Hepatovenous segment VIII at a glance
- What it is
- Couinaud segment VIII is the superior part of the right anterior section of the liver.
- Location
- It lies in the superior anterior right lobe, above the portal bifurcation plane between the middle and right hepatic veins, beneath the diaphragm.
- Function
- 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.
