后循环缺血患者数字减影脑血管造影评价

目的利用数字减影脑血管造影方法观察后循环缺血患者脑血管的结构异常情况,比较后循环短暂性脑缺血发作患者与后循环脑梗死患者血管结构有无区别,探讨其临床价值。方法选择南京卒中登记系统中2004年1月至2008年5月所有后循环缺血并进行脑血管造影检查的397名患者,分析后循环缺血的临床资料及血管学资料。结果所有患者中,脑血管造影发现后循环血管病变304例,共435处血管。后循环短暂性脑缺血发作患者与后循环脑梗死患者后循环血管病变发生率无明显差异。在没有明确风险因素的78例患者中,椎动脉发育不全或后循环血管变异25例。结论后循环缺血脑血管造影检查阳性率较高,后循环短暂性脑缺血发作与后循环脑梗死患者血管异常率差异无显著性,在无风险因素的患者中以椎动脉发育不全或后循环血管变异为主。

Analysis of Cerebrovascular Anomalies in Posterior Circulation Ischemia Patients by Digital Subtraction Angiography

Aim To observe the vascular structures anomalies in posterior circulation ischemia patients by digital subtractions angiography (DSA), and to compare incidences of the posterior circulation vascular abnormalities of transient ischemic attack (TIA) patients with that of the posterior circulation ischemic infarction patients. Methods 397 patients were selected from Nanjing Stroke Registry Program from January 2004 to May 2008, and diagnosed as posterior circulation ischemia that had digital subtraction angiography examination at the same time. Results Posterior circulation vascular abnormalities were detected in 304 patients and 435 lesions, and there was no difference between the TIA and posterior circulation infarction patients (P>0.05). In the 78 patients without risk factor, there were 25 patients who had vertebral artery hypoplasia or posterior circulation variations. Conclusion The incidence of posterior circulation vascular anomalies in posterior circulation ischemia patients is high; there is no difference between the TIA and posterior circulation infarction patients. In patients without risk factor, the incidence of vertebral artery hypoplasia or posterior circulation variation is high.
