Our technique for auxiliary liver transplantation was based on the technique described by Hess with the exception of the length of the cuff of the graft vena cava and establishment of the portal vein anastomosis.A total of 60 auxiliary liver transplantations were performed,of which 24 were definitive operation.In the 5 definitive operations the grafts survival assessed by 97mTcsodium phytate demonstrated a 1week survival of 100%.How to reduce the complications in auxiliary liver transplantation in rats is discussed in the article.
