Abstract

IN REVIEWING the literature on the anatomy of the extrahepatic portal system in the light of present day surgical procedures for the relief of portal hypertension, we were able to find little information on the length and caliber of the major vessels making up the extrahepatic portal systems.1 In the performance of anastomoses between the portal system and the systemic circulation, it is important that the vessels used should have sufficient caliber to be able to transport enough blood in a given time to relieve the hypertension in the portal system.
