vertebrobasilar insufficiency is the cause of cerebrovascular accidents in 20% of cases. there are few reports regarding spectral doppler indices (sdis) of vertebral arteries (vas) normal blood flow. the objective of this study was to provide basic reference data about sdis of vas normal blood flow separately and in comparison with internal carotid arteries (icas) and common carotid arteries (c...

 Introduction: Prevalence of stroke following coronary artery bypass graft surgery (CABG) is % 2.1-5.2 and associated with high mortality. The purpose of this study was to investigate the prevalence of carotid artery disease in patients undergoing CABG surgery.  Methods: This cross-sectional study was performed in the years 2010-2011 on 192 patients who underwent open heart surgery (CABG) in...

BACKGROUND Directed ultrasonic screening for carotid stenosis is cost-effective in populations with > 5% prevalence of the diagnosis. Occasionally, calcifications in the area of the carotid arteries are incidentally detected on odontological panoramic radiographs. We aimed to determine if directed screening for carotid stenosis with ultrasound is indicated in individuals with such calcification...

BACKGROUND It is recognized that complicated plaque largely accounts for the morbidity and mortality from atherosclerosis. Ideally, investigation of symptomatic and asymptomatic patients would identify atheromatous plaques independently of stenosis. We have previously shown that a magnetic resonance direct thrombus imaging (MRDTI) technique demonstrates complicated atheroma as high signal withi...

results in all groups ischemic changes were apparently observed in hippocampus ca1 neurons. in two-vessel occlusion model, after 3 and 24 hours of reperfusions, ischemic cells accounted for 14.9% and 23.2%, respectively. in four-vessel occlusion model, after 3 and 24 hours of reperfusions, ischemic cells accounted for 7.6% and 44.9% (p < 0.0001), respectively. background an appropriate animal m...

BACKGROUND AND PURPOSE The purpose of this study was to determine whether significant atherosclerotic disease in the carotid arteries predicts significant atherosclerotic disease in the coronary arteries, vertebral arteries, or aorta in patients with symptoms of acute ischemic stroke. METHODS Atherosclerotic disease was imaged using CT angiography in a prospective study of 120 consecutive pat...

Atherosclerosis manifests as a systemic disease with near global involvement of the named segments of the arterial tree. Acute thrombotic arterial occlusion, however, is not equally distributed. To evaluate intra-individual regional differences in arterial thrombogenicity, we compared (111)In-platelet deposition in porcine carotid and femoral arteries after a standardized crush injury. Within t...

BACKGROUND AND PURPOSE Information about the expression of atherosclerosis in different arteries is important. The impact of cardiovascular risk factors is artery-related, and the assessment of arterial structure and function in peripheral arteries are increasingly used as surrogate markers for coronary atherosclerosis and the risk of developing heart attack. METHODS In an autopsy study, we a...
