Case report. Duplication of the portal vein: a rare congenital anomaly.
Complex developmental changes occur during embryonic life as the vitelline veins evolve into the portal vein. Duplication of the portal vein is an uncommon anomaly. Complications of this anomaly include variceal bleeding, portal hypertension and duodenal obstruction. We report a case of this uncommon anomaly and present an embryological perspective as to the cause for this abnormal configuration of the portal veins.
