The background image is determined from a digitized image taken a few moments before injection of the contrast material. The resulting angiogram is a high-contrast image of the vessel. This subtraction technique allows extraction of a high-intensity signal from the superimposed background information. The image is thus the result of the differential absorption of X-rays by different tissues.Blood Vessel Prosthesis: Device constructed of either synthetic or biological material that is used for the repair of injured or diseased blood vessels.Blood Vessel Prosthesis Implantation: Surgical insertion of BLOOD VESSEL PROSTHESES to repair injured or diseased blood vessels.Risk Factors: An aspect of personal behavior or lifestyle, environmental exposure, or inborn or inherited characteristic, which, on the basis of epidemiologic evidence, is known to be associated with a health-related condition considered important to prevent.Carotid Stenosis: Narrowing or stricture of any part of the CAROTID ARTERIES, most often due to atherosclerotic plaque formation. Ulcerations may form in atherosclerotic plaques and induce THROMBUS formation.

It is sometimes useful also as an adjunct in the treatment of tonic-clonic, myoclonic, and atonic seizures, particularly in women whose seizures occur or are exacerbated at specific times in the menstrual cycle. However, its usefulness is transient often because of rapid development of tolerance. Its antiepileptic effect may be due to its inhibitory effect on brain carbonic anhydrase, which leads to an increased transneuronal chloride gradient, increased chloride current, and increased inhibition. (From Smith and Reynard, Textbook of Pharmacology, 1991, p337)Aortic Aneurysm, Abdominal: An abnormal balloon- or sac-like dilatation in the wall of the ABDOMINAL AORTA which gives rise to the visceral, the parietal, and the terminal (iliac) branches below the aortic hiatus at the diaphragm.Life Tables: Summarizing techniques used to describe the pattern of mortality and survival in populations.

It distributes to the neck, thoracic wall, spinal cord, brain, meninges, and upper limb.Atherectomy: Endovascular procedure in which atheromatous plaque is excised by a cutting or rotating catheter. It differs from balloon and laser angioplasty procedures which enlarge vessels by dilation but frequently do not remove much plaque. If the plaque is removed by surgical excision under general anesthesia rather than by an endovascular procedure through a catheter, it is called ENDARTERECTOMY.Postoperative Complications: Pathologic processes that affect patients after a surgical procedure. They may or may not be related to the disease for which the surgery was done, and they may or may not be direct results of the surgery.Iofetamine: An amphetamine analog that is rapidly taken up by the lungs and from there redistributed primarily to the brain and liver. It is used in brain radionuclide scanning with I-123.Graft Occlusion, Vascular: Obstruction of flow in biological or prosthetic vascular grafts.Regional Blood Flow: The flow of BLOOD through or around an organ or region of the body.Cerebral Angiography: Radiography of the vascular system of the brain after injection of a contrast medium.Vertebrobasilar Insufficiency: Localized or diffuse reduction in blood flow through the vertebrobasilar arterial system, which supplies the BRAIN STEM; CEREBELLUM; OCCIPITAL LOBE; medial TEMPORAL LOBE; and THALAMUS.

The evolution of early fibromuscular lesions hemodynamically induced in the dog renal artery. I. Light and transmission electron microscopy. (1/2527)

In view of the important roles of arterial intimal fibromuscular lesions as precursors of atherosclerotic plaque and occlusive lesions in arterial reconstructions, a model has been developed for the rapid hemodynamic induction of these lesions by anastomosis of the dog right renal artery to the inferior vena cava. Light and transmission electron microscopic observations were made on the arterial shunt after periods of rapid flow ranging form 10 minutes to 2 hours to identify initial factor(s) and evolutionary mechanisms in the etiology of the lesions. The sequence of events included aberrations in ruthenium red staining of the endothelial luminal membrane at 10 minutes, multilayered thickening of the subendothelial basement membrane (BM) at 15 minutes, and initial reorientation and migration of smooth muscle cells (SMC) into the intima along with the appearance of areas of degeneration of the internal elastic lamina (IEL) at 30 minutes. The endothelial cells were still intact in some areas overlying the SMC migration and IEL degeneration, but they were separating from the surface in other such areas. As subendothelium became exposed, some platelet adherence was noted. By 2 hours, the entire wall reaction was fully developed. Initial observations indicate that in the evolution of this hemodynamically induced lesion visible alteration in the endothelial cells is not prerequisite to degeneration of the underlying IEL and reorientation and migration of medial SMC.  (+info)

Prevalence of peripheral arterial disease and associated risk factors in American Indians: the Strong Heart Study. (2/2527)

Studies of peripheral arterial disease (PAD) in minority populations provide researchers with an opportunity to evaluate PAD risk factors and disease severity under different types of conditions. Examination 1 of the Strong Heart Study (1989-1992) provided data on the prevalence of PAD and its risk factors in a sample of American Indians. Participants (N = 4,549) represented 13 tribes located in three geographically diverse centers in the Dakotas, Oklahoma, and Arizona. Participants in this epidemiologic study were aged 45-74 years; 60% were women. Using the single criterion of an ankle brachial index less than 0.9 to define PAD, the prevalence of PAD was approximately 5.3% across centers, with women having slightly higher rates than men. Factors significantly associated with PAD in univariate analyses for both men and women included age, systolic blood pressure, hemoglobin A1c level, albuminuria, fibrinogen level, fasting glucose level, prevalence of diabetes mellitus, and duration of diabetes. Multiple logistic regression analyses were used to predict PAD for women and men combined. Age, systolic blood pressure, current cigarette smoking, pack-years of smoking, albuminuria (micro- and macro-), low density lipoprotein cholesterol level, and fibrinogen level were significantly positively associated with PAD. Current alcohol consumption was significantly negatively associated with PAD. In American Indians, the association of albuminuria with PAD may equal or exceed the association of cigarette smoking with PAD.  (+info)

Transforming growth factor-alpha acting at the epidermal growth factor receptor reduces infarct volume after permanent middle cerebral artery occlusion in rats. (3/2527)

Transforming growth factor-alpha (TGF-alpha) is a ligand for the epidermal growth factor (EGF) receptor (EGFR), and is more abundant than EGF in the brain. The authors studied whether administration of exogenous TGF-alpha into the brain can protect neurons against ischemia in a model of permanent middle cerebral artery (MCA) occlusion in the rat, and whether any effect of TGF-alpha was mediated by EGFR by administering 4,5-dianilinophthalimide (DAPH), a protein-tyrosine kinase inhibitor with high selectivity for EGFR. Rats received either TGF-alpha (10 or 25 ng), DAPH (100 ng), DAPH plus TGF-alpha (25 ng), or vehicle in the ipsilateral first ventricle. Drugs were administered twice: 30 minutes before and 30 minutes after MCA occlusion, and infarct volume was evaluated 24 hours later. Transforming growth factor-alpha at the dose of 25 ng caused a statistically significant reduction of infarct volume (60%) in relation to ischemic rats administered vehicle. This reduction was no longer seen when TGF-alpha was administered in combination with DAPH. The present results show that TGF-alpha can protect neurons from ischemic damage, and that this effect is mediated by EGFR. It is suggested that activation of EGFR-mediated intracellular signalling pathways contributes to the survival of neural cells susceptible to ischemic injury.  (+info)

3D angiography. Clinical interest. First applications in interventional neuroradiology. (4/2527)

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)

Inhibition of nitric oxide but not prostacyclin prevents poststenotic dilatation in rabbit femoral artery. (5/2527)

BACKGROUND: Poststenotic dilatation (PSD) occurs in a low-pressure region where recirculation eddies oscillate in size during the cardiac cycle. NO may be an important mediator of PSD. METHODS AND RESULTS: Femoral arteries of 7 adult male New Zealand White rabbits were stenosed bilaterally to achieve a diameter reduction of 70. 9+/-6.7% (n=14). At the time of stenosis, the adventitia of one of the arteries was coated with 1 mmol/L of NG-nitro-L-arginine methyl ester (L-NAME) in 22% (wt/vol) Pluronic gel, while the contralateral vessel was coated with gel without L-NAME. In stenosed femoral arteries that were treated with gel without L-NAME, a maximum PSD of 30.99+/-7.92% (n=7) was observed in polymer casts at 3 days relative to the mean proximal diameter of 1.57+/-0.25 mm at a position 12 mm upstream of each stenosis. In contrast, the vessels treated with L-NAME exhibited a maximum PSD of only 7.16+/-8.81% (n=7) relative to the mean proximal diameter of 1.55+/-0.16 mm. L-NAME caused a 76. 9% reduction (P<0.001, n=7) of PSD. Similarly, NG-monomethyl-L-arginine 1 mmol/L and NG-nitro-L-arginine 10 micromol/L attenuated PSD by 57.5% (P<0.001, n=6) and 63.9% (P<0.05, n=6), respectively. Indomethacin 10 micromol/L caused no reduction in PSD. Arterial rings obtained from the poststenotic region were more sensitive and responsive to acetylcholine than those obtained proximal to the stenosis. CONCLUSIONS: NO, but not prostacyclin, is a major mediator of PSD.  (+info)

Sites of stenosis in AV fistulae for haemodialysis access. (6/2527)

BACKGROUND: A large proportion of late failures of radiocephalic arteriovenous fistulae are related to the progression of intimal hyperplasia. The aetiology of this process is still unknown but the fistula configuration and resultant haemodynamics have been implicated. This clinical study was devised to identify sites of stenosis in patients with fistulae and relate the findings to various clinical and geometrical parameters. METHOD: Measurement of anastomotic length and angle was made intraoperatively in 25 consecutive fistulae. Post-operative assessment was carried out at regular intervals using duplex and colour-flow ultrasonography. RESULTS: Stenoses were present in all 25 of the fistulae studied at 3 months. The stenoses could be classified to three specific sites: at the anastomosis (Type 1), on the inner wall of the curved region of the cephalic vein (Type 2) and just proximal to this curved segment where the vein straightens out (Type 3). Most of Type 1 and Type 2 stenoses were not progressive while Type 3 stenoses were generally progressive. CONCLUSION: These findings emphasize the need for an effective surveillance programme of AV fistulae.  (+info)

The endovascular management of blue finger syndrome. (7/2527)

OBJECTIVES: To review our experience of the endovascular management of upper limb embolisation secondary to an ipsilateral proximal arterial lesion. DESIGN: A retrospective study. MATERIALS AND METHODS: Over 3 years, 17 patients presented with blue fingers secondary to an ipsilateral proximal vascular lesion. These have been managed using transluminal angioplasty (14) and arterial stenting (five), combined with embolectomy (two) and anticoagulation (three)/anti-platelet therapy (14). RESULTS: All the patients were treated successfully. There have been no further symptomatic embolic episodes originating from any of the treated lesions, and no surgical amputations. Complications were associated with the use of brachial arteriotomy for vascular access. CONCLUSIONS: Endovascular techniques are safe and effective in the management of upper limb embolic phenomena associated with an ipsilateral proximal focal vascular lesion.  (+info)

Infrainguinal revascularisation in the era of vein-graft surveillance--do clinical factors influence long-term outcome? (8/2527)

OBJECTIVES: To investigate the variables affecting the long-term outcome of infrainguinal vein bypass grafts that have undergone postoperative surveillance. DESIGN: A retrospective analysis. PATIENTS AND METHODS: Details of 299 consecutive infrainguinal vein grafts performed in 275 patients from a single university hospital were collected and analysed. All grafts underwent postoperative duplex surveillance. Factors affecting patency, limb salvage and survival rates were examined. These factors were gender, diabetes, hypertension, aspirin, warfarin, ischaemic heart disease, run-off, graft type, early thrombectomy, level of anastomoses and indication for surgery. RESULTS: The 6-year primary, primary assisted and secondary patency rates were 23, 47, and 57%, respectively. Six-year limb salvage and patient survival were 68 and 45%, respectively. Primary patency was adversely influenced by the use of composite vein grafts. Early thrombectomy was the only factor that significantly influenced secondary patency. Limb salvage was worse in diabetic limbs, limbs with poor run-off and in grafts that required early thrombectomy. Postoperative survival was better in males, claudicants and in patients who took aspirin. CONCLUSIONS: Although co-morbid factors did not influence graft patency rates, diabetes did adversely effect limb salvage. This study, like others before it, confirms that aspirin significantly reduces long-term mortality in patients undergoing infrainguinal revascularisation.  (+info)

Hyperhomocysteinemia is implicated in retinal neurovascular illnesses including arterial occlusive disease, venous occlusive pseudoexfoliation and disease glaucoma. research to elucidate systems of HHcy-linked retinal disease. A medically relevant experimental program may be the mouse deficient or inadequate the gene encoding CBS enabling studies of the consequences of gentle to serious endogenous elevation of Hcy [30]. In prior studies, we analyzed implications on retina function and framework using either mice, that have a much milder HHcy with ~4C7 collapse upsurge in plasma Hcy (and a 2-collapse upsurge in retinal Hcy) and a standard lifespan. Our function shows that both mice possess retinal neuronal disruption and participation from the retinal vasculature [31C36]. To understand systems for HHcy-induced retinal neuronal loss of life we previously looked into the function of excitotoxicity and oxidative tension using perforated patch clamp evaluation and fluorescent recognition of ...

Systolic pressure at ankle level was measured at the Arteria tibialis posterior and the Arteria dorsalis pedis. Two individual series of measurements of arterial pressures per subject across the assessed visits were selected for the analysis. For the first analysis (worst change analysis) the series of measurements in the one artery which has the worst change from Baseline at the final measurement was used. For the second analysis (worst value analysis) the series of measurements which has the worst final post-Baseline measurement was used. The series relevant for the analyses was selected from the series for the affected leg or legs only. The selection is 1 out of up to 4 series available per subject. Series without Baseline value and series with at least 1 measurement of more than 150 mmHg were excluded from the selection process due to the suspicion of media sclerosis of the lower limb artery ...
The prevalence of PAOD in patients with CAD ranges from 5 to 40% (5,10,21-26). Such broad range may be justified by the fact that prevalence studies enroll different populations, are not randomized, investigate few clinical presentations of coronary disease, and use different diagnostic methods. Most studies that used ABPI enrolled small samples, sometimes only hospitalized patients who probably had more severe CAD. Therefore, comparisons with results of studies that selected large and diversified samples of patients with CAD are difficult (10,19). The measurement of ABPI is a widely accepted method for epidemiological studies (13,14). However, results vary according to the time when patients are examined and who performs the measurements (27). This index also shows a greater number of false-negative results among patients with diabetes because of the calcification of artery walls. It is estimated that 5 to 10% of patients with diabetes have an artificial elevation of blood pressure due to the ...

Of the approximately 8 million Americans who suffer from ischemic peripheral arterial occlusive disease (PAOD), many present with intermittent claudication, or pain associated with exercise. Impaired vasodilation of resistance vessels is a potential explanation for this symptom. Occluded arteries can lead to increased flow through collateral vessels, which function as natural bypasses around the obstruction. This increase in blood flow and resulting shear stress can cause outward remodeling, or arteriogenesis, which improves the efficacy of collaterals. However, following femoral artery ligation in a mouse model of chronic ischemia, vasodilation in the stem region of collateral vessels is impaired at day 7. In the outwardly remodeled collateral stem, the vessel diameter increase is not associated with cell proliferation, suggesting the functionality of the present smooth muscle cells (SMCs) may account for the impaired vasodilation. A potential mechanism for increased vessel diameter in the collateral
BACKGROUND: Peripheral arterial occlusive disease (PAOD) is a common cause of morbidity and mortality due to cardiovascular disease in the general population. Although numerous treatments have been adopted for patients at different disease stages, no option other than amputation is available for patients presenting with critical limb ischaemia (CLI) unsuitable for rescue or reconstructive intervention. In this regard, prostanoids have been proposed as a therapeutic alternative, with the aim of increasing blood supply to the limb with occluded arteries through their vasodilatory, antithrombotic, and anti-inflammatory effects. This is an update of a review first published in 2010. OBJECTIVES: To determine the effectiveness and safety of prostanoids in patients with CLI unsuitable for rescue or reconstructive intervention. SEARCH METHODS: For this update, the Cochrane Vascular Information Specialist searched the Specialised Register (January 2017) and the Cochrane Central Register of Controlled ...

Hypertension (HT) is the leading preventable cause of premature death worldwide, and about every third person suffers from hypertension (1). In the long run, high blood pressure damages important organs such as the heart, blood vessels, the brain and the kidneys. Consequential diseases such as myocardial infarction, stroke, peripheral arterial occlusive disease, retinal damage or kidney damage result from the damaged vessels caused by high blood pressure.. Inflammation is a hallmark of hypertension, and there is a mounting evidence suggesting that chronic low-grade inflammation contributes to cardiovascular disease (CVD) including HT (2-5). Endothelial dysfunction, oxidative stress, cytokines, toll-like receptors, inflammasomes, and gut microbiome interact in a complex and intricate way (6). Reducing inflammation therefore contributes to successful prevention and management of hypertension. Systemic inflammation can also be triggered by food. Proteins or protein-derived compounds that occur in ...

Among high risk patients with known occlusive arterial disease and a greater than 3% annual risk of a vascular event (defined as non-fatal myocardial infarction, non-fatal stroke, or vascular death), the benefits of aspirin substantially outweigh the risks of bleeding. A recent meta-analysis of randomised trials of antiplatelet drugs versus control showed that for every 1000 such patients treated for a year, aspirin would be expected to prevent about 10-20 vascular events and cause one or two major gastrointestinal bleeds.1 In a wide range of high risk … ...

A method of surgically treating occlusive disease in an intraluminal tissue using both a retractor (6) and a retractable one-piece stent. The stent is constructed and arranged such that it can exist in at least a stable initial collapsed state (12) and a stable deployed expanded state (10). In conjunction with the retractor, the stent is positioned at an appropriate location within an occluded intraluminal tissue and converted from a stable initial collapsed state to a stable deployed expanded state, and is then converted to a collapsed state and removed before significant restenosis occurs.
LCX artery occlusions are estimated to account for 20% of MIs.5,6 They may pose a diagnostic dilemma, primarily if the ECG findings are non-diagnostic for STEMI. Subsequently, these patients are more likely to undergo PCI more than 24 hours from onset of symptoms compared to patients with more readily recognizable left anterior descending (LAD) and right coronary artery (RCA) occlusions.5 LCX lesions are associated with increased risk of heart failure and mortality at 90 days and 1 year compared to RCA and LAD lesions.7 In addition, there have been multiple reports indicating higher peak levels of cardiac biomarkers, suggesting larger infarct sizes and thus more myocardial necrosis.8. Attempts at improving early diagnosis of total occlusion lesions in the LCX have had limited success. According to one study, angiography-proven LCX total artery occlusions only met STEMI criteria 46% of the time, and the addition of posterior leads (V7-V9) only improved sensitivity 6-14% of the time.9 Isolated V2 ...
Various peripheral arterial occlusive lesions have traditionally been managed with surgical therapy. However, endoluminal intervention with catheter-based techniques has become quite common and, in many cases, is now the treatment of choice.
A PubMed search was conducted with the question to evaluate the evidence on the optimal reference standard for radiological sequencing to investigate and confirm a clinical diagnosis of PAES.

Endovascular treatment is an established modality of femoropopliteal occlusive disease. However, there are conflicting results concerning the choice of applying percutaneous transluminal angioplasty (PTA) or stenting (ST). Aim of this study, is the systematic review of the most recent studies in the international references where the results of the two methods are compared, in order to determine, using standard evidence based criteria, the safety and effectiveness of the two methods. Screening of the database Medline/PubMed and Cochrane, covering the period between January 1999 to December 2010 with additional literature search of the references of the articles was done in order to discover the studies that deal with the subject of this systematic review. The investigation was limited in meta-analysis and either randomized or not controlled trials. The critical evaluation of the studies was performed according to the Impact factor of the Journal on which they were published. Sixteen studies were ...

Peripheral Arterial Occlusive Disease (PAOD) is an acquired inflammatory disease where a peripheral artery becomes occluded due to the buildup of atherosclerotic plaques. In patients that possess collateral arteries, an occlusion can lead to shear induced outward remodeling, arteriogenesis, of these collaterals, partially restoring blood flow. However, newly remodeled collaterals exhibit reduced functional vasodilation, which may impair normal activity, such as ambulation. To model chronic ischemia and arteriogenesis in collaterals, a femoral artery ligation in a murine hindlimb is commonly performed. Previous efforts by our group involved measurements of collateral artery diameter to assess the impact of arteriogenesis on functional vasodilation/vascular reactivity; however diameter measurements are not as descriptive as an assessment of flow, and performing particle image velocimetry allows the change in blood flow control to be investigated. Particle image velocimetry was performed in the profunda
In patients with peripheral arterial disease, obstructing plaques caused by atherosclerotic occlusive disease commonly occur in the infrarenal aorta and iliac arteries. Atherosclerotic plaques may induce symptoms either by obstructing blood flow or by breaking apart and embolizing atherosclerotic and/or thrombotic debris to more distal blood ...

It is well recognised that vascular tissue and mechanisms of cervical arterial dysfunction (CAD) may give rise to pain in the cranio-cervical region (Taylor and Kerry 2005). It is perhaps less well known that vascular tissue can be the source of pain syndromes throughout the body, ranging from the obvious - abdominal aortic aneurysm (low back pain), through to the less obvious (or less well known) distal limb pain/numbness as a result of popliteal artery entrapment syndrome (PAES). PAIN may be local due to a nociceptor response in the tunica adventitia due to underlying pathology (arterial dissection, atherosclerosis, aneurysm) or distal due to ischaemia (which may be movement or exercise induced ...

Fig. 2. Differences in collateral growth and tissue recovery in animal models versus humans with arterial occlusive disease. (A) After an acute arterial ligation (shown here in a mouse), there is a strong pressure gradient between the proximal and distal sides of the occlusion (orange line). This redirects the blood flow into adjacent arterioles and causes a strong shear-stress-mediated opening of collateral channels, which restore blood flow into the hypoxic areas. In the hypoxic tissues, ischemic tissue damage (necrosis) occur if the blood flow is not restored within the first hours after the occlusion. Necrosis induces acute inflammation, and recruited inflammatory cells produce angiogenic cytokines such as VEGF. The hypoxia itself activates factors such as HIF that stimulate the production of VEGF among other factors, and angiogenesis. Distal angiogenesis, along with the growth of collaterals, contributes to the tissue recovery by the formation of connections between the collaterals and the ...
The possibility that variation in the extent of native collateral circulation is an important determinant of variation in ischemic injury when acute arterial occlusion occurs or disease becomes manifest has historically been overlooked or minimized-, with the exception of those who study or treat acute ischemic stroke7-14 (and references therein), some coronary investigators4-6,69 (and references therein), and among vascular surgeons who frequently encounter or perform arterial occlusions.70,71 This presumably extends, in part, from the small diameter typical of native collaterals in most healthy individuals that is beyond the resolution of digital angiography (,0.2 mm), from the misconception that such minute vessels cannot mediate significant flow in the acute setting until remodeling has occurred, and from the inability to experimentally change native collateral extent to test its importance. The latter restriction has begun to yield in recent studies in which collateral extent was found to ...

BACKGROUND: Magnetic resonance (MR)-guided vascular interventions are of increasing interest, and, with the use of contrast-enhanced techniques, intraarterial contrast-enhanced MR angiography (ia-ce-MRA) competes with intraarterial digital subtraction angiography (ia-DSA) for the diagnostic evaluation of the infrainguinal vessel tree. PURPOSE: To assess the diagnostic value of ia-ce-MRA and high-resolution T1-weighted (hr-T1w) imaging compared to the gold-standard ia-DSA for residual stenosis and local dissections after femoropopliteal recanalization in patients with peripheral arterial occlusive disease (PAOD). MATERIAL AND METHODS: Eight patients with PAOD and short vessel occlusion of their femoropopliteal arteries underwent recanalization and balloon positioning under DSA. Patients were transferred to a short-bore MR scanner. Percutaneous transluminal angioplasty (PTA) was accomplished under MR fluoroscopy. Pre- and postinterventional ia-ce three-dimensional (3D) gradient-echo MRA with ...
In medicine, aortoiliac occlusive disease, also known as Leriches syndrome and Leriche syndrome, is a form of central artery disease involving the blockage of the abdominal aorta as it transitions into the common iliac arteries. Classically, it is described in male patients as a triad of the following signs and symptoms: claudication of the buttocks and thighs absent or decreased femoral pulses erectile dysfunction This combination is known as Leriche syndrome. However, any number of symptoms may present, depending on the distribution and severity of the disease, such as muscle atrophy, slow wound healing in the legs, and critical limb ischemia. Treatment involves revascularization typically using either angioplasty or a type of vascular bypass Kissing balloon angioplasty +/- stent, so named because the two common iliac stents touch each other in the distal aorta. Aorto-iliac bypass graft Axillary-bi-femoral and femoral-femoral bypass (sometimes abbreviated "ax-fem fem-fem") The condition was ...
Intermittent claudication, according to the Fontaine classification, is a classical symptom of stage II peripheral arterial occlusive disease (PAOD) of the lower limbs. It results from the progression of atherosclerosis leading to the narrowing and complete occlusion of arteries. It manifests with pain in the muscles of the lower limbs which forces the patients to interrupt their current activity. Supervised treadmill training is believed to lead to the most favourable outcomes in the form of improved pain-free walking distance and maximum walking distance. The improvement in pain related to intermittent claudication and in functional performance are probably the combined effect of various mechanisms in response to the exercise training. The most important mechanisms include: improved skeletal muscle metabolism, favourable haemorheologic changes, delayed progression of atherosclerosis, peripheral blood flow adaptation, improved economics of walking, and changed perception of pain. The role of ...
Freedom from a composite of target vessel restenosis, major index limb amputation, and device- or procedure-related death at 30 days was defined as the primary endpoint. "The primary effectiveness endpoint was freedom from target lesion restenosis at 12 months. Secondary endpoints were acute device and procedural success and clinically assessed primary patency," the authors write.. Results. The registry results showed a 99.4% freedom at 30 days from the composite safety endpoint. There was 89.3% freedom from target lesion restenosis in the overall population at 24 months. In long lesions up to 50cm, the freedom from target lesion restenosis was 88.2%; in patients with in-stent restenosis this figure was 84.6%. The clinically assessed primary patency was 75.6% and more than 76% of patients showed improvement of at least one Rutherford category.. Editorial comment. In an accompanying editorial comment in the journal, Ivan P Casserly, Dublin, Ireland, writes: "Most endovascular specialists are ...
OBJECTIVE AND DESIGN This study was designed to test the hypothesis that initial TcPO2 helps predict clinical outcome in vascular patients treated with spinal cord stimulation. A randomized-controlled study with one year follow-up was made in 86 Fontaine stage IV patients with endstage peripheral arterial occlusive disease (PAOD) undergoing 21 day intravenous prostaglandin E1 (PGE1) therapy for nonhealing ulcers. MATERIALS AND METHODS All patients had arteriosclerosis, 13 also diabetes mellitus. Entry criteria included: non-reconstructible PAOD as proven by intra-arterial angiography or patient condition, ankle systolic pressure | 50 mmHg, severe rest pain despite analgetic medication, and presence of nonhealing foot ulcers or dry gangrene. One week after the start of PGE1 therapy, patients were randomized into receiving SCS plus PGE1 (n = 45 patients), or just PGE1 (n = 41 patients). Follow-up examinations were done at 1, 3, 6 and 12 months. BASELINE: There were no significant differences between
Endovascular treatment of occlusive disease of the aortic bifurcation is challenging. We developed the Covered Endovascular Reconstruction of Aortic Bifurcation or CERAB-technique, as a new approach for extensive and/or recurrent aortoiliac occlusive disease using three covered balloon expandable stents to reconstruct the aortic bifurcation. This configuration provides the ability to deal with TransAtlantic Inter-Society Consensus (TASC II) C and D lesions, simulating a neo-bifurcation or flow divider in combination with the benefits of covered stents. The intervention can be performed percutaneously or as a hybrid procedure. Initial results are encouraging and further studies are indicated.. ...

[more ▼]. OBJECTIVE: To determine postoperative and long-term outcome and assess the relevance of abdominal ultrasound (US) after surgery for abdominal aortic aneurysm (AAA) or aortoiliac occlusive disease (AIOD). METHODS: Records of 1704 consecutive patients having graft implantation from 1988 to 2000, either for AAA (n = 1144) or for AIOD (n = 560), were reviewed. In 2006, follow-up was 9180 patients-years for the AAA group and 5450 patients-years for the AIOD group. Among 1006 alive patients, 377 were invited randomly for US and clinical examination. RESULTS: Hospital death occurred in 99 patients (8.6%) of the AAA group (53% in ruptured and 2% in elective AAA), and in 18 patients of the AIOD group (3.2%). There were 581 late deaths, ...
Results. The frequencies of -108T allele, which determine lower paraoxonase level, were similar in the groups of AAA (0.462) and AIOD (0.479) patients. The lower surgical repair age in patients in both groups was significantly associated with smoking and the higher levels of total cholesterol (TC), low density lipoprotein cholesterol (LDLC), and triglicerides (TG) and values of TC/HDLC. In the AAA group the same negative relation was noted with BMI index. The higher values of %HDLC display the protective effect on AAA/AIOD progression. In the AIOD group positive relations were also seen with HDLC/LDLC index and diabetes. Associations between high density lipoprotein cholesterol (HDLC) fraction and age of AIOD repair were stronger in -108T allele carriers. Age of AAA surgical repair was independently related to smoking and TG level, and age of AIOD surgical repair was independently related to smoking, diabetes and TC level. These effects were stronger in PON1-108CC homozygotes ...
Chronic MCA occlusion as a cause of hemodynamic ischemic stroke is not a prominent clinical issue worldwide.1 While acute occlusion of the MCA is commonly caused by an embolic thrombus,3 4 atherosclerotic occlusion of the intracranial arteries is more prevalent in Asians. Patients with chronic proximal MCA occlusion may have minor or no stroke because of well developed collaterals. Conversely, the prognosis for those with hemodynamic impairment is poorer.1 Chronic occlusive lesion does not seem to represent a significant embolic source but threatens the patient with hemodynamic ischemia and infarct. In addition, patients with MCA occlusion may have disabling cognitive impairment, especially for those with bilateral diseases.5 For our two patients, the etiology of their recurrent TIAs was likely to be hemodynamic impairment from total MCA occlusion, arising from atherosclerotic stenosis and superimposed thrombosis based on angiographic findings. The optimal management of them was ...

Both the level of serum insulin and the adhesiveness of platelets are correlated with sucrose intake in men with peripheral vascular disease. These correlations do not exist in men who have no signs or symptoms of the disease, or of predisposing conditions such as hypertension.. The results support the suggestion of Szanto & Yudkin (1969) that an habitual high intake of sugar raises the insulin level in some individuals but not all, and that these individuals are susceptible to the effect of sucrose in producing occlusive arterial disease.. ...

OBJECTIVES: To evaluate the cost effectiveness of 40 mg simvastatin daily continued for life in people of different ages with differing risks of vascular disease. DESIGN: A model developed from a randomised trial was used to estimate lifetime risks of vascular events and costs of treatment and hospital admissions in the United Kingdom. SETTING: 69 hospitals in the UK. PARTICIPANTS: 20,536 men and women (aged 40-80) with coronary disease, other occlusive arterial disease, or diabetes. INTERVENTIONS: 40 mg simvastatin daily versus placebo for an average of 5 years. MAIN OUTCOME MEASURES: Cost effectiveness of 40 mg simvastatin daily expressed as additional cost per life year gained. Major vascular event defined as non-fatal myocardial infarction or death from coronary disease, any stroke, or revascularisation procedure. Results were extrapolated to younger and older age groups at lower risk of vascular disease than were studied directly, as well as to lifetime treatment. RESULTS: At the April 2005 UK
BACKGROUND: Throughout the usual LDL cholesterol range in Western populations, lower blood concentrations are associated with lower cardiovascular disease risk. In such populations, therefore, reducing LDL cholesterol may reduce the development of vascular disease, largely irrespective of initial cholesterol concentrations. METHODS: 20,536 UK adults (aged 40-80 years) with coronary disease, other occlusive arterial disease, or diabetes were randomly allocated to receive 40 mg simvastatin daily (average compliance: 85%) or matching placebo (average non-study statin use: 17%). Analyses are of the first occurrence of particular events, and compare all simvastatin-allocated versus all placebo-allocated participants. These intention-to-treat comparisons assess the effects of about two-thirds (85% minus 17%) taking a statin during the scheduled 5-year treatment period, which yielded an average difference in LDL cholesterol of 1.0 mmol/L (about two-thirds of the effect of actual use of 40 mg simvastatin

The prevalence of lower-extremity arterial occlusive disease (LEAOD), the progression of LEAOD, and the incidence of new LEAOD were determined by noninvasive method in 410 volunteers between the ages of 50 and 70 yr; 252 individuals had type II (non-insulindependent) diabetes, 158 were control subjects. LEAOD was monitored with the ankle/arm systolic blood pressure index in combination with Doppler arterial velocity waveform analysis. LEAODwas much more prevalent in the type II patients (22%, 55 of 252) than in thecontrol subjects (3%, 4 of 158) (P , .00001). The prevalence of risk factors for LEAOD was much higher in the type II patients, including elevated triglyceride, depressed high-density lipoprotein (HDL) cholesterol, hypertension, smoking, and elevated systolic blood pressure. In type II diabetic patients the incidence of new LEAOD over a 2-yr period (14%, 28 of 197) was lower than the incidence of LEAOD progression (87%, 45 of 52). Type II patients with LEAOD also had a high incidence ...
Purpose: Sarpogrelate hydrochloride, a selective 5-hydroxytryptamine 2A antagonist, is a widely used antiplatelet agent for the treatment of peripheral arterial disease (PAD). DP-R202 is a new sarpogrelate hydrochloride product with an improved dosage regimen compared with the agent in current use. The aim of this study was to compare the efficacy and safety profile of DP-R202 and Anplag* Tab in patients with PAD. Methods: This study was a 12-week, multicenter, randomized, double-blinded, active-controlled, parallel group comparative Phase III clinical trial. One hundred fifty-one volunteer patients with PAD were randomized to receive DP-R202 300 mg once daily or Anplag Table 100 mg TID for 12 weeks. The primary end point was a change in patient assessment of lower leg pain intensity with the use of a visual analog scale (VAS) after 12 weeks of treatment. Results after 4, 8, and 12 weeks of treatment were compared with baseline and between treatment groups, and all patients were assessed for ...

Although CT angiography (CTA) has demonstrated its efficacy as anon-invasive clinical alternative to cardiac angiography, there havebeen few studies examining its utility in the evaluation of peripheralarterial occlusive disease (PAOD). According to recent researchpublished in the American Journal of Roentgenology, CTA should be used in the management of PAOD.

Methods for treating total and partial occlusions employ a perfusion conduit which is penetrated through the occlusive material. Oxygenated blood or other medium is then perfused through the conduit in a controlled manner, preferably at a controlled pressure below the arterial pressure, to maintain oxygenation and relieve ischemia in tissue distal to the occlusion. In another aspect, interventional devices, such as stents or balloon catheters, are passed through the perfusion catheter to remove obstructions. Optionally, the occlusion may be treated while perfusion is maintained, typically by introducing a thrombolytic or other agent into the occlusive material using the perfusion conduit or by employing mechanical means to remove the obstruction. Such methods are particularly suitable for treating acute stroke to prevent damage to the cerebral tissue.
