摘　　要：目的:探讨急性缺血性卒中患者早期进行磁共振血管造影(magnetic resonance angiography,MRA)检查的意义。方法:依据血管病变将145例急性缺血性卒中患者分为2组:大血管闭塞组(n=83)和无大血管闭塞组(n=62)。采用Rankin量表(modified Rankin scale,mRS)评分评价患者的神经功能,比较2组的预后。结果:第3个月和第6个月随访时,大血管闭塞组患者mRS评分显著高于无大血管闭塞组;无大血管闭塞组mRS 0～2分患者所占比例均显著高于大血管闭塞组患者,分别为82.26%(51/62)比28.92%(24/83)和83.33%(50/60)比28.21%(22/78),差异具有统计学意义(P<0.005)。结论:急性缺血性卒中患者早期行MRA检查具有重要意义,可在一定程度上评估患者预后。Objective：To estimate the importance of early magnetic resonance angiography （MRA） examination in the patients with acute ischemic stroke. Methods： A total of 145 patients with acute ischemic stroke were divided into the large-vessel occlu- sion group and no large-vessel occlusion group according to the severity of the vascular lesions. Modified Rankin Scale（mRS） was used to assess the outcome after stroke. The prognosis of the two groups were compared. Results： The ratios of mRS 0 - 2 in no large-vessel occlusion group were significantly higher than those in large-vessel occlusion group at both three months and six months of the follow-up period[- 82.26% （51/62） vs. 28.92% （24/83） and 83.33% （50/60） vs. 28.21% （22/78）, respectively]. Conclusions： MRA inspection should be done as early as possible in patients with acute ischemie stroke, mRS is helpful to evaluate the prognosis of patients with acute ischemic stroke.
