A portal vein aneurysm is the dilatation of the portal vein due to a defect in the vein wall. This rare disease manifestation is difficult to predict and has the potential for severe complications. We describe the case of a 68-year-old man involved in a motor vehicle collision who presented with abdominal hemorrhage found on ultrasound, hypotension, and vague abdominal pain. The patient underwent an exploratory laparotomy to control bleeding. Surgery and a subsequent abdominal computed tomography revealed the presence of a portal vein pseudoaneurysm and shock bowel. This case highlights the importance of radiologists to consider the prospect of portal vein aneurysm in the differential diagnosis of hypotension following abdominal trauma.
门静脉瘤是由于静脉壁缺陷导致的门静脉扩张。这种罕见的疾病表现难以预测，且有发生严重并发症的可能。我们描述了一例68岁男性的病例，该患者在机动车碰撞事故后，超声检查发现腹腔内出血、低血压和腹部隐痛。患者接受了剖腹探查术以控制出血。手术及随后的腹部计算机断层扫描显示存在门静脉假性动脉瘤和休克肠。该病例强调了放射科医生在腹部创伤后低血压的鉴别诊断中考虑门静脉瘤可能性的重要性。
