Abstract

Comparative evaluation of Carotid Artery Doppler and Coronary CT angiogram as predictors of coronary artery disease (CAD) in patients with acute cerebrovascular accident (CVA). Materials and method: The present study was conducted in the Department of Medicine. The study participants were selected from patients presenting to casualty and outpatient departments with an acute cerebral event. The sample size was estimated to be 30 on the basis of the results of the pilot study.Coronary CT Angiography was done and data was collected using prescribed format. Correlation analysis was done between Carotid Doppler and Coronary CTA findings after complete collection of data. Review of all patients was done to describe the atherosclerotic changes in the vasculature. Results: There were 66.7% males and 33.3% females in the study population. The mean age of Males was 51.35±14.06 years, Females was 50.98±11.27 and Over-all study population was 50.48±11.29 years.The detection of Aneurysm was significantly more with CTA in comparison to MRA. The detection of aneurysm in Anterior Cerebral Artery (n=4) was missed on MRA as they were small in size of less than 3mm. One case of stenosis of ICA was missed on MRA having non-significant stenosis. Conclusion: The findings of this study demonstrate that computed tomography angiography is more accurate than diagnostic ultrasound in determining whether or not there is stenosis of the cervical arteries in either the internal carotid or vertebral arteries.
