Abstract

The anatomy of middle hepatic vein (MHV) varies widely, and some individuals have aberrant MHV anatomy, thus there is risk of iatrogenic damage to graft MHV during liver splitting. We present the clinical sequences of an adult recipient who received a split right liver graft with erroneous deprivation of the MHV trunk. This is the case was a 58-year-old male patient with hepatitis B virus-associated liver cirrhosis who suffered from hepatic encephalopathy. The split right liver graft had a graft-to-recipient weight ratio of 2.1%. Soon after graft reperfusion, large-sized hepatic venous congestion (HVC) appeared at the graft liver surface, indicating lack of MHV drainage. The amount of HVC was approximately 20% of the right liver graft mass at day 1, which had gradually reduced on follow-up computed tomography (CT) scans. Although liver function recovered progressively, the patient remained bed-ridden because of pre-existing hypoxic brain damage. The patient passed away 4 years after transplantation because of pneumonia and multi-organ failure. The present case implies that there is some possibility of unrecognized damage to the graft MHV during liver splitting, suggesting the necessity of preoperative donor abdomen CT scan and preparation of intraoperative ultrasonography for easy evaluation of graft liver MHV anatomy.
