Absent portal vein bifurcation

Case contributed by Igor Yarmola
Diagnosis certain

Presentation

Absence of left portal vein at ultrasound screening

Patient Data

Age: 4 months
Gender: Female

Absent portal vein bifurcation and single intrahepatic portal venous (IHPV) arch running from right to left lobe of the liver.

Case Discussion

Absence of bifurcation of the portal vein is an extremely rare anomaly. Portal vein branching anomalies occur due to aberration of normal anastomotic patterns and involution of vitelline veins during the development of portal vein. There is no clinical significance.

This case is presented together with my colleagues Reshetarov I. and Barskiy V.
