摘　　要：目的运用尸体CT(PMCT)观察心包内积血的形态学改变。方法对我单位2019年1月~2020年6月发现心包积血的8例尸体CT图像进行回顾性分析,结合案情、鉴定书中记录的心包腔出血量和最终死亡原因,分析心包填塞死亡的典型死后CT表现。结果8例有心包积血的案例中,有5例心包积血呈"双环征",法医认定心包填塞为死因,有1例心包积血呈"单环征",法医认定死亡原因为急性失血性休克,有2例心包积血呈分层状,法医认定死亡原因为颅脑损伤1例,机械性窒息合并脊髓横断1例。结论PMCT能帮助法医将观察到的心包积血的形态进行分型,进而确定是否可以将心包填塞作为死亡原因。Objective To observe the morphological changes of hemopericardium by autopsy CT(PMCT). Methods PMCT images of 8 cases with hemopericardium in our unit from January 2019 to June 2020 were retrospectively analyzed. The typical PMCT findings of pericardial tamponade as cause of death were analyzed based on the case details, quantity of hemopericardium. Results Among the 8 cases with hemopericardium, 5 cases showed typical or atypical "double-ring stratification", the cause of death was pericardial tamponade, 1 case showed "single-ring stratification", the cause of death was 1 hemorrhagic shock, 2 cases showed stratified, the cause of death was head trauma, and mechanical asphyxia with spinal transection. Conclusion PMCT can help to determine whether pericardial tamponade can be used as the cause of death by morphology of the hemopericardium.
