Abstract

• The morphologic anatomy of the liver, based on superficial landmarks, has been replaced by functional anatomy, which is more appropriate for liver surgery.

• The liver is divided according to portal pedicles and hepatic veins. Cantlie’s line(where the middle hepatic vein is located) divides the liver in right and left hemilivers.

• The right hemiliver is divided in anterior (segments 5 and 8) and posterior (segments 6 and 7) sectors by a plan where the right hepatic vein is located.

• The left hemiliver is divided in medial (segment 4) and lateral (segments 2 and 3)sectors.

• Segment 1 corresponds to the caudate lobe, located around the vena cava.

• Vascular and biliary variations are very frequent and they have significant implications on liver resections and/or transplantation.
