title: Should all hepatic arterial branches be reconstructed in living-related liver transplantation?
abstract: BACKGROUND
  Because graft arteries are smaller and shorter in living-related liver transplantation (LRLT) than in whole or reduced-size liver transplantation from cadavers, arterial reconstruction is thought to be one of the critical points for success.
  
  
  METHODS
  Thirty LRLT patients were classified into two groups: those in whom all graft hepatic arteries were reconstructed (group A), and those whom only had some were reconstructed (group B). In group A 17 patients had a single hepatic artery and three had two hepatic arteries. In group B the thickest one of several arteries was reconstructed, but the others were ligated after pulsatile back-bleeding from their cut stumps had been confirmed. The clinical results were compared between the two groups.
  
  
  RESULTS
  Neither arterial thrombosis nor liver dysfunction related to the arterial blood supply was observed during the postoperative course. One case of bile leakage and two cases of bile duct stenosis occurred in group A. No significant difference was noted in the postoperative values of aspartate aminotransferase, alanine aminotransferase, and lactate dehydrogenase between the two groups. Overall patient and graft survival was 90%.
  
  
  CONCLUSIONS
  Although several hepatic arteries may supply the potential allograft in LRLT, it is not always necessary to reconstruct all of them.
