Hepatovenous segment VI at a glance
- What it is
- Couinaud segment VI is the inferior part of the right posterior section of the liver.
- Location
- It lies in the inferior right lobe, lateral and posterior to the right hepatic vein, below the transverse plane through the portal bifurcation.
- 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.
- Body system
- Digestive · single, midline structure
- FMA ID
- FMA15744 (Foundational Model of Anatomy)
Key facts
- It lies in contact with the right kidney and the hepatic flexure of the colon.
- Segments VI and VII form the right posterior section, supplied by the right posterior portal branch and drained mainly by the right hepatic vein.
