【摘要】 目的利用数字减影血管造影方法(digital subtraction angiography,DSA)观察中枢性眩晕患者脑血管的形态变化,指导该病的临床诊断和治疗。资料与方法对临床拟诊断为中枢性眩晕的126例患者进行全脑血管造影检查,分析血管形态异常的类型、分布及意义。结果 126例中枢性眩晕患者中84例造影存在异常,单纯前循环病变占11.9%,单纯后循环病变占81%,前后循环同时存在异常者占7.1%。结论后循环血管病变可能是中枢性眩晕的主要病因,高脂血症和高血压是最主要的危险因素。更多还原

【Abstract】 Purpose To investigate the morphological changes of cerebral blood vessels by digital subtraction angiography (DSA) in patients with central vertigo, so as to provide references for diagnosis and treatment. Materials and Methods Total of 126 patients suffering from central vertigo were performed cerebral angiography. The types, proportion, and distribution of the cerebrovascular abnormalities were observed and analyzed. Results Of the 126 patients with central vertigo, cerebrovascular abnormalities were found in 91 cases, including 11.9% of anterior circulation abnormalities, 81% of posterior circulation abnormalities and 7.1% of both. Conclusion The posterior circulation stenosis or abnormalities might be the major reasons for central vertigo, hyperlipidemia and hypertension are the main risk factors.更多还原
