Abstract：Objective To assess the value of computed tomographic angiography(CTA)in the diagnosis of posterior circulation ischemia(PCI)by analyzing the results of CTA.Methods CTA were performed in 120 patients with PCI.The locations and numbers of the arteries were observed,and the degree of stenosis were assessed.Results Of the 120 cases,100 cases (83.3％)were with cerebrovascular lesions,including 16 cases (13.4％)of anterior circulation lesions,40 cases (33.3％)of posterior circulation lesions and 44 cases (36.7％)with both anterior and posterior circulation lesions.In all patients,there were 20 cases (16.7％)without abnormal blood vessel and 63 cases (52.5％)with two or more lesions.Conclusion CTA is a simple,quick and reliable examine method,and provides reliable,objective and practical imaging information for guiding surgery.
