Hepatovenous segment VII: anatomy, location and function

Couinaud segment VII is the superior part of the right posterior section of the liver. Each Couinaud segment is a functionally independent unit of liver with its own portal triad (portal vein branch, hepatic artery branch, bile duct) and hepatic venous drainage, so it can be resected separately.
