肺栓塞(Pulmonary embolism,PE)是由于内源性或外源性栓子堵塞肺动脉或其分支引起肺循环障碍的临床和病理生理综合征。尽管已有抗凝溶栓及肺动脉血栓摘除术等较有效的治疗方法,但由于该病临床特征多样性,误诊和漏诊率很高,使针对性治疗不及时或缺如,导致目前PE的病死率达30％,因此早期诊断和及时治疗非常重要。我们回顾分析32例患者的临床资料,旨在提高对PE的认识。1 临床资料1.1 一般资料 32例患者均为我院1987年7月至1998年6月收治的住院患者,其中男15例,女17例,年龄20～79岁,平均年龄52岁。合并基础病情况如下:近期确诊有深静脉血栓14 Pulmonary embolism (PE) is a clinical and pathophysiological syndrome caused by endogenous or extrinsic emboli blocking the pulmonary artery or its branches causing pulmonary circulatory disorders. Although there are anticoagulant thrombectomy and pulmonary embolectomy and other more effective treatment, but because of the clinical features of the disease diversity, misdiagnosis and misdiagnosis rate is high, so that targeted treatment is not timely or absent, leading to the current PE death Rate of 30%, so early diagnosis and timely treatment is very important. We retrospectively analyzed the clinical data of 32 patients to improve our understanding of PE. 1 Clinical data 1.1 General Information 32 patients were hospitalized in our hospital from July 1987 to June 1998 admitted patients, including 15 males and 17 females, aged 20 to 79 years, mean age 52 years. Fundamental disease with the following conditions: the recent diagnosis of deep venous thrombosis 14
