If diagnosis of chronic thromboses of pulmonary arteries is usually easy at the stage of confirmed chronic pulmonary heart, it is not so when dysponea is the only symptom of the disease. The authors report 30 cases of chronic thrombosis and remark that if respiratory alkalosis is very frequent, hipoxemia is often missing. On the other hand they observe 27 times out of 28 an increase of CO2 alveoloarterial difference; measuring the CO2 difference appears a safe and reliable test for detecting chronic thrombosis. It should take place in every systematic complete examination of unexplained dyspnoea.
如果慢性肺动脉血栓形成在确诊慢性肺心病阶段通常易于诊断，那么当呼吸困难是该疾病的唯一症状时则并非如此。作者报告了30例慢性血栓形成病例，并指出如果呼吸性碱中毒非常常见，低氧血症往往不存在。另一方面，他们在28次观察中有27次发现肺泡动脉二氧化碳分压差增加；测量二氧化碳分压差似乎是检测慢性血栓形成的一种安全可靠的方法。在对不明原因的呼吸困难进行的每一次系统全面检查中都应进行此项检查。
