Right branch of hepatic portal vein
Ramus dexter venae portae hepatis
- Related terms: Right branch; Hepatic portal vein: Right branch
Definition
The right branch of hepatic portal vein (right hepatic portal vein) bifurcates into two main branches: the anterior segmental branch and the posterior segmental branch. The anterior segmental branch further divides into branches that supply the anterosuperior subsegment (S8) and the anteroinferior subsegment (S5). The posterior segmental branch supplies the posteroinferior subsegment (S6) and the posterosuperior subsegment (S7).
In some cases, anatomical variations can occur. For instance, the anterior segmental branch may bifurcate into anterior and posterior branches towards the respective regions of S8, or it may have a single pedicle. Similarly, the posterior segmental branch can terminate in different forms such as fan-shaped, bifurcated, or tripodal.
