大动脉炎性脑缺血的脑血管造影特征分析

The angiographic features of cerebral isehemia due to Takayasu arteritis

目的探讨大动脉炎性脑缺血的脑血管造影特征。方法回顾性分析20例大动脉炎性脑缺血患者的病例资料及脑血管造影结果。脑血管造影资料由有经验的介入放射学医师按盲法对比进行分析，然后共同讨论并达成一致意见。结果20例中，经血管造影按Lupi-Herrera综合分型法Ⅰ型17例，Ⅲ型3例。主要受累动脉包括锁骨下动脉19例，颈动脉17例，椎动脉12例，头臂于6例。结论脑血管造影可准确、有效的评估大动脉炎性脑缺血患者的血管情况，有利于大动脉炎的诊断。

Objective To explore the angiographic features of c cerebral ischemia due to Takayasu arteritis. Methods The clinical data and angiographic findings of twenty patients with Takayasu rteritis were analyzed retrospectively. Two experienced radialogists read all the angiographic images of the patients with a double-blind method, then discussed together, and finally formed an unanimous interpretation. Resulta According to the Lupi-Herrera classification, 17 of 20 patients were type Ⅰ and the rest 3 were type Ⅲ on angiograms. The affected arteries mainly included subclavian artery （19 patients）, carotid artery （17 patients）, vertebral artery （12 patients）, and brachiocephalic trunk （6 patients）. Coneluaiana Cerebral angiography can accurately and effectively assess the vascular status in patients with cerebral ischemia due to Takayasu arteritis. It is beneficial in the diagnosis of Takayasu arteritis..
