An iatrogenic venous air embolism caused by computed tomography (CT) injector occurred in a 74-year-old man undergoing abdominal-pelvic CT for evaluation of an abdominal aortic aneurysm (AAA). During the initial inspection scan of the thoracic part, a large amount of air was detected in the right ventricle, but no contrast medium was noted in the aorta. Surface oxygen was given immediately, and the patient was placed in the left lateral decubitus position on the CT bed. During that time he had no symptoms except coughing. CT revealed no air in the brain or pulmonary vein, and he was returned to his room 55 minutes after the incident. There were no complications during a six-month follow-up period. The importance of daily risk management and immediate proper after care to prevent such accidents was reconfirmed.
一名74岁男性在接受腹部盆腔CT以评估腹主动脉瘤（AAA）时，因计算机断层扫描（CT）注射器导致医源性静脉空气栓塞。在胸部的初始检查扫描期间，右心室内检测到大量空气，但主动脉内未发现造影剂。立即给予面罩吸氧，并将患者置于CT检查床上的左侧卧位。在此期间，他除了咳嗽外没有其他症状。CT显示脑部或肺静脉内没有空气，事件发生55分钟后他被送回病房。在六个月的随访期内没有并发症。再次证实了日常风险管理和立即适当的后续护理对于预防此类事故的重要性。
