups with respect to death, myocardial infarction…. The article lacks a clear statement in the abstract or in the limitations section explaining that the study was insufficiently powered to test differences in these outcomes. The message to ...

Can you please tell us also about the most challenging aortic aneurysm case you managed to treat with a total endovascular solution?. A young 34-year-old mother of two children comes to mind. She had open surgery for coarctation of the abdominal aorta at the age of 18. She developed proximal and distal anastomotic aneurysms of Dacron graft from the proximal descending to the infrarenal aorta involving a reimplanted single left kidney. We performed embolisation of the residual descending aortic lumen to avoid endoleak, implanted a tapered thoracic stent graft percutaneously and, four weeks later, staged a custom-made device for the abdominal segment preserving the renal artery using fusion navigation in very short landing zones. Avoiding re-thoracotomy and laparotomy, working percutaneously and discharging this young patient after three days is so persuasive that endo, even out of instructions for use and without knowing long-term results, is a huge benefit for many patients, both elderly and ...

94. of such a variation is the comparative incidence of wounds of the vena cava and of the abdominal aorta (pp. 318, 322). Thirty-three of the former were observed, but none of the latter, presumably because wounds of the abdominal aorta were almost immediately fatal.. When the distribution of abdominal visceral injuries in this series is compared with the distribution in other reported series (table 8), two important differences are at once apparent:. 1. In general, the frequency of wounding of all organs was higher in this series than in most other series.. 2. The rate of univisceral to multivisceral wounds was strikingly reversed in comparison with earlier experiences. The assumption seems warranted that in this series a much higher proportion of severely wounded men (that is, men with multiple visceral wounds) reached forward hospitals, and were operated on, than was the case in other reported series. No other explanation seems reasonable for the overall increase in frequency of wounding of ...

If significant pressure is transmitted across percutaneously placed stem-grafts, they may prove unacceptable for abdominal aorta aneurysm repair. Therefore, we developed an in mm model to study transmission of pressure across various materials implanted in an aneurysmal lumen. A pinch roller model producing pulsatile flow through an aneurysm fashioned from heated polyethylene was used with H2O, glycerol and heparinized bovine blood. Continuous pressure readings obtained from 3 sites (above, below and mid aneurysm) were compared between different materials including bare ...
ATLANTA--Researchers have found a link between dysregulated tryptophan metabolism and abdominal aortic aneurysm, a life-threatening vascular disease, according to a new study led by Georgia State University.. Abdominal aortic aneurysm is a permanent, localized enlargement of the abdominal aorta, the largest artery in the abdomen that provides blood to the organs and tissues of the abdomen, pelvis and legs. Because the abdominal aorta is one of four sections of the aorta, the bodys main supplier of blood, a ruptured abdominal aortic aneurysm can cause life-threatening bleeding, according to the Mayo Clinic.. Abdominal aortic aneurysm occurs in up to 9 percent of adults older than 65 years of age, with about 15,000 deaths each year in the United States after rupture. Abdominal aortic aneurysms often grow slowly and without symptoms, making them difficult to detect.. There are no proven therapeutic strategies to block progression of the disease and rupture of the abdominal aorta. The only possible ...
The pathology of the human abdominal aortic aneurysm (AAA) and its relationship to the later complication of intraluminal thrombus (ILT) formation remains unclear. The hemodynamics in the diseased abdominal aorta are hypothesized to be a key contributor to the formation and growth of ILT. The objective of this investigation is to establish a reliable 3D flow visualization method with corresponding validation tests with high confidence in order to provide insight into the basic hemodynamic features for a better understanding of hemodynamics in AAA pathology and seek potential treatment for AAA diseases. A stereoscopic particle image velocity (PIV) experiment was conducted using transparent patient-specific experimental AAA models (with and without ILT) at three axial planes. Results show that before ILT formation, a 3D vortex was generated in the AAA phantom. This geometry-related vortex was not observed after the formation of ILT, indicating its possible role in the subsequent appearance of ILT ...
We describe a case of aortic coarctation at the level of the infrarenal abdominal aorta which is encountered in less than six individuals in one million. In contrast to aortic narrowing above or including the renal arteries, this seems to be a relatively benign anomaly without systemic hypertension or impaired renal function. For the first time in this type of anomaly, contrast-enhanced MR angiography (ce-MRA) on a multi-receiver channel MR system, with an 8-channel phased array coil and parallel imaging was used. Ce-MRA displayed a tortuous, narrowed aortic segment that was found to be associated with mesenteric artery stenosis and compression of the orthotopic left renal vein, also known as the nutcracker phenomenon. All major aortic branches could be depicted using 3D surface-shaded displays and subvolume maximum intensity projections (MIPs). Collateral vessels of the abdominal wall were identified using whole-volume MIPs. Since the majority of aortic malformations are diagnosed at a younger age, and

Abdominal aortic aneurysm (AAA) is a common disease for which mechanisms of formation are still not well understood. Despite a strong genetic component to AAA risk, specific risk alleles are still largely unidentified. AAA is also a localized disease with a majority occurring in the infrarenal abdominal aorta and is six times more common than aneurysms of the thoracic aorta. To determine whether risk alleles are present in functional positional candidate genes. we: 1. performed a genetic association study using DNA from AAA cases and controls in ten candidate genes and 2. performed exon sequencing on three genes with evidence of nominal association. To identify genes with regional expression in the aorta of potential relevance to AAA: 1. Illumina microarrays were used to perform a gene expression profiling of entire baboon aortas and 2. protein expression of one candidate gene, HOXA4, was examined in further detail. Single nucleotide polymorphisms in three positional candidate genes, CEBPG, PEPD and

Several studies have demonstrated that AngII infusion leads to the formation of AAAs in mice.12,13,50 AngII exerts its diverse bioactive effects primarily by activating the AT1a receptor in mice, which plays a critical role in AngII-induced AAA development.17 In addition to mediating traditional G-protein-dependent signaling, the AT1a receptor is involved in G-protein-independent signaling by forming a complex with the multifunctional scaffolding protein βarr2.19,24 In the present study, we investigated a role for βarr2 in AngII-induced AAA formation and found that βarr2 deficiency significantly attenuates AAA formation in mice both on a hyperlipidemic apoE background and on a normolipidemic C57BL/6 background (Figure 1). These studies suggest that G-protein-independent, βarr2-dependent signaling for the AT1a receptor plays a major role in AngII-induced AAA formation.. Although our present studies showed that βarr2 deficiency attenuated AngII-induced AAA formation in mice on the ...

Interventions: Blood sampling was performed at baseline, after 30 minutes of aortic cross-clamp duration, 30 and 90 minutes after reperfusion (for tumor necrosis factor-α plasma levels in infrarenal cross-clamp group), and at baseline and 90 minutes reperfusion (for neutrophil ...
This study was undertaken to analyze immediate and mid-term knitted Dacron graft dilation and to establish which parameters should be taken as a reference when aortic graft dilation is evaluated. A Dacron knitted microvel double velour vascular graft (Hemashield Gold) was implanted in 30 patients with aneurysmal (19 cases, 63%) or occlusive (11 cases, 37%) aortic disease. The stems of bifurcated prostheses (27 patients, 90%) and tube grafts (3 patients, 10%) were measured. The package sizing (labelled size) was compared with the external diameter measured intraoperatively with a slide caliper, prior to implantation and after complete clamp release. Additional measurements were obtained by ultrasound 1 and 6 months after implantation, and in 16 cases (53% of the patients) ultrasound and computed tomography (CT) were performed at the end of the first year. The means of the measurements were compared using Students t test for matched pairs. The statistical significance level was set at p values | 0.05.
Vascular Behcets disease has a poor prognosis. This poor prognosis is due to postoperative complications including pseudoaneurysm with 50% occurrence after previous surgical repair of aneurysm especially at the site of surgery. It is suggested that the fragility of the vascular wall may play a major role in this recurrence. Recent studies have demonstrated the effectiveness of endovascular stent-grafting for recurrent aortic aneurysm in patients with Behcets disease. We present a recurrent aneurysm of the abdominal aorta at a previously scarred operative site in a known case of Behcets disease. We attempted an endovascular treatment.. ...

Participants: The study of backward walking as an addictive physiotherapy procedure was conducted in the group of 65 patients who underwent abdominal aorta surgery. The patients were randomly divided into three subgroups and three various models of physiotherapy were applied. Control group has only routine physiotherapy since therapeutic group I and II have also walking exercises forward in group I and backward in group II respectively ...
Blood vessels are tubes that carry blood throughout your body. Arteries (red) carry oxygen-rich blood from the heart to the rest of your body. Blood vessels that carry blood back to your heart are called veins (blue). An abdominal aortic aneurysm occurs when a part of the largest artery in the body, the aorta, weakens and expands.. The aorta is the artery that carries blood directly from the heart. Blood then flows from the aorta into smaller arteries that supply the rest of the body. A healthy artery is smooth on the inside, which allows blood to flow easily. The part of the aorta that travels through the abdomen (stomach area) is called the abdominal aorta. Smaller arteries branch of the abdominal aorta to carry blood to organs in the abdomen. These include the renal arteries, which supply the kidneys. Lower down, the aorta divides into two iliac arteries, which supply blood to the legs.. The problem begins when the lining of the aorta is damaged or the aorta may become weakened due to certain ...
A 63-year-old female presented with proximal bilateral lower extremity pain that occurred after walking and was resolved by resting in the standing position. Her past medical history was significant for obesity, hypertension, and dyslipemia. On physical examination, the bilateral pedial and posterior tibial pulses were absent, the bilateral popliteal pulses and the left femoral pulse were weak, and the right femoral pulse was not palpable. The computed tomography angiogram revealed diffuse atherosclerotic disease involving the infrarenal abdominal aorta, causing an occlusion of distal aorta and both primitive iliac arteries with posterior spontaneous revascularization (Figure 1A, 1B); a mobile thrombus originated from the inner curve of the isthmic aorta and extended over 10cm, occluding 65% of the lumen of the descending aorta (Figure 2A, 2B).. ...
Coronary artery calcium (CAC) was measured by the average of 2 electron beam computed tomography (EBCT) measurements, with prevalent CAC defined by an average score of ,10 Agatston units, a data derived threshold determined to maximize signal to noise ratio, as previously described.13 Abdominal MRI was performed using a 1.5 Tesla whole-body MRI system (Intera, Philips Medical Systems). Six transverse slices of the infrarenal abdominal aorta were obtained using a free-breathing, ECG-gated, T2-weighted turbo spin-echo (black-blood) sequence as described previously.14 Images were analyzed by trained observers blinded to all subject data using the Magnetic Resonance Analytic Software Systems (MASS) cardiac analysis software package (Version 4.2 beta, Medis Medical Imaging Systems Inc). Atherosclerotic plaque (AP) was identified as hyperintense signal volume that protruded ≥1 mm from the endoluminal surface of the aortic wall as previously defined.15 Plaque was manually contoured in each image, and ...

Background Research: The definition of an aneurysm is permanent, localised dilatation of a blood vessel or heart chamber. The abdominal aorta is the largest blood vessel in the human body and usually has a diameter of 1.8 -2.0 centimetres (cm), dependant on age, sex and body habitus. Aortic dilatation is generally classed as an aneurysm when dilation of the vessel is 1.5 times the normal size. An abdominal aortic aneurysm (AAA) affects any part of the aorta below the diaphragm with 80 % typically being found between the renal artery and aortic bifurcation. Risk Factors There are many factors that relate to the development of AAA. Gender is one of the biggest non-modifiable risk factors, as an AAA is four to six times more likely in males compared with females. Furthermore, the development of AAA in females occurs approximately ten years later than males. The risk of AAA also increases if there is family history of the disease, especially if the relative is first degree. There is also ...
ECG-gated scans of the heart used to determine CAC were performed using a standard protocol that has been described in detail.10 At years 15 and 20, 2 sequential heart scans were obtained and their scores averaged, whereas a single scan was obtained at year 25. Image analysis was performed at a central reading center (Wake Forest University Health Sciences, Winston-Salem, NC). Trained technicians measured CAC on a workstation with Food and Drug Administration-approved calcium scoring software (Aquarius Workstation, TeraRecon, Foster City, CA).The Agatston score, corrected for slice thickness with a minimum lesion size of 4 adjacent pixels (minimum area of 1.87 mm2) and attenuation threshold of ≥130 Hounsfield units, is reported.11 For analyses comparing the absence with the presence of CAC or AAC, any CAC or AAC was considered a positive result. The previously reported year 15 CAC scores (read at a different site) were reanalyzed using the year 20 and 25 software and readers to ensure ...
To the editor: In the March 1999 issue of The American Journal of Physiology, Hardt et al. (1) presented an elegant experimental study on the validation of intravascular ultrasound (IVUS) in assessing changes in the pressure-diameter relationship in the aorta of dogs. They compared measurements of abdominal aortic diameters derived from IVUS with those obtained at the same site using implanted sonomicrometers. They then calculated the arterial compliance as the ratio of systolic to diastolic amplitude of the diameter to the amplitude of the pressure (1). The unit used to express compliance is micrometers per millimeter of mercury (μm/mmHg).. The classic definition by Spencer and Denison (3) of compliance (C) is the change in arterial blood volume (ΔV) due to a given change in arterial blood pressure (ΔP), i.e., C = ΔV/ΔP. This definition is still accepted (and therefore, C is expressed in μm3/mmHg or m3/kPa).. In clinical practice, cross-sectional compliance (CC) is utilized, assuming ...

Abdominal aortic aneurysm (AAA) repair procedures can be done surgically or through minimally invasive techniques. AAA procedures are used to treat an aneurysm (abnormal enlargement) of the abdominal aorta.
An abdominal aortic aneurysm (AAA) is a swelling in the abdominal aorta, which is the main artery that supplies blood to your body. As the AAA grows, the wall of the aorta stretches and becomes weaker, which can eventually lead to a significant risk of a ruptured AAA. This is often fatal.
Abdominal aortic aneurysm (AAA) is a focal dilatation of the abdominal aorta to more than 1.5 times its normal diameter. AAAs are classified by location as eit…
Aneurysm development is a complex process that involves synthesis and degradation of the extracellular macromolecules of the matrix. Proteinases that degrade the structural matrix are likely to have a pivotal role in this process. We have investigated 2 MMPs that account for the majority of the elastolytic activity found in AAA tissue by using 3 different techniques. Our quantitative analyses of transcript and protein levels demonstrate that both MMP-2 and MMP-9 are increased in the diseased aorta. However, only MMP-2 distinguishes between AAA and AOD, with increased production found in AAA. Additionally, there was increased activation and matrix binding of this gelatinase in AAA. MMP-9 transcript and protein were increased in both diseases to a similar extent.. Using QCRT-PCR, we detected MMP-9 in control, AOD, and AAA tissues. MMP-9 transcripts found in the control aorta may reflect the presence of subclinical atherosclerosis in some transplant specimens. These atherosclerotic changes begin in ...

1. The Carotid Screening: The sonographer will assist you to the exam table and have you lie down. Ultrasound gel will be applied to your neck area and the technologist will move a transducer (our camera so to speak) over both the RT and Lt Carotid arteries. This will allow the physician to visualize real-time the structure and integrity of the neck arteries to observing for plaque or arterial narrowing. Approximately 5-10 minutes.. 2. Abdominal Aorta Screening:. The sonographer will ask you to lift your shirt up to expose your abdomen. Ultrasound gel will be applied and the transducer moved up and down your abdomen over your aortic vessel. This portion of the test checks for enlargement of the abdominal aorta. The physician will report the results of the Carotid and Aortic exam as this portion is completed.. 3. Ankle-Brachial Indices Exam: The ABI exam will assess for peripheral arterial disease (PAD). The technologist will assist you in removing your socks, shoes and rolling up your shirt ...

CD36 and thrombi as much (however not all) individual AAAs have a tendency to end up being. Hence SMCs within elastase-perfusion-induced rat AAAs knowledge a somewhat different microenvironment than perform individual AAA SMCs and potentially fewer pathological stimuli. Not surprisingly in the absence of any small animal model of AAAs that replicates each and every possible facet of AAA pathology the current choice of an AAA model is definitely relevant in its ability to mimic several key aspects of SMC activation within human being AAAs. Since phenotypic characterization of RASMCs and assessment of their elastogenic potential (innate and induced) requires sufficient cell figures for study which cannot be from main tissue sources passaging and quantity expansion of main cells in tradition is definitely inevitable. Morphologically we discovered early passing Eand shows that SMCs produced from an AAA keep an changed gene expression lifestyle at least before third passing. At the moment we have not ...

A dislocated joint usually can be successfully reduced into its normal position only by a trained medical professional. Trying to reduce a joint without any training could substantially worsen the injury.[15] X-rays are usually taken to confirm a diagnosis and detect any fractures which may also have occurred at the time of dislocation. A dislocation is easily seen on an X-ray.[16] Once a diagnosis is confirmed, the joint is usually manipulated back into position. This can be a very painful process, therefore this is typically done either in the emergency department under sedation or in an operating room under a general anaesthetic.[17] It is important the joint is reduced as soon as possible, as in the state of dislocation, the blood supply to the joint (or distal anatomy) may be compromised. This is especially true in the case of a dislocated ankle, due to the anatomy of the blood supply to the foot.[18] Shoulder injuries can also be surgically stabilized, depending on the severity, using ...

PTSD symptoms may result when a traumatic event causes an over-reactive adrenaline response, which creates deep neurological patterns in the brain. These patterns can persist long after the event that triggered the fear, making an individual hyper-responsive to future fearful situations.[20][81] During traumatic experiences the high levels of stress hormones secreted suppress hypothalamic activity that may be a major factor toward the development of PTSD.[82] PTSD causes biochemical changes in the brain and body, that differ from other psychiatric disorders such as major depression. Individuals diagnosed with PTSD respond more strongly to a dexamethasone suppression test than individuals diagnosed with clinical depression.[83][84] Most people with PTSD show a low secretion of cortisol and high secretion of catecholamines in urine,[85] with a norepinephrine/cortisol ratio consequently higher than comparable non-diagnosed individuals.[86] This is in contrast to the normative fight-or-flight ...

A trauma center (or trauma centre) is a hospital equipped and staffed to provide care for patients suffering from major traumatic injuries such as falls, motor vehicle collisions, or gunshot wounds. A trauma center may also refer to an emergency department (also known as a "casualty department" or "accident and emergency") without the presence of specialized services to care for victims of major trauma. In the United States, a hospital can receive trauma center status by meeting specific criteria established by the American College of Surgeons (ACS) and passing a site review by the Verification Review Committee.[1] Official designation as a trauma center is determined by individual state law provisions. Trauma centers vary in their specific capabilities and are identified by "Level" designation: Level I (Level-1) being the highest and Level III (Level-3) being the lowest (some states have five designated levels, in which case Level V (Level-5) is the lowest). The highest levels of trauma centers ...
