摘要
目的 提高临床医生对慢性阻塞性肺疾病（COPD）合并肺血栓栓塞症（PTE）的认识。方法 分析2例COPD合并PTE的临床特点，并复习相关文献。结果 2例COPD合并PTE患者临床表现以呼吸困难为突出表现，咳嗽、咳痰较轻，肺部缺乏啰音。动脉血气分析均有低氧血症，二氧化碳分压正常，其中1例二氧化碳分压较前下降。2例均经CT肺动脉造影确诊PTE。结论 缺乏感染征象、呼吸困难突出、二氧化碳分压较前降低是诊断COPD合并PTE的重要线索，CT肺动脉造影是确诊的重要技术之一。
Objective To enhance the knowledge of pulmonary embolism in the patients with chronic obstructive pulmonary disease （COPD）, two cases of these disorders were reported and related literature was reviewed. Methods The clinical data of two patients with both COPD and pulmonary embolism were analyzed. Results Both ,patients experienced significant dyspnea, mild cough and lack of crackles. The patients also had hypoxemia and one of them had a decrease of arterial partial pressure of carbon dioxide （PaCO2）. The diagnosis of pulmonary embolism was based on computed tomography pulmonary angiography. Conclusions The lack of symptoms and signs of infection in lungs, significant dyspnea, and decrease of PaCO2 hint the pulmonary embolism in the patients with COPD. Computed tomography pulmonary angiography is one of the diagnostic techniques.
