Cerebral angiographic findings in 74 cerebral ischemic event patients

Objective To analyze the clinical data of cerebral digital subtraction angiography(DSA) of ischemic stroke patients.Methods Seventy-four cerebral ischemic event patients underwent highly selective DSA for observation of carotid arteries,vertebral arteries,and all intracranial arteries.The degree of stenosis,the locations and numbers of the arteries involved and the morphology of plaque or the stenosis were assessed.Results Angiography showed occlusion or stenosis of cerebral artery in 90.38% of the cerebral infarction patients,of them 31.91% were located in anterior circulation,17.02% in posterior circulation and 51.06% in both anterior and posterior circulations.Single vessel was involved in 23.40% and multiplie vessels were involved in 76.60%.In transient ischemic attack patients,81.82% had vascular lesions,of them 50.00% were located in anterior circulation,16.67% in posterior circulation and 33.33% in both anterior and posterior circulations.Single vessel was involved in 44.44% and multiple vessels were involved in 55.56%.The internal carotid arteries and middle cerebral arteries were most frequently involved in anterior circulation and the vertebral arteries were most frequently involved in the posterior circulation.Multiposition and multiple vessels involvement were common.Conclusion DSA can judge the prognosis and offer the evidence for formulating the plans of prevention and treatment of ischemic stroke.
