Carotid artery intraplaque hemorrhage and stenotic velocity.
BACKGROUND AND PURPOSE One of the proposed mechanisms for sudden expansion of a carotid bifurcation plaque is hemorrhage within the lesion. It has been postulated that the sudden increase in plaque size will acutely reduce blood flow to the ipsilateral hemisphere and induce either a transient ischemic attack or a stroke. In this study, the relation between peak systolic velocity at the site of ...
متن کاملCarotid Graft Replacement of the Stenotic Carotid Artery
It is well known connection between the stroke and diseases of carotid artery (stenosis, aneurysm, kinking). In the XIX century postmortem studies showed association of ischemic brain lesions and plaque formation in carotid bifurcation [1]. Later in 1937 Egaz Moniz performed first angiography while neurologists started to consider connection between carotid and brain lesions, and very soon idea...
متن کاملStenotic occlusive lesions of internal carotid artery in diabetic patients.
Diabetes deteriorates atherosclerotic changes in the arteries. The aim of the study was to assess the prevalence and localization of stenotic atherosclerotic lesions of the internal carotid artery (ICA) in patients with diabetes. A prospective analysis of angiography findings was carried out in 150 diabetic and 150 non-diabetic patients with symptoms of cerebral ischemia using double-blind angi...
متن کاملCarotid artery velocity patterns in normal and stenotic vessels.
Duplex scanning provides real time B-mode images of the carotid bifurcation vessels along with a single gate pulsed Doppler flow velocity detector. By using the B-mode output of the duplex system to measure the Doppler angle and spectrum analysis to measure the frequency content of the Doppler signal, instantaneous flow velocity can be calculated. Mean velocity at peak systole was calculated re...
متن کاملComputer Simulation of Stenotic Carotid Bifurcations Hemodynamic and Ultrasonography
The carotid sinus of the carotid artery (CA) bifurcation is one of the favored sites for the genesis and development of atherosclerotic lesions. The direct reason is carotid arteries bifurcation and stenoses may lead to great flow pattern change. Aim of this article is to investigate the effect of different eccentric stenosis of internal carotid artery on blood flow. The blood flow in artery is...
