【摘要】 目的探究与分析肺动脉血栓栓塞猝死的病因及临床病理学特点。方法选取自2010年3月~2015年3月作者收集本地区由肺动脉栓塞引起的猝死患者56例,回顾性分析引起肺动脉栓塞猝死的诱发因素以及肺动脉栓塞的栓塞部位。结果肺动脉栓塞可由多种因素诱发引起,其中以骨折等外科手术患者以及长期卧床患者发生肺动脉栓塞的发病率最高,发病率分别为33.9%、32.1%;其他心肺疾病以及高龄因素同时具有肺动脉栓塞猝死的风险,发病率分别为28.6%、5.4%。肺动脉栓塞部位主要位于肺动脉主干及肺动脉分支处,肺动脉总干发病率为32.1%,双侧肺动脉分支的发病率为33.9%,左、肺动脉分支的发病率分别为21.5%和12.5%。结论肺动脉栓塞可由多种因素引起,明确肺动脉栓塞的诱发因素、栓子来源、临近事件以及病理学特点,对预防肺动脉栓塞猝死、降低患者病死率具有价值。更多还原

【Abstract】 Objective To explore and analyze the cause of the sudden death of pulmonary thromboembolism and clinicopathological features. Methods Our hospital in March 2014 to 2015, three menstrual forensic center proved by the sudden death in patients with pulmonary embolism caused 56 cases retrospectively analyzed the predisposing factors causing pulmonary embolism and sudden death from pulmonary embolism embolization. Results Pulmonary embolism induced by a variety of factors caused the occurrence of fractures among surgical patients and bedridden patients the highest incidence of pulmonary embolism, the incidence rate was 33.9%, 32.1% respectively, other cardiovascular diseases and elderly factor also has pulmonary embolism sudden death risk, the incidence rate was 28.6%, 5.4%, respectively. Pulmonary embolism sites are mainly located in the main pulmonary artery and pulmonary artery branches, and pulmonary artery incidence rate of 32.1%, the incidence of bilateral pulmonary artery was 33.9% of the left, the incidence of pulmonary artery were 21.5% and 12.5%, respectively. Conclusion Pulmonary embolism can be caused by many factors, predisposing factors clearly pulmonary embolism and pathological features of pulmonary embolism prevention of sudden death and reduce mortality is of great significance.更多还原
