Some electrocution deaths occur without detectable current marks on the skin, making forensic examination to determine the true cause of death more difficult. Because arterial thrombosis was a frequent finding in victims of electrocution, we investigated injury to the endothelium of the aorta and pulmonary artery with a scanning electron microscope in five cases of death known to be caused by electrocution. We found large pores on the surface of endothelial cells of the aorta and pulmonary artery in those who died of electrocution, but no endothelial membrane perforation was found in those who died of cardiac diseases. These findings were present within 12h after death. Therefore, scanning electron microscopic evidence of endothelial perforation in the aorta and pulmonary artery could be a useful marker to identify electrocution for those victims without detectable current marks on the skin.
一些触电死亡案例中，皮肤上没有可检测到的电流痕迹，这使得法医检查以确定真正的死亡原因变得更加困难。由于动脉血栓形成是触电受害者的常见发现，我们用扫描电子显微镜对5例已知由触电导致死亡的案例进行了主动脉和肺动脉内皮损伤的调查。我们发现，触电死亡者的主动脉和肺动脉内皮细胞表面有大的孔隙，但死于心脏病者未发现内皮膜穿孔。这些发现出现在死亡后12小时内。因此，对于那些皮肤上没有可检测到电流痕迹的受害者，主动脉和肺动脉内皮穿孔的扫描电子显微镜证据可能是识别触电的有用标志。
