肺动脉栓塞虽然不是一个独立的疾病,但在临床上却相当常见。在美国估计死于本病者,每年接近20万人。Moser在病理解剖中发现城市居民死亡者几乎2/3有肺栓塞。但由于本病缺乏特异的实验室诊断方法,生前常不易得到确诊。例如经解剖证实有肺栓塞者,80—90％生前未得到诊断。我国目前有关这 Although pulmonary embolism is not an independent disease, but clinically quite common. Nearly 200,000 people are estimated to die each year in the United States. Moser found in the pathological anatomy that almost 2/3 of urban dwellers had pulmonary embolism. However, due to the lack of specific laboratory diagnosis of this disease, often difficult to get diagnosed. For example, anatomical confirmed pulmonary embolism, 80-90% of his lifetime unrecognized.
