EXTRA-HEPATIC PART OF PORTAL VEIN – A CADAVERIC STUDY IN ADULTS & FOETUSES

Abstract

Background: Variations of the Hepatic Portal Vein are encountered during abdominal surgeries. Aim: The present study is an observational study of the extrahepatic part of Portal Vein & its variations on cadavers. Materials & Methods: A total of 50 upper abdomen dissections were carried out to delineate extra-hepatic Portal Vein anatomy. The Results: mean length of Portal Vein was 5.96cm. The mean diameter of Portal Vein was 1.35cm. The most common type of formation of Portal Vein was Type I, found in 64%. The Right Gastric Vein commonly emptied into the trunk of the Portal Vein. The Left Gastric Vein commonly emptied into the trunk of the Portal Vein in 87.18%. The most common type of Portal Vein termination was Extra-Hepatic, found in 76% of 50 dissections. The Bifurcation pattern was the most common pattern of Portal Vein termination, found in 94% of dissections. The ndings of the present Conclusion: study highlight the variations that may occur in the hepatic portal venous system in its extra-hepatic part. Sound knowledge of portal venous anatomy is needed for success in the surgeries of the liver & adjacent viscera.
