Abstract :

Cereovascular accident is a neurological emergency with the cases of stroke accounting for approximately 9 to 30% of all the neurological admissions. Trans-cranial Doppler and Carotid Doppler imaging play an important role in the study of flow parameters in the intracranial and extracranial blood vessels respectively. Plaque characteristics and percentage stenosis can be detected. Ultrasound of extra-cranial cereal circulation is used predominantly in assessment of patients with symptoms, which might arise from disease in carotid arteries. Computed tomography was carried out in 100 patients clinically suspected of having stroke. Carotid Doppler was carried out in all the patients diagnosed of having stroke or normal ( but had signs and symptoms of Stroke ) on computed tomography. We found that Doppler Ultrasound is an easy , readily available , cost effective technique with good technical efficiency. Atherosclerotic plaques are a common lesion in patients of stroke. Hypoechoic plaques have a great predictive value for development of large vessel stroke. Severity of stenosis of the extra cranial carotid Doppler has significant association with large vessel infarcts and has no association with lacunar infarcts and Hemorrhagic stroke, the etiology of which could some thing different. Thus every patient presenting with cereovascular symptom must undergo complete color duplex US examination of the carotid arteries, this will guide in selection of treatment modalities and will help in assessing the follow up of the disease and evaluating the effectiveness of treatment.
