数字减影血管造影在缺血性脑血管病检查及治疗中的价值

The value of DSA in ischemic cerebrovascular disease

目的探讨数字减影血管造影(DSA)在缺血性脑血管病检查及治疗中的价值。方法回顾性分析325例反复发作的短暂脑缺血发作或脑梗死患者的脑血管造影检查结果,结合临床症状及磁共振血管成像(MRA)进行对比。结果DSA未见明显异常18例,单纯颅外动脉狭窄163例,单纯颅内动脉狭窄76例,同时存在颅内外多发狭窄和(或)闭塞68例,83例接受了介入治疗。支架成形术后脑实质染色增加、循环时间缩短。结论全脑DSA检查是缺血性脑血管病诊断的"金标准",与MRA相比更能明确病变部位、形态、性质及侧枝循环情况,是介入干预前的必备手段,对评估支架成形术前术后血液动力学变化优于其他影像检查。

Objective To investigate the value treatment of ischemic cerebrovascular disease. Methods of digital subtraction angiography（DSA） in diagnosis and 325 patients with recurrent attacks transient ischemic attacks or cerebral infarction undergone DSA were reviewed and compare to MRA. Results In all cases, 18No abnormality seen, 163 extracalvarium arterioarctia, 76 intracalvarium arterioarctia, 68 exterior and interior cranium arterioarctia or obstruction. 83 undergone interventional therapy. After stent-assisted angioplasty,the stain of brain has increased and the cycle time has shorten. Conclusion DSA is gold standard in ischemic cerebrovascular disease, Compared to MRA, it can identify the region, shape, character of diseased and collateral circulation, it ＂s the necessarily method in prevcnient interventional therapy. In to evaluated the hemodynamic change of the pre-operative and the post-operative of stent-assisted angioplasty,DSA have an adventage than other exam.
