Liver abscess developed after cadaveric liver transplantation due to ligation of an accessory right hepatic artery of the donor graft

초록

It is important that extrahepatic arteries are identified precisely at the time of graft procurement. We present a case where the accessory right hepatic artery of the liver was ligated leading to postoperative liver abscess formation in the liver graft. A forty-seven-year-old female patient diagnosed with liver cirrhosis underwent orthotopic cadaveric liver transplantation due to altered mentality. The donor graft showed a variant of the hepatic artery anatomy where an accessory right hepatic artery arose from the superior mesenteric artery. This artery was accidentally transected during procurement. Since the back bleeding test using perfusion fluid was good, the artery was ligated. Postoperative abdominal computed tomography scan revealed a 6 cm low attenuating lesion in the liver. The patient underwent conservative treatment. We believe that even small accessory arteries (1 to 2 mm) should be reconstructed whenever possible to avoid postoperative complications such as liver abscess.
