The right portal vein divides into which two branches?

The right portal vein divides into which two branches?

• A. Anterior and Posterior
• B. Superior and Inferior
• C. Lateral and Medial
• D. Anterior and Lateral

Answer: (A)

In hepatic vascular anatomy, the portal vein divides into right and left branches, and the right portal vein further splits into two branches: anterior and posterior. The anterior branch supplies the front part of the right lobe (segments V and VIII), while the posterior branch supplies the back part (segments VI and VII). This pattern is distinct from the left portal vein, which divides into medial and lateral branches. Recognizing the anterior and posterior division of the right portal vein helps localize disease and plan targeted imaging or interventions in ultrasound.
