摘要(Abstract)：

目的探讨急性脑梗死患者溶栓治疗后出血性转化(hemorrhagic transformation,HT)的危险因素以及继发HT患者的溶栓后并发症。方法回顾性分析62例经静脉溶栓治疗的急性脑梗死患者的临床资料,结合文献选择溶栓后继发HT的危险因素,包括年龄、性别、高血压、糖尿病、心功能不全史、脑卒中史、有无早期CT缺血改变、是否大面积脑梗死、是否心源性脑栓塞、发病至溶栓时间、溶栓药物、溶栓前NIHSS评分、溶栓前血糖水平、溶栓后3d内最低纤维蛋白原水平、血小板计数、肌酐水平等进行分析,对单因素分析法发现有统计学差异的危险因素进一步行Logistic回归分析。结果单因素分析发现,与无HT组相比,继发HT组年龄较大(P<0.01),溶栓前血糖水平(P<0.05)、溶栓后6h和12h的收缩压和舒张压较高(均P<0.05),大面积脑梗死发病至溶栓时间>3h、有早期CT缺血改变的患者比例高(均P<0.05)。Logistic多因素回归分析发现高龄(OR:1.129,P<0.05)、溶栓时间>3h(OR:2.592,P<0.05)、早期CT有缺血改变(OR:1.728,P<0.05)是继发HT的危险因素。继发HT组出现颅外出血并发症(52.2%vs 20.5%,χ2=6.637,P<0.05)、重度脑水肿(30.4%vs 5.1%,χ2=5.567,P<0.05)和脑疝形成(26.1%vs 2.6%,P<0.05)的比例更高。结论急性脑梗死患者静脉溶栓后HT的发生率高,高龄、发病至溶栓时间>3h和早期CT缺血改变是HT的危险因素。
