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...

Introduction: In this study, a computer analysis method based on a block matching algorithm is presented to extract the longitudinal movement of the carotid artery wall using consecutive ultrasonic images. A window (block) is selected as the reference block in the first frame and the most similar block to the reference one is found in the subsequent frames. Material and Methods: The program was...

Naturally occurring collatera l pathways con necting the external carotid artery branches and the intracran ial cerebral circulation are well recognized and have been demonstrated anatomically, angiographically, and physiologically by vari­ ous flow detection devices. Under normal c ircumstances, all internal carotid artery blood flow is direc ted intracranially, and flow through the co ll ater...

background and aims. this study was designed to evaluate the prevalence of calcified carotid artery in 50 year-old and older postmenopausal dental outpatients for early diagnosis of individuals at risk of stroke. materials and methods. this is a descriptive study of 200 panoramic radiographs. these radiographs included postmenopausal women referring to the department of oral medicine at shahid ...

Carotid artery stenosis is a notable cause of ocular ischemic disease. To analyze the ocular ischemic diseases caused by carotid artery stenosis and to seek effective treatment, a retrospective review of 182 patients with carotid artery stenosis was performed. These patients were administered medical treatment, carotid artery stenting (CAS) or carotid endarterectomy (CEA) and the curative effec...

Hypertension, diabetes, and hypercholesterolemia are characterized by a reduction in arterial distensibility and by accelerated atherosclerosis. Whether arterial stiffening is an inherent feature of these conditions or just the consequence of the atherosclerotic clinical or subclinical lesions is not known, however. Our aim was to obtain information on this issue by directly measuring, in human...

INTRODUCTION Branches from the cervical portion of the internal carotid artery are rare. In most cases, atherosclerotic stenosis is found at the bifurcation of the internal and external carotid arteries. However, when associated with atherosclerotic carotid artery disease, the origin of the rare branches arising from the internal carotid artery can be another site of stenosis. This report descr...

background common carotid artery (cca) ultrasound with measurement of intima-media thickness (imt) is a safe and noninvasive technique for assessing subclinical atherosclerosis and determining cardiovascular risks. moreover, the pattern of wall thickening in the brachial artery (ba) is rather diffuse compared to the carotid artery and may be a more sensitive indicator of long-term systemic expo...

Objective: We report the “sheath pull-through technique” for stenting of common carotid artery stenosis (CCAS).

Objective: We herein report two cases of transient cerebral vasoconstriction after carotid artery stenting (CAS).
