Hepatic portal venous gas is a radiological finding due to the presence of gas in the portal vein. It was associated with a mortality rate ranging from 75% to 90% and with an indication for exploratory laparotomy. We report one case following an abdominal trauma. The portal vein gas was detected on CT Scan. The patient who was asymptomatic was not operated on and survived. The severity of this radiological symptom requiring a laparotomy has to be reassessed. CT Scan is the most efficient method to recognize portal vein gas and its larger use has allowed to diagnose more cases not detected by simple abdominal X-rays. In conclusion, surgical exploration should not be done systematically but has to be decided in relation with the clinical status of the patient.
肝门静脉积气是一种因门静脉内存在气体而产生的影像学表现。其死亡率在75%至90%之间，并提示需进行剖腹探查术。我们报告1例腹部创伤后的病例。CT扫描检测到门静脉积气。该患者无症状，未接受手术，存活下来。对于这种需要剖腹手术的放射学症状的严重程度必须重新评估。CT扫描是识别门静脉积气最有效的方法，其更广泛的应用使更多通过简单腹部X线检查未发现的病例得以诊断。总之，不应一概而论地进行手术探查，而必须根据患者的临床状况来决定。
