Abstract
Aims and Objectives: Cerebral ischemic stroke is life-threatening and debilitating neurological disease, it is the third leading cause of death in the world. Studies have shown that there is a close relationship between carotid artery stenosis and ischemic cerebral vascular disease. Doppler study is valuable to assess the cause, location, extent and severity of carotid artery disease. The gray scale imaging provides information about the location. By combining the gray scale findings with colour Doppler characteristics, severity of stenosis is obtained. This study is done to assess the carotid arteries with the help of colour Doppler sonography and to correlate with CT findings of cerebrovascular accidents. There has been a recent proliferation of methods of assessing the extracranial circulation, including non-invasive techniques, such as the carotid Doppler ultrasound examination. Asymptomatic cerebral emboli can be detected using carotid Doppler ultrasound. These embolic signals have potential as a marker of stroke risk. Materials and Methods: The prospective study was carried out on 75 patients using Philips HD7XE ultrasound machine over a period of 12 months in the Radiology department of Maharjah’s Institute of Medical Sciences and correlated with Ge Dual Slice Ct Scan Unit. The data gathered included peak systolic velocity of common carotid artery (CCA) and internal carotid artery (ICA), velocity ratios between CCA and ICA and plaque characteristics as seen on real-time imaging. Results: The highest incidence of stroke was found in the male population in the age group of 60–69 years. Hypertension followed by smoking were considered as potent risk factors. Most of the plaques were located at the bifurcation and majority of them were echogenic.Out of 75 patients, 16 patients showed significant stenosis (>60%). Atherosclerotic plaques were seen in 57 patients (76%). Conclusion: Colour Doppler examination is an economic, safe, reproducible, and less time-consuming method of demonstrating the cause of cerebrovascular insufficiency in extracranial carotid artery system.
