肺血栓栓塞症误诊为支气管哮喘原因分析

目的提高对肺血栓栓塞症 ( pulmonarythromboembolism ,PTE)的认识 ,减少误诊。方法对 16例误诊为支气管哮喘的PTE进行回顾性分析。结果 16例均经影像学检查及D 二聚体测定确诊为PTE ,其中 4例经超声心动图、MRI、肺通气 /灌注扫描确诊为中央型肺栓塞 ;12例经双螺旋CT肺动脉造影确诊为周围型肺栓塞。结论周围型肺栓塞易误诊为支气管哮喘 ,因此 ,临床上应通过完善各项检查 ,综合分析病情 ,提高PTE和支气管哮喘的鉴别能力 ,以减少误诊发生。

Causal analysis on misdiagnosis of pulmonary thromboembolism as bronchial asthma

Objective To deepen our understanding of pulmonary thromboembolism (PTE) and to reduce misdiagnosis of it. Methods A retrospective analysis was conducted on 16 cases of PTE misdiagnosed as bronchial asthma. Results PTE was confirmed in these 16 patients with imaging examinations and detection of D-dimer.Among them,4 were diagnosed with central type of PTE through echocardiography,MRI and alveolar ventilationperfusion ratio;the other 12 cases were confirmed to have peripheral type of PTE with pulmonary angiograph under duoble-spiral CT. Conclusions Periphral type of PTE was easily misdiagnosed as bronchial asthma.Therefore,in clinical practice various tests and complete analysis of history should be performed so as to improve medical staff's capacity to differentiate PTE from bronchial asthma and thus to reduce misdiagnosis.
