We studied 4 patients with bilateral carotid artery occlusion who suffered delayed TIAs in one of the occluded internal carotid or common carotid areas. Hemodynamic mechanisms were prominent in two patients, in head turning and orthostatic hypotension. In the other two cases, embolic phenomena through the homolateral external carotid collateral pathways were probable, because this artery (or th...

abstract introduction: anxiety is associated with a higher risk of cardiovascular disease. the present study aims to assess the extent of carotid artery atherosclerosis in patients with and without anxiety disorder. methods: in a cross-sectional study, two groups of participants with and without anxiety disorder (40 and 80 subjects, respectively) according to dsm-iv were selected from the psych...

background: the incidence of stroke is 2.1-5.2% in bypass surgery patients with a mortality of 0-38%. this study was designed to evaluate the incidence of significant carotid artery stenosis and its related risk factors in candidates for coronary artery bypass graft (cabg) surgery. methods: 1045 consecutive candidates for cabg underwent carotid artery doppler examination in a prospective study....

background: radial movement of the arterial wall is a well-known indicator of the mechanical properties of arteries in arterial disease examinations. in the present study, two different motion estimation methods, based on the block-matching and maximum-gradient algorithms, were examined to extract the radial displacement of the carotid artery wall. methods: each program was separately implement...

Aberrant right subclavian artery, the most common anatomic variant of aortic arch, occurs in 0.5% population. Symptoms generally result from compression esophagus and/or trachea as aberrant vessel passes posteriorly mediastinum. Treatment includes revascularizing artery carotid using a cervical approach combined with occluding origin thoracic aorta. We describe hybrid treatment for symptomatic ...

BACKGROUND Human anatomy texts in current use have very little precise information as to the frequency of variations in the bifurcation of the common carotid artery, and a clear description of the relation between external and internal carotid arteries as well as the variation of the origin of the ascending pharyngeal and superior thyroid arteries is limited. MATERIAL AND METHODS Sixty common...
