目的探讨全脑数字减影全脑血管造影(DSA)在缺血性脑血管病诊断中的应用价值。方法分析73例缺血性脑血管病行全脑DSA检查的诊断情况及安全性,观察其脑动脉血管颅内、外血管有无狭窄、狭窄程度及侧支循环情况。结果73例中发现66例有血管狭窄(90.4%),7例正常(9.6%),颅内段狭窄占35.6%,颅外段狭窄占54.8%;所有受检查者未发生明显的并发症及永久性神经功能缺损。结论全脑DSA可以确定缺血性脑血管病是否存在血管狭窄、狭窄程度及侧支循环代偿情况,对缺血性脑血管病治疗方案的选择起着重要的作用。
Objective To investigate the value of digital subtraction whole brain angiography (DSA) in the diagnosis of ischemic cerebrovascular disease. Methods The diagnosis and safety of DSA in 73 patients with ischemic cerebrovascular disease were analyzed. The cerebral blood vessels in the cerebral artery were observed for stenosis, stenosis and collateral circulation. Results Of the 73 cases, 66 cases had vascular stenosis (90.4%), 7 cases were normal (9.6%), 35.6% were intracranial stenosis and 54.8% were extracranial stenosis. No obvious complication was found in all subjects Permanent neurological deficit. Conclusion Whole-brain DSA can determine the existence of vascular stenosis, stenosis and collateral circulation compensatory status in ischemic cerebrovascular disease, which plays an important role in the treatment of ischemic cerebrovascular disease.
