A 54-year-old woman was found deceased with incised wounds of both sides of her neck and both wrists. Postmortem CT scanning revealed air in the heart and in the dural veins in continuity with air in the right jugular vein. Death was due to incised wounds of the wrist and neck with blood loss and air embolism. The manner of death was suicide. At autopsy, perfusion of the thoracic ascending aorta produced a fine stream of water emanating from an incised wound of the right ulnar artery with no significant leakage of water from the wound of the left wrist. There was also leakage from the facial artery branch of the right external carotid artery. Perfusion testing can be used as a screening test prior to formal dissection and also to identify small vessels that may not be obvious on standard examination of an exsanguinated field.
一名54岁女性被发现死亡，其颈部两侧和双腕均有切割伤。尸检CT扫描显示心脏内和硬脑膜静脉中有空气，且与右颈静脉内的空气相连通。死亡原因是手腕和颈部切割伤导致失血和气栓。死亡方式为自杀。尸检时，对升主动脉进行灌注，可见右尺动脉切割伤处有细水流渗出，左手腕伤口无明显漏水。右颈外动脉的面动脉分支也有渗漏。灌注测试可在正式解剖前用作筛查测试，也可用于识别在失血区域的标准检查中可能不明显的小血管。
