Portal Hemodynamics in Liver Resection and Transplantation.

The hepatic blood supply and its several homeostatic and pathologic processes has always been a matter of great interest. Many views commonly held today are derived from an earlier era, but major reorientations have occurred recently in almost all aspects of knowledge of the role and regulation of hepatic blood flow. Moreover, with the advent of liver transplantation (LT), especially living donor LT (LDLT) there has been a resurgence of interest in attempting to comprehend this deceptively simple topic. It is nonetheless important to concede that even though our knowledge on the practical modulation of hepatic hemodynamics has expanded enormously, there still remain the need to explore the depths of our remaining ignorance to further improve outcomes in LDLT. This review focuses on the current view, controversies and gaps in knowledge of the hepatic vascular bed, with an emphasis on the importance of portal hemodynamics in liver disease and its impact on liver regeneration and LT.
