Colour Doppler Evaluation of Extracranial Carotid Artery in Patients Presenting with Acute Ischemic Stroke and Correlation with Various Risk Factors

摘要

IntroductionStroke is defined as an abrupt onset of neurologic deficit due to vascular cause. It is one of the leading causes of mortality and morbidity all over the world making early diagnosis and treatment inevitable. Lesions of extra cranial carotid arteries are implicated in majority of cases of acute ischemic stroke. Carotid Doppler is a non-invasive imaging technique, with sensitivity approaching that of angiography. Computed Tomography (CT) plays a major role to assess the site and nature of the lesion in patients with acute ischemic stroke.
