Computed Tomography Angiography Demonstration of Portal Vein Anomaly Type V

Abstract

Computed tomography (CT) angiography is fast replacing the diagnostic conventional angiography and digital subtraction angiography. A case of a type V portal vein anomaly, which was diagnosed by Doppler ultrasound and confirmed on CT angiography, is presented. Demonstration of the portal vein branching pattern and its anomalies assumed importance and significance after split liver and segmental transplantation techniques were developed. There are 5 variations of portal vein branching that have been described.
