Right portal fissure
Fissura portalis dextra
Definition
The right portal fissure is the vertical plane that divides the right part of the liver into the right medial and right lateral divisions for the hepatic segmentation.There is no anatomical marking on the surface of the liver but corresponds as a projection of the right hepatic vein.
The right portal fissure is traced by drawing an imaginary line that starts at the lowest part of the lower margin of the liver and from there goes upwards and backwards until it reaches the right margin of the inferior vena cava.
