BACKGROUND It is widely believed that carotid artery intima-media thickening represents an early marker for the development of atheroma. However, carotid intima-media thickening might also be expected to occur in response to an increased tensile stress and decreased wall shear stress which may accompany physical exercise. DESIGN, METHODS, AND RESULTS In order to test this hypothesis 24 athlet...

We investigated the effects of sequential and prolonged exposure to high and low wall shear stress on arterial remodeling using a rabbit arteriovenous fistula (AVF) model. Blood flow was increased by approximately 17-fold to 20-fold when the AVF was open, and returned to normal when the AVF was occluded. Repeated opening and closing of the AVF resulted in sequential exposure of the artery to hi...

The movement of the common carotid artery (CCA) vessel wall has been well accepted as one important indicator of atherosclerosis, but it is still one challenge to estimate the motion of vessel wall from ultrasound images. In this paper, a robust H∞ filter was incorporated with block matching (BM) method to estimate the motion of carotid arterial wall. The performance of our method was compared ...

A 50-year-old male presented with an extremely rare dorsal wall aneurysm of the internal carotid artery manifesting as intracerebral hemorrhage. Computed tomography demonstrated intracerebral hemorrhage on the frontal base. Magnetic resonance imaging clearly showed the hemorrhage was related to an aneurysm of the internal carotid artery. Cerebral angiography disclosed an elongated aneurysm of t...

introduction: doppler ultrasonography (dus) is the most preferable method for screening of carotid artery disease in patients undergoing cabg. the purpose of this study was to investigate the frequency of carotid artery disease and determine the relation between known risk factors of atherosclerosis and rate of carotid artery narrowing in order to identify high-risk groups among patients schedu...

A case of visual disturbance by embolization through the external carotid artery (ECA) after internal carotid artery (ICA) occlusion is reported. A 65-year-old female presented left ICA occlusion 14 years ago. She was admitted with acute deterioration of left visual acuity. Ophthalmologically, the retinal central artery was occluded. Cerebral angiography disclosed an irregular wall at the left ...

Background and Purpose—Carotid artery atherosclerosis is a strong predictor for future stroke. It is yet unclear whether the apolipoprotein E polymorphism (APOE) is related to atherosclerosis in the carotid arteries. The aim of the present study was to investigate the role of APOE in carotid artery atherosclerosis. Methods—A population-based cross-sectional study was performed on 5401 subjects....

Background: Lichen planus is a chronic inflammatory disease associated with an increased risk of subclinical atherosclerosis and cardiovascular diseases. This study aimed to evaluate patients with lichen planus using carotid Doppler ultrasound parameters.Methods: Forty patients with lichen planus and 40 controls were included in this study. Common carotid...

Introduction: Atherosclerosis has been shown to be a systemic disease frequently involving multiple vascular beds . Atherosclerotic diseases occurring in carotid arteries and thoracic aorta have been demonstrated to be associated with transient ischemic attack (TIA) and stroke . Recently, Mani et al [5] reported that both carotid artery and thoracic aorta showed greater plaque burden in patient...
