肺栓塞(PE)是内源性或外源性的栓子堵塞肺动脉及其分支引起的以肺循环和呼吸功能障碍为主的一系列临床和病理综合征。在临床诊治中,血栓栓子来源造成的PE相对较多见。血栓栓子的来源包括下肢深静脉、盆腔静脉、右心附壁血栓等。由于临床表现较为多样,缺乏特异性,PE的误诊漏诊率很高,未经治疗的PE死亡率极高[1]。妊娠肺栓塞是指孕产期内源性或外源性血栓栓子堵塞肺动脉或其分支引起肺循环障碍的临床和病理综合征。近年来,随着诊断水平的提高和对肺栓塞的认识的深入,
Pulmonary Embolism (PE) is a series of clinical and pathological syndromes characterized mainly by pulmonary circulation and respiratory dysfunction caused by embolization of the pulmonary artery and its branches with endogenous or exogenous emboli. In clinical diagnosis and treatment, the PE caused by thromboembolism is relatively common. Thromboembolic sources include deep veins of the lower extremities, pelvic veins, and right-sided mural thrombi. Due to the diversity of clinical manifestations and lack of specificity, the misdiagnosis rate of PE is very high, and the mortality rate of untreated PE is extremely high [1]. Pregnancy pulmonary embolism refers to the pregnancy or endogenous or exogenous thromboembolism blocking the pulmonary artery or its branches cause pulmonary circulation disorders clinical and pathological syndrome. In recent years, with the improvement of diagnostic level and understanding of pulmonary embolism,
