Anatomy (Structure) of liver

Dr. Vishal Kumar Chorasiya

As mentioned in section of liver and its unique properties and their implications liver is divided into two lobes: Right and left. These lobes are further divided into eight independent segments of which segment 1-4 forms the left lobe while segments 5-8 forms the right lobe. Even the left lobe is further divided into a left lateral segment (which is formed by segment 2 and 3). Similarly, the right lobe is further divided into two sectors; right posterior sector (segment 6 and 7) and right anterior sector (segment 5 and 8). This distribution forms the basis of liver retrieval during living donor liver transplant. Liver can be divided along these planes into functional units which can be retrieved and implanted into another individual without effecting the functions on either side. The choice of selection of the part to be used depends on the individual patient’s requirement, volume distribution and liver vascular and biliary anatomy in donors and complexity of surgical retrieval.
