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