Introduction: The Left Hepatic Vein (LHV) and the Middle Hepatic Vein (MHV) presents with wide variations, the knowledge of which is very important during various surgeries of the left lobe as well as right lobe of liver.
Aim: To study about the variations in the branching pattern of LHV and the MHV draining the left lobe of liver.
Materials and Methods: A total of 60 adult human livers were dissected manually. The LHV and the MHV were typed into five types. Further, few of these types were again divided into subtypes.
Results: The incidence of presence of common trunk of LHV and MHV was 76.6% (n=46). In 20% (n=12) livers these veins were present as separate trunks. In 3.33% (n=2), no trunk of the LHV was seen and the left medial vein and the left lateral vein were found to drain independently into the Inferior Vena Cava (IVC).
Conclusion: Appropriate knowledge of the anatomy of liver is very important, for different surgical procedures for treatment of malignancies or other ailments of liver.
