An Ultrasonographic Study of Carotid Artery Pathology in Ischaemic Stroke Patients

BACKGROUND of ischaemic strokes are due to extracranial carotid artery disease. Ultrasonography of the carotid arteries is easily , cost-effective noninvasive method of evaluation in preventing ischaemic strokes. evaluate the carotid artery pathology, and grade the stenotic lesions by ultrasonography in ischaemic stroke patients. AND METHODS 25 patients of clinically diagnosed cerebrovascular insufficiency, carotid and vertebral arteries on both sides were examined. site, size, echogenicity, luminal narrowing and velocity changes at the site of atherosclerotic plaque was recorded. The in percentages were compared and analysed. was the commonest presenting complaint. Among these 25 patients, 58% of them had atheromatous plaque. had a strong association with the development of plaque. 64% of these patients with atheromatous plaque were males a sex ratio of 1.8:1, 57% of plaques were found at carotid bifurcation predominantly on left side, 57% of these plaques significant stenosis and one had complete occlusion. Predominant type of these plaque were strongly echogenic with (52%), 35% of these patients had a PSV ratio of 2-4 and 14% >4. study showed atheromatous plaque changes with significant stenosis among cerebrovascular insufficiency patients. The were consistent with the other studies.
