【摘要】 目的总结不明原因猝死案例的流行病学及法医病理检验特点,为探明其死因提供依据和线索。方法回顾分析发生于云南省的81例不明原因猝死案例的年龄、性别、死亡时状态等流行病学特征以及解剖检验和组织学检验结果。结果 81例不明原因猝死中7例为聚集性不明原因猝死,74例为散发性不明原因猝死。聚集性不明原因猝死发生具有时间、空间和家庭聚集性,死亡时清醒状态较多。散发性不明原因猝死以男性较多见,死亡时以睡眠状态居多。聚集性不明原因猝死病理改变以心肌炎为主,同一家庭内死亡案例间病变可互不相同。散发性不明原因猝死常见的心脏病变依次为心肌脂肪浸润、心肌间质水肿、心肌纤维断裂等非特异性病变和心肌间质局灶性炎性细胞浸润。结论聚集性不明原因猝死符合云南不明原因猝死的特征,其病因可能与季节、环境、遗传等多种因素有关。散发性不明原因猝死大多数具有青壮年猝死综合征的特征。更多还原

【Abstract】 Objective To provide evidence for exploring the cause of death,forensic pathological examination and epidemiological characteristics of the sudden unexplained deaths. Methods The characteristics of 81 sudden unexplained deaths occurred in Yunnan province were retrospectively analyzed,including the age,gender,state before death,the anatomical and histological examination. Results There are 7 cases of aggregative sudden unexplained death and 74 cases of sporadic sudden unexplained death in 81 cases. The aggregative sudden unexplained deaths showed similar characteristics of time,space and family aggregation’s and mostly died in an awake state. Sporadic sudden unexplained death happened more commonly in men during sleep. The myocarditis was most common in the aggregative sudden unexplained death. And in the same family,pathological lesion may differ from each other. The common pathological changes of sporadic sudden unexplained death include myocardial fatty infiltration, interstitial edema and fiber breakage non-specific lesions,and interstitial focal inflammatory cell infiltration. Conclusion Aggregative sudden unexplained death with the features of Yunnan sudden unexplained death may be related with many factors such as season,environment,heredity,and so on. Most of sporadic sudden unexplained death has the characteristics of sudden manhood death syndrome.更多还原
