The presence of portal venous gas within the hepatic parenchyma is usually associated with a guarded prognosis and a mortality rate approaching 75%. However, there are infrequent causes of portal venous gas not associated with dire clinical outcomes. We describe three patients who made uneventful clinical recoveries after presenting with clinical and imaging manifestations of ischaemic bowel and hepatic portal venous gas, two of which had distended but non-necrotic bowel at laparotomy.
肝实质内门静脉积气通常与预后不良及死亡率接近75%相关。然而，门静脉积气也有一些罕见病因，与严重的临床结局无关。我们描述了三名患者，他们在出现缺血性肠病和肝门静脉积气的临床及影像学表现后临床恢复顺利，其中两名患者在剖腹手术时肠管扩张但未坏死。
