Two cases of portal venous gas (PVG) are presented. One case due to bowel infarction and another due to duodenal ulcer perforation complicated by a subphrenic abscess. The diagnosis was suggested from plain abdominal radiographs and confirmed by unenhanced computed tomography (CT) of the abdomen which is superior to demonstrate gas in the portal venous system. The distinction between PVG and biliary gas is briefly discussed.
本文报告了两例门静脉积气（PVG）病例。一例是由于肠梗死，另一例是由于十二指肠溃疡穿孔并发膈下脓肿。腹部平片提示了诊断，并通过腹部非增强计算机断层扫描（CT）得以证实，CT在显示门静脉系统积气方面更具优势。本文还简要讨论了PVG与胆系积气的鉴别。
