To describe radiological appearances of systemic air emboli versus intravascular air from putrefaction.
The hospital trauma database was searched for patients who underwent computed tomography (CT) autopsy. The studies were reviewed and evaluated for intravascular gas. The appearances and location of intravascular air were characterised.
Four cases of intravascular gas were identified out of 15 cases of CT autopsy performed from March 2004 to December 2006. In three cases, intravascular air was predominantly in the arterial system, coupled with severe pulmonary injury. In one case, the air was predominantly in the venous system with a large amount of gas in portal veins.
We propose to consider pulmonary alveoli-venous fistula as a possible cause of systemic air emboli, as identified on CT autopsy by large amounts of gas in the arterial circulation, coupled with severe pulmonary injury.
描述全身空气栓塞与腐败性血管内气的放射学表现。
在医院创伤数据库中搜索接受计算机断层扫描（CT）尸检的患者。对研究进行了回顾和评估，以确定血管内气体。描述和定位血管内空气。
2004 年 3 月至 2006 年 12 月期间，对 15 例 CT 尸检进行了研究，共发现 4 例血管内气体。在 3 例中，血管内空气主要存在于动脉系统，伴有严重的肺部损伤。在 1 例中，空气主要存在于静脉系统，门静脉内有大量气体。
我们建议将肺泡-静脉瘘作为全身空气栓塞的一个可能原因，通过 CT 尸检可以发现大量气体在动脉循环中，伴有严重的肺部损伤。
