伴脑动脉狭窄的症状性腔隙性脑梗死患者脑血管造影分析

目的分析伴脑供血动脉狭窄的症状性腔隙性脑梗死患者的全脑血管造影结果。方法选择经CT或MRI确诊的51例症状性腔隙性脑梗死患者,全部接受全脑血管造影检查,均存在脑供血动脉狭窄,观察统计病变血管的狭窄程度及闭塞血管的侧支代偿情况。结果全部患者均成功接受全脑血管造影,无严重并发症发生,狭窄程度：9例（17.65%）≤50%,12例（23.53%）50%～70%,14例（27.45%）71%～99%,16例（31.37%）闭塞。51例中,40例（78.43%）存在梗死相关病变血管。16例闭塞病例中,12例有侧支循环形成。结论对伴脑供血动脉狭窄的症状性腔隙性脑梗死患者行全脑血管造影具有较高的阳性率,梗死主要由前循环系统血管病变引起,观察血管病变程度及侧支代偿建立情况对疾病下一步治疗具有重要指导作用。

Analysis of cerebral angiography of symptomatic lacunar infarction accompanied with cerebral artery stenosis

Objective To analyze the results of cerebral angiography in patients of symptomatic lacunar infarction（LI）accompanied with cerebral artery stenosis.Methods A total of 51 patients with CT or MR diagnosed LI underwent cerebral angiography.The stenosis degree of vasculopathy and the collateral compensation to occlusive artery were analyzed.Results Cerebral angiography was performed successfully without serious complication on all the patients.The stenosis was ≤50% in 9 patients（17.65%）,50%—70% in 12 patients（23.53%）,71%—99% in 14 patients（27.45%）,and total occlusion was detected in 16 patients（31.37%）.Infarction correlated artery was found in 40 patients（78.43%）,while collateral compensation was noticed in 12 patients.Conclusion Cerebral angiography has high positive rate in patients of symptomatic lacunar infarction accompanied with cerebral artery stenosis.The development of infarction is mainly caused by cerebral artery of anterior circulation system.It is very important to guide therapeutics strategy through observing the degree of vasculopathy and the formation of collateral compensation.
