对我校30年用140例肺血栓栓塞病的临床与病理资料进行了分析,发现本病发病率高,并有近年增加趋势。探讨了肺血栓栓塞病的早期诊断。认为:注意易引起本病的各种基础疾病,突然发作、原因不明的呼吸频数,不明原因的发作性晕厥,PaO_2与PaCO_2同时降低及一过性心电图改变等是早期发现本病的重要线索。 Thirty years of my school with 140 cases of pulmonary thromboembolism clinical and pathological data were analyzed and found that the incidence of this disease is high and has increased in recent years.
