To study the pathologic findings seen in lethal cases due to accidental electrocution.
The macroscopic and microscopic findings in 16 autopsy cases died of electrocution encountered during the period from January, 2001 to July, 2008 were retrospectively reviewed.
Typical electric marks were found on gross examination in 5 of the 16 cases studied. Histologically, 11 of the 16 cases showed evidence of electric burn. The morphologic features of atypical electric marks varied. Simple epidermal exfoliation and color changes were relatively common. Pathologic changes in internal viscera included disarray of myocardial fibers. Rupture of myocardial fibers was readily identified than in non-electrocution death. Sometimes, focal interstitial hemorrhage and polarization of endothelial cells were seen.
The electric marks on the skin, as confirmed by histologic examination, remain important sequelae of electrocution. The pathologic changes seen in myocardium provide additional clues to the diagnosis.
研究意外触电致死病例的病理表现。
回顾性分析2001年1月至2008年7月期间遇到的16例触电死亡尸检病例的大体和微观表现。
在研究的16例病例中,5例在大体检查时发现典型电痕。组织学上,16例中有11例显示电烧伤证据。非典型电痕的形态特征各异。单纯表皮剥脱和颜色改变较为常见。内脏病理改变包括心肌纤维排列紊乱。与非触电死亡相比,心肌纤维断裂更容易识别。有时可见局灶性间质出血和内皮细胞极化。
经组织学检查证实的皮肤电痕仍然是触电的重要后遗症。心肌中所见的病理改变为诊断提供了额外线索。
