In seven (18%) of 39 liver transplantation patients, serial Doppler sonographic examinations performed in the first 2 weeks after the transplantation showed transient, highly echogenic nonshadowing particles moving within the portal vein, believed to be portal venous air. This finding was associated with sepsis in one patient, a positive stool culture for Clostridium difficile in another, and postoperative ileus in a third patient. A fourth patient had primary graft failure and required a second transplant. No potential cause was found in the other three patients. None of the patients had bowel infarction or necrosis. The finding was not associated with transplant rejection or graft infection. We conclude that the sonographic finding of portal venous gas is common in the first 2 weeks after hepatic transplantation and may not have grave prognostic significance.
在39例肝移植患者中，有7例（18%）在移植后的前2周内进行的系列多普勒超声检查显示，门静脉内有短暂的、高回声不伴声影的颗粒移动，被认为是门静脉积气。这一发现与1例患者的脓毒症、另1例患者艰难梭菌粪便培养阳性以及第3例患者的术后肠梗阻有关。第4例患者发生原发性移植肝无功能，需要再次移植。其他3例患者未发现潜在病因。所有患者均无肠梗死或坏死。该发现与移植排斥或移植物感染无关。我们得出结论，门静脉积气的超声表现在肝移植后的前2周很常见，可能没有严重的预后意义。
