肺血栓栓塞症(Pulmonary thromboembolism,PTE)首先于1989年由Lachnee所记载,是临床重危的并发症之一。本文就近年来的若干进展作一简述。PTE的发病概况美国每年约有50万人发生PTE,约五万人死于该病。Bomalaski则报道为60～75万/年,死亡数达15万/年。发生PTE得到及时治疗者的死亡率为8.3%,未治疗者为15～38%,生存者的栓塞复发率为20～50%。据尸检资料PTE的年发病率: Pulmonary thromboembolism (Pulmonary thromboembolism, PTE), first described by Lachnee in 1989, is one of the most clinically important complications. This article gives a brief account of some recent developments. PTE incidence profile Each year about 500,000 PTE occurs in the United States, about 50,000 deaths from the disease. Bomalaski reported between 60 and 750,000 per year, with a death toll of 150,000 per year. Mortality in those treated with PTE was 8.3%, in those without treatment 15% to 38%, and in those with survivors 20% to 50%. According to autopsy data PTE annual incidence:
