Abstract

Objectives: To determine the frequency of carotid artery stenosis in ischemic stroke patients by Doppler ultrasonography.
Material and Methods: This study was conducted in Department of Diagnostic radiology in PNS Shifa, Karachi. Study
design was cross sectional descriptive and the duration of study was 6 months in which 131 patients were observed
by using population proportion at 21%, with confidence level of 95% and absolute precision of 7%. Moreover non
probability purposive sampling was used for sample collection.
Results: In this study, mean age was 55 years with ±1.26 standard deviation. Among 131 patients, 56% had carotid
artery stenosis while 44% patients didn’t have carotid artery stenosis.
Conclusion: The frequency of carotid artery stenosis as measured by Doppler ultrasound inpatients with ischemic
stroke is 56%. We can advise Carotid Doppler Ultrasonography in all ischemic stroke patients which will ultimately help
in planning future management (medical and / surgical) for further cerebrovascular accidents avoidance.

Keywords: Carotid artery stenosis, ischemic stroke, Transient ischemic attacks (TIA).
