Abstract
Liver diseases especially bilharzial liver diseases, HCV infection and HCC become prevelant in Egypt and cause end stage liver diseases (ESLD). Liver transplantation is one of the solutions for ESLD but with some restrictions.Types of liver transplantation include split liver transplantation, living donor liver transplantation, auxiliary liver transplantation and Xenotransplantation.The donor should be medically and psychologically suitable for living donation. Potential donor candidates undergo a similar medical evaluation as the recipient.Both donor and recipient should undergo strict Post operative care as many complications can result from the procedure e.g. operative bleeding, Primary or delayed nonfunctioning, acute or chronic rejection, biliary leak and infections. Ninety-six percent of donors are able to return to work after 10 weeks of surgery. There are multiple hepatic artery variations which may be in origin, in number or in the course of the artery. According to the origin the hepatic artery may originate from the celiac trunk or its branches, from the superior mesenteric artery or its branches or from both celiac and superior mesenteric artery. According to the number of the hepatic arteries, they may be one hepatic artery, two hepatic arteries and three or more hepatic arteries.Portal vein variations include main PV branching pattern variations, right PV variations and PV origin variations. Biliary tracts variations include both extra and intra hepatic bile duct system. The extra hepatic bile duct system includes cystic duct variations and bile ducts variations (both aberrant and accessory bile ducts). Intra hepatic bile duct system anomalies include right posterior duct and its fusion with the right anterior or left hepatic duct, the right posterior duct pass anteriorly to the right anterior duct and triple confluence. Hepatic veins are arranged in two groups, an upper group (the main hepatic veins) and a lower group (the accessory hepatic veins). The number, size and location of the main hepatic veins are significantly different from those of the accessory hepatic veins. The main hepatic veins are classified according to their location into right, left and middle hepatic veins. The accessory hepatic veins are classified according to their location on the anterior wall of the IVC into superior or inferior right, superior or inferior left and superior or inferior intermediate hepatic veins.
