Abstract： 目的 利用99mTc-大颗粒聚合白蛋白(MAA)肺灌注显像(PPI)监测下肢创伤及手术后(LEPP)肺栓塞(PE)患者的疗效.方法 19例临床确诊的LEPP合并PE患者分别于溶栓治疗前、治疗2～4周后进行PPI;PPI图像上显示一个肺段灌注完全缺损记3分,缺损25%～75%记2分,＜25%记1分,无异常记0分,根据记分变化分析溶栓治疗前后临床改善情况.结果 19例患者溶栓治疗2～4周后临床症状完全消失10例、明显改善6例、有改善3例,治疗前(10.2±3.8)后(2.8±1.4)PPI记分有明显差异(t=7.75,P＜0.01).结论 PPI为一种准确、可靠的无创性评价肺血流改善的手段,对LEPP合并PE患者疗效观察具有重要的临床价值.
