早期肺栓塞的CT诊断及临床意义分析

Analysis of CT Diagnosis and Clinical Significance of Early Pulmonary Embolism

目的探索早期肺栓塞的CT诊断及临床意义。方法选取2014年5月—2015年5月期间收治112例疑似肺栓塞患者为此次研究对象,所有患者在实验室检查基础上(血气分析和血浆D-Dimer)进行CT诊断。结果 CT诊断在早期肺栓塞患者中的灵敏性、特异性、漏诊率、误诊率分别为96.97%、97.83%、3.03%、2.17%,对右肺主动脉栓塞诊断正确率为96.43%,对左肺动脉栓塞诊断正确率为100.00%,对双侧肺主动脉栓塞诊断正确率为95.45%。同时该次确诊为肺栓塞的66例患者,其中10例患者为轨道征,24例患者为完全堵塞,32例患者为部分性充盈缺损。结论 CT诊断在早期肺栓塞患者中具有一定的诊断意义。

Objective To explore the CT diagnosis and clinical significance of early pulmonary embolism. Methods 112 cases of patients suspected with pulmonary embolism admitted and treated from May 2014 to May 2015 were selected as the research objects and given the CT diagnosis on the basis of the laboratory examination（blood gas analysis and plasma D-Dimer）. Results The sensitivity, speci-ficity, missed diagnosis rate and misdiagnosis rate of CT diagnosis in the early pulmonary embolism were respectively 96.97%,97.83%,3.03%,2.17%, and the accurate rate in diagnosis of right pulmonary embolism, left pulmonary embolism and bilateral pulmonary em-bolism was respectively 96.43%, 100.00% and 95.45%, at the same time, in the 66 cases of patients with pulmonary embolism, there were 10 cases with tram-track sign, 24 cases with complete plugging and 32 cases with partial filling-defect. Conclusion CT diagnosis for patients with early pulmonary embolism is of a certain diagnosis significance.
