What is The right lobe of liver consists of which of the following surgical segments? and explain in detail?
Liver is divided into 8 surgical segments based on poal segmentation, such that any of the 8 segment can be resected while preserving the vascular inflow, venous outflow and biliary drainage of remaining segments. Right lobe of liver consist of segments V, VI,VII and VIII. The right liver is divided into anterior (segment V and VIII) and posterior (segment VI and VII) by right poal scissura comprising of right hepatic vein. Left lobe consists of segment II, III and IV. Left lobe is divided into left lateral section (segments II and III) and left medial section segment IV) by left poal scissura. Segment I or caudate lobe is autonomous as its vasculature and biliary drainage is independent of the poal pedicles and the hepatic veins. Ref: Surgical Oncology edited by David L Balett, page 424.
