Carotid Doppler and lipid profile findings in ischemic stroke patients--a hospital based study.

A prospective study was carried out during 2010 - 2011 in the Department of Radiology & Imaging of Nepal Medical College and Teaching Hospital, Jorpati, Kathmandu and Om Hospital and Research Centre, Chabahil, Kathmandu in which a total of 45 patients with clinically and CT scan diagnosed ischaemic cerebrovascular accident (CVA) underwent carotid Doppler study. During the hospital stay these patients also underwent lipid profile estimation to see for presence or absence of hyperlipidemia. Of these 45 patients, CT scan showed left middle cerebral artery (MCA) infarctions in 12, right MCA infarction in 12, lacunar infarctions in 10, watershed territory infarction in 4, posterior circulation infarction in 1 and venous infarction in 1 patient. Carotid Doppler study showed more than 50% stenosis in 31 patients. Among these 31 patients, 28 had hyperlipidemia where as blood cholesterol and triglyceride values in 3 patients were normal. The present study like several other studies done in the past showed association between carotid stenosis and hyperlipidemia, leading to CVA.
