摘　　要：本文探讨应用CT肺动脉造影(CTPA)联合D-二聚体诊断急诊肺栓塞的价值。选取疑似肺栓塞患者108例为研究对象,均在行CTPA、D-二聚体检查。肺栓塞患者血清D-二聚体水平明显高于非肺栓塞患者(P<0.05);D-二聚体预测肺栓塞的ROC曲线下面积为0.921,P<0.05;D-二聚体≥2.50μg/mL患者CTPA肺栓塞检出率明显高于D-二聚体<2.50μg/mL患者(P<0.05);肺栓塞患者CPTA间接征象中,不规则形实变影、肺不张影级下腔静脉返流高于非肺栓塞患者(P<0.05);肺栓塞患者D-二聚体与CT肺动脉栓塞指数(CTI%)呈正相关(r=0.684,P<0.05)。CTPA联合D-二聚体检测在急诊肺栓塞诊断中有较好的应用价值,尤其在D-二聚体水平≥2.50μg/mL患者中CTPA肺栓塞检出率高。The purpose of this study was to investigate the value of CT pulmonary angiography(CTPA) combined with D-dimer in the diagnosis of emergency pulmonary embolism. 108 patients with suspected pulmonary embolism were selected, the CTPA and D-dimer were examined, the level of serum D-dimer in patients with pulmonary embolism was significantly higher than that in patients without pulmonary embolism(P<0.05). The area under the ROC curve of D-dimer in predicting pulmonary embolism was 0.921(P<0.05). The detection rate of CTPA pulmonary embolism in patients with D-dimer≥2.50 μg/mL was significantly higher than that in patients with D-dimer < 2.50 μg/mL(P<0.05). In the indirect signs of CPTA, the proportion of irregular consolidation, atelectasis and inferior vena cava reflux of pulmonary embolism patients were higher than those of non pulmonary embolism patients(P<0.05), D-dimer was positively correlated with CT pulmonary embolism index(CTI%)(r=0.684, P<0.05). CTPA combined with D-dimer detection has good application value in the diagnosis of emergency pulmonary embolism, especially in patients with D-dimer level ≥ 2.50 μg/mL, the detection rate of CTPA pulmonary embolism is high.
