Abstract Background: An intimate knowledge and awareness of branching patterns of main portal vein is necessary before hepatic surgeries. The presence of portal vein variants increases the risk of bile duct hilar anatomical variations also. This information may be of help for accurate radiological interpretation, to prevent complications like hemorrhage, difficult anastomosis in the recipient, ischemia in the graft and allograft failure at the time of liver transplantation. Hence the present study was conducted with the objective of observing the branching pattern of the main portal vein, to measure length of right portal vein and angle between right and left portal vein. Material and Methods: The present study was conducted on 84 liver specimens of human cadavers fixed with 5% formalin, collected from the Department of Anatomy and Forensic Medicine, MMC&RI, Mysore. The parameters were measured using image J software. Results: Bifurcation of main portal vein was seen in 75 liver specimens [89.3%]. Trifurcation of main portal vein was seen in 9 specimens [ 10.7%]. Mean angle between Right and left portal vein was 146.7°. Mean length of right portal vein was 2.27 cm. Conclusion: Knowledge of portal vein variations is critically significant in surgical resection and transplantation procedures. Resection of any portion of liver should be well planned and clear identification of sub segments of liver is necessary before surgery. Surgeons and radiologists must have a thorough understanding of variants in portal vein anatomy in order to prevent injury to portal vein and for successful radiological interventions.

Although many fine structural studies on the vertebrate liver have been reported on mammals, avians, reptiles, amphibians, teleosts and cyclostomes, there are no studies on elasmobranchii liver except one by T. Ito etal. (1962) who studied it on light microscopic level. The purpose of the present study was to as certain the ultrastructural details and cytochemical characteristics of normal elasmobranchii liver and was to compare with the other higher vertebrate ones.Seventeen Scyliorhinus torazame, one kind of elasmobranchii, were obtained from the fish stock of the Ueno Zoo aquarium, Ueno, Tokyo. The sharks weighing about 300-600g were anesthetized with MS-222 (Sigma), and the livers were fixed by perfusion fixation via the portal vein according to the procedure of Y. Saito et al. (1980) for 10 min. Then the liver tissues were immersed in the same fixative for 2 hours and postfixed with 1% OsO4-solution in 0.1 Mc acodylate buffer for one hour. In order to make sure a phagocytic activity of Kupffer cells, latex particles (0.8 μm in diameter, 0.05mg/100 g b.w.) were injected through the portal vein for one min before fixation. For preservation of lipid droplets in the cytoplasm, a series of these procedure were performed under ice cold temperature until the end of dehydration.
