| 摘 要： | 目的 评估Qanadli等提出的CT阻塞指数在定量分析肺动脉栓塞(pulmonary embolism,PE)患者治疗效果中的价值.资料与方法 经多层螺旋CT血管成像(CTA)确诊、经溶栓或(及)抗凝治疗并治疗后以CTA随访的患者55例,随访时间为1-6周.治疗前后采用Qanadli栓塞指数评价PE程度,并采用Spearman等级相关系数评价其与临床指征(血氧饱和度及肺动脉压)恢复的相关性.结果 55例患者中,51例经溶栓或(及)抗凝治疗后临床指征明显改善,血氧饱和度由(83.52±4.461)%上升到(94.76±3.532)% (P <0.001),肺动脉压力由(31.17±5.892) mmHg(1mmHg=0.133kPa)下降至(19.83±4.804) mmHg (P<0.001);Qanadli栓塞指数从治疗前的(45.09±18.22)%降至治疗后的(10.86±10.29)%(P<0.001).4例临床指征改善不明显,Qanadli栓塞指数治疗前后差异无显著统计学意义(P=0.080).治疗前后Qanadli栓塞指数与血氧饱和度、肺动脉压力的差异度均存在良好相关性(r值分别为0.934,0.813 ).结论 Qanadli栓塞指数可准确用于PE治疗效果的定量评估,对临床治疗方案的制定有指导作用.

| Abstract: | Objective To quantitively evaluate the value of computed tomography(CT)obstruction index described by Qanadli et al in monitoring the effect of pulmonary embolism(PE)treated by thrombolysis and(or) anticoagulation.Materials and Methods Fifty-five consecutive patient with PE by computed tomography angiography(CTA)at the initial time(T0)were selected.All patients were treated with thrombolysis and(or)anticoagulation.CTA was performed again as the follow-up evaluation(T1)with the mean interval time 1-6 weeks a... |
