Duplex Study of Carotid Artery in Patients With Ischemic Stroke

Abstract

Brief Description of the Purpose of the StudyTo determine the frequency and characteristics of carotid artery stenosis in acute ischemic stroke patients and to assess the significance of common risk factors for carotid stenosis in these patientsMethodsIt was cross-section observational study in one hundred hospital admitted patients with acute ischemic stroke . Doppler ultrasound was performed during the hospitalization to find out the degree of carotid artery stenosis.Main ResultsOut of one hundred (100) patients, eighty (80%) were males and twenty were (20%) were females. The patients were dividing into two groups with and without carotid stenosis. Less than 50% carotid artery stenosis (insignificant stenosis) was seen in 40% (n=40) cases and significant stenosis was seen in 60% (n=60) patients. Overall 86% (n= 46) out of 60 patients were found have carotid artery stenosis on the ipsilateral side corresponding to the ischemic lesion. And 19% (n=11) had stenosis on the contra lateral side as well. Degree of stenosis was mild (50% stenosis) in 12% (n=7) patients, moderate (51-69%) stenosis in 50% (n= 30) patients and severe (>70%) stenosis in twenty (n=33%) patients . Near total occlusion was seen in three (5%) patients. The presence of stenosis was significantly correlated with older age and the presence of multiple risk factorsImportance of the ConclusionsDoppler studies are recommended for the high risk patients for the primary as well as secondary prevention of ischemic stroke Brief Description of the Purpose of the StudyTo determine the frequency and characteristics of carotid artery stenosis in acute ischemic stroke patients and to assess the significance of common risk factors for carotid stenosis in these patients To determine the frequency and characteristics of carotid artery stenosis in acute ischemic stroke patients and to assess the significance of common risk factors for carotid stenosis in these patients MethodsIt was cross-section observational study in one hundred hospital admitted patients with acute ischemic stroke .
