Angiographic findings in 48 cases of ischemic stroke

Objective To evaluate the frequency and localization of the involved arteries in ischemic stroke.by cerebral vascular angiography.Methods The patients suffered from ischemic stroke 4-30points of NIHSS and cerebral hemorrhage should be excluded by CT scan.All patients tested by TCD and color Doppler Ultrasound suspected arteries stenosis.All subjects underwent high selective angiographies for the observation of aorta,carotid arteries,vertebral,and all the intracranial arteries.The degree of stenosis ,the localization and numbers of the arteries involved and the morphology of plague or the stenosis were assessed.Results Angiography showed occlusive findings of cerebral arteries in 75.5% of the patients,among them 76% were located in anterior circulation and 24% were located in posterior.Additional 9 asymptomatic occlusive were found.Angiograms were normal in 6%.The internal carotid and middle cerebral arteries are most frequently involved in this series.The vertebral arteries were the most commonly involved in the posterior circulation.5 cases of Moyamoya 's disease.2 cases of Cerebral Vascular Malformations.Conclusion Most of patients with ischemic stroke were documented with definitive occlusion of cerebral arteries,The options of treatment should be based on the morphology of the involved arteries.interventional neuroradiology was useful for cerebrovascular disease.
