Cavoportal hemitransposition in liver transplantation: a new technique


   OBJECTIVE: To introduce a new surgical technique--cavoportal hemitransposition in livertransplantation.METHODS: Since Tzakis first reported liver transplantation with cavoportal hemitransposition in thepresence of diffuse portal vein thrombosis in 1998, five relevant research papers have been published, inwhich a total of 23 cases were treated.RESULTS: Of the 23 cases, 11 underwent conventionally cavoportal anastomosis as an end-to-endanastomosis, 8 renoportal anastomosis, and 4 end-to-side anastomosis preceded by piggyback. Eightpatients died after operation. Fifteen patients are still alive with normal liver and kinase function, with alongest follow-up of 37 months.

This new technique is useful and reliable for liver transplantation.……
