Sepsis with gas-forming organisms, e.g. Clostridium perfringens and anaerobic streptococci occurred in three of 120 liver-transplant recipients (2.5%). The diagnosis was made in all three patients by bedside ultrasound, before blood cultures revealed bacterial growth. Floating high amplitude echoes within the extra- and intrahepatic portal veins and persistent small high amplitude echoes in the non-dependent portion of the liver are indicative of portal venous gas and should prompt further laboratory investigations.
产气性微生物引起的脓毒症，如产气荚膜梭菌和厌氧链球菌，在120例肝移植受者中有3例发生（2.5%）。所有3例患者均在床旁超声检查时确诊，此时血培养尚未显示细菌生长。肝内外门静脉内的高振幅漂浮回声以及肝脏非下垂部位持续存在的小高振幅回声提示门静脉积气，应促使进行进一步的实验室检查。
