血液透析患者并发肝门静脉积气1例

One Case of Hepatic Portal Venous Gas in a Hemodialysis Patient

摘要: 肝门静脉积气(Hepatic portal venous gas, HPVG)是门静脉系统内出现气体的罕见影像学表现。这种情况在临床实践中相对少见。其早期死亡率极高，超过75%，并且曾被视为预后不良的标志。随着影像学技术的进步，尤其是CT的普及，HPVG的检出率有所提升，但其病死率仍居高不下。治疗需根据病因及患者全身状况选择手术或保守方案。本文介绍一例血液透析期间突发腹痛、经影像证实为HPVG并接受非手术治疗的病例，通过分析其诊治经过，为临床识别和处理此类情况提供参考。

Abstract: Hepatic portal venous gas (HPVG) refers to the imaging manifestation of abnormal gas accumulation in the portal vein and its branches, which is relatively rare in clinical practice. The early mortality rate is extremely high, reaching over 75%, and was once regarded as a sign of poor prognosis. With the advancement of imaging techniques, especially the popularization of CT, the detection rate of HPVG has increased, but its mortality rate remains high. The treatment should be based on the cause of the disease and the overall condition of the patient to choose surgical or conservative options. This article presents a case of sudden abdominal pain during hemodialysis, which was confirmed as HPVG by imaging and received non-surgical treatment. By analyzing the diagnosis and treatment process, it provides a reference for clinical identification and management of such situations.
