肺血栓栓塞症(PTE)为来自静脉系统或右心的血栓阻塞肺动脉或其分支所致疾病,以肺循环和呼吸功能障碍为其主要临床和病理生理特征[1]。严重者可引起急性右心室扩张或右心衰竭。其病症轻重与栓子大小、栓塞范围及原有心肺疾病的代偿能力密切相关。PTE的诊断都是非特异性的和不敏
Pulmonary thromboembolism (PTE) is a disorder caused by clogged pulmonary arteries or its branches from the venous system or right heart.

The severity of the disease is closely related to the size of the embolus, the scope of embolism and the compensatory capacity of the original cardiopulmonary diseases. The diagnosis of PTE is nonspecific and insensitive
