Abstract: Objective To evaluate the predicting of early symptomatic intracraninal hemorrhage (SICH) afterlocal intra-arterial thrombolysis by nonconstrast CT and digital subtraction angiography (DSA)imaging in acute ischemic stroke.Methods Sixty cases of acute ischemic stroke performed local intra-arterial thrombolysis wereretrospective analysis their nonconstrast CT and DSA. They were divided into two group accordingto whether the SICH were diagnosed after operation. The preoperative nonconstrast CT and DSAimages of the two groups were compared.Results SICH were diagnosed in 5 cases. There were statistically significant difference betweenthe two group in old low density on nonconstrast CT, collateral flow supply and the vessel stenosison DSA.Conclusion Local intra-arterial thrombolysis in cerebral infarction in a comprehensive analysis ofpre-imaging can help predict the occurrence of SICH.
