Abstract

Purpose: Most traumatic deaths in Japan are due to nonpenetrating injuries, especially those that result from traffic accidents; however, the autopsy rate of traffic accident-related deaths is only about 5%. We investigated the diagnostic ability of postmortem computed tomography (PMCT) in cases of fatal trauma after traffic accidents.

Materials and methods: Our subjects were 78 subjects (59 males, 19 females; mean age 50 years, range 15-87 years) who were brought to our institution in cardiopulmonary arrest on arrival after traffic accidents and died despite resuscitation attempts. PMCT findings of damage to the head, neck, thorax, abdomen, and pelvis were classified into three grades according to the Abbreviated Injury Scale (AIS) severity: A: 1 (minor), 2 (moderate); B: 3 (serious), 4 (severe), 5 (critical); C: 6 (maximum).

Results: The percentage ratio of A/B/C in 78 head injuries was 32/60/8, in 41 neck injuries 83/5/12, in 76 thorax injuries 5/38/57, in 76 abdominal injuries 70/24/7, and in 76 pelvic injuries 79/21/0, respectively.

Conclusion: PMCT can detect or presume fatal trauma when diagnosing the cause of death after traffic accidents.

死后计算机断层扫描结果作为交通事故相关致命伤害的证据。
目的:在日本,大多数创伤性死亡是由于非穿透性伤害,特别是由交通事故造成的伤害;然而,交通事故相关死亡的尸检率仅为5%左右。我们探讨了死后计算机断层扫描(PMCT)在交通事故后致命创伤病例中的诊断能力。材料与方法:我们的研究对象为78名,其中男性59名,女性19名;平均年龄50岁,年龄范围15-87岁),因交通事故到达我院时心肺骤停,经抢救无效死亡。头部、颈部、胸部、腹部和骨盆损伤的PMCT结果根据简易损伤量表(AIS)严重程度分为三个等级:A: 1(轻微),2(中度);B: 3(严重),4(严重),5(危急);C: 6(最大值)。结果:78例头部损伤的A/B/C百分比分别为32/60/8、41例颈部损伤为83/5/12、76例胸部损伤为5/38/57、76例腹部损伤为70/24/7、76例盆腔损伤为79/21/0。结论:PMCT在诊断交通事故死亡原因时可发现或推定致死性创伤。
