ABSTRACT
Portacaval shunt with interposition of 6 mm H-graft of PTFE is a real partial shunt. In this experimental study, the operation has been well tolerated and has been compared with 8 mm H-graft and direct "vein to vein" portacaval shunt. Intraoperative data show that 6 mm is the ideal diameter for a portacaval shunt to prompt an experimental model based on partial decompression of portal bed in animals in this size.

A facilitated technique of porcine donor hepatectomy is reported underlying the possibility to make an easy procedure without in situ portal perfusion, so other abdominal organs supplied by superior mesenteric system can be harvested at the same time. The viability of those grafts procured without in situ portal perfusion has been compared with an other group of livers harvested with in situ aortic and portal flushing. The evaluation of the histology and early graft function two hours after riperfusion has shown no differences between both groups.
