- Abstract
A modified technique to perform the successive perfusions of the liver that are necessary for its preservation by the simple perfusion method and hypothermic storage is presented. This technical variety has been tested on Large White pig's livers and consists in doing the successive perfusions of cooling, preservation and washout, first through the hepatic artery and there after through the portal vein. The macroscopic and biochemical characteristics of the effluents obtained through the infrahepatic inferior vena cava during the perfusion-washout of the livers at the end of the period cold ischemia shows its effectiveness. Likewise, the hepatic perfusion-washout begun via the arterial vein and finished via the portal one avoids post-revascularization hyperpotassemia in the receptor animals. It is hypothesized that the arterial protoganism of perfusions, when the simple perfusion and hypothermic storage method of hepatic preservation is used, could be a prophylaxis against complications of a post-transplant biliary origin.
