摘  要:目的 探讨中重度脑白质疏松(leukoaraiosis,LA)与前循环梗死静脉溶栓患者脑出血转化及预后的关系.方法 连续收集2014年1月至2017年3月于我院急诊科或神经内科(发病4.5h内)接受重组组织型纤溶酶原激活剂(rt-PA)静脉溶栓治疗的前循环梗死患者78例.所有患者均为首发脑梗死且溶栓后完善头颅MRI检查(包含DWI及FLAIR);根据Fazekas量表评分将其分为LA组和无LA组,比较两组间的一般资料及临床特征;观察患者90 d预后情况,并分析脑白质疏松对预后的影响.结果 在78例脑梗死患者中,合并LA者24例(30.8%),无LA者54例(69.2%).LA组中静脉溶栓后脑出血转化发生率为33.3%(8/24),无LA组为11.1% (6/54),差异有统计学意义(x2 =5.571,P=0.018);而症状性颅内出血发生率分别为16.7% (4/24)及5.6%(3/54),两组间差异无统计学意义(x2=2.304,P=0.129).LA组3个月内卒中的复发比例高于无LA组[20.8%(5/24)与5.6% (3/54)],但差异亦无统计学意义(x2=3.850,P=0.050);在肢体运动功能恢复[(92.3±3.4)分与(72.9±7.8)分;t=22.345,P<0.01]和90 d改良Rankin量表评分为0~2分的患者比例[83.3% (45/54)与50.0% (12/24),x2=9.383,P=0.002)方面,无LA组明显优于LA组.LA组患者的年龄[(73.7±6.7)岁与(61.3±10.6)岁,t=6.567,P=0.012]也明显高于无LA组.通过发病后90 d随访发现,在78例患者中,有预后良好者57例(73.1%),预后不良21例(26.9%),预后不良患者中死亡6例(7.7%).其中,预后不良患者合并LA[57.1%(12/21)与21.1% (12/57),x2=9.383,P=0.002]、存在陈旧性腔隙性脑梗死[66.7%(14/21)与35.1%(20/57),x2=6.224,P=0.013]以及3.0~4.5 h内溶栓的比例[71.4%(15/21)与38.6%(22/57),x2=6.634,P=0.010]更高,年龄[(72.8±7.9)岁与(61.5±11.7)岁,t=4.423,P=0.039]、闭塞部位血管管径[66.7%(14/21)与38.6%(22/57),x2=4.865,P=0.027]及梗�Objective To investigate the influence of moderate to severe leukoaraiosis (LA) on hemorrhagic transformation and prognosis of patients after intravenous recombinant tissue plasminogen activator thrombolysis for acute ischemic stroke and analyze influencing factors of the clinical prognosis.Methods We consecutively collected patients with acute infarct on anterior circulation (n =78) in Department of Neurology or Emergency of our hospital between January 2014 and March 2017,and all patients received intravenous thrombolysis therapy within the 4.5-hour time window.All patients processed brain MRI after intravenous thrombolysis therapy.According to the degree of LA,all subjects were classified into two groups;LA group (moderate to severe) vs no LA group (absent to mild).Clinical data were obtained and compared among patients with different grades of LA.Logistic regression analysis was used to confirm the relevant factors of prognosis 90 days after stroke.Results Among 78 enrolled patients,24 (30.8%) were classified as LA and 54 (69.2%) as no LA.In the group of LA,33.3% (8/24) patients conducted hemorrhagic transformation,whereas 11.1% (6/54) patients also underwent hemorrhagic transformation in the group of no LA.There was a significant difference between the two groups (x2 =5.571,P =0.018).But symptomatic intracranial hemorrhage accounted for 16.7% (4/24) and 5.6% (3/54) respectively in the two groups without significant difference (x2 =2.304,P =0.129).Three-month recurrence of stroke in the groups of LA and no LA was 20.8% (5/24) and 5.6% (3/54) respectively,also without significant difference between the two groups (x2 =3.850,P =0.050).Age ((73.7 ± 6.7)years vs (61.3 ± 10.6) years,t =6.567,P =0.012),90 d Fugl-Meyer Scale (FMS) score (92.3 ± 3.4 vs 72.9 ± 7.8,t =22.345,P 〈 0.01) and proportion of 90 d modified Rankin Scale score 0-2 (83.3%(45/54) vs 50.0% (12/24),x2 =9.383,P =0.002) were significantly different betwe
