Cadaveric study of portal and hepatic venous anatomy with special reference to territory of middle hepatic vein

Background: Liver transplantation has become the standard therapy for end-stage chronic liver disease and acute hepatic failure. The shortage of cadaveric donor organs deceased donor liver transplant (DDLT) has led to the development of living donor liver transplantation (LDLT). In LDLT the concept is based on the potential regenerative power of the human liver.Methods: This was an observational study done in department of surgery, Gandhi Medical College and Hamidia Hospital, Bhopal on 50 cadaveric liver specimens and dissection was carried out in department of Anatomy from March 2018 to February 2019.Results: In this study 50% of the specimens had all the three hepatic veins, while the remaining 50% had two hepatic veins: the right and left. The presence of one or more right accessory hepatic veins draining the right lobe was observed in all the cases. In most of the livers the LHV and MHV formed a common trunk, which joined the IVC (76.0%). In some cases, they drained independently into IVC (18%). In the present study of 38 adult cadaveric livers, termination of PV was observed as extra hepatic in 89.47 livers, Intrahepatic in 2.63% and at the capsule in 7.89% livers.Conclusions: There are three main hepatic veins: RHV, MHV and LHV. In this study 50% of the specimens had all the three hepatic veins, while the remaining 50% had two hepatic veins: the right and left. Thus significant variation was seen and it could definitely be helpful to hepatobilliary surgery and in liver transplant.
