Abstract: ObjectiveTo explore risk factors for different types of intracranial vascular narrow in patients with cerebral ischemic stroke based on Oxfordshire Community Stroke Project(OCSP)classification criteria. MethodsWe recruited 135 first hospitalization patients with cerebral ischemic stroke from March 2006 to February 2007 in the Second Affiliated Hospital of Harbin Medical University and all the patients were examined with transcranial Doppler ultrasound(TCD)and classified according to OCSP criteria.Logistic regression model was used to analyze the risk factors of intracranial vascular narrow. ResultsIntracranial vascular narrowing rate was 23.70% among the patients which was mainly middle cerebral artery stenosis.History of hypertension,history of diabetes,and total anterior circulation infarct(TACI)classified based OCSP criteria were the risk factors of intracranial vascular narrow for the patients. ConclusionCerebral ischemic stroke patients should pay more attention to the occurrence and development of high blood pressure and diabetes for the prevention of intracranial stenosis and the recurrence of ischemic stroke.
