  • Title: Incidental Preduodenal Portal Vein Causing Partial Duodenal Obstruction and Hypertrophied Pre-Pyloric Gastric Polyp.
    Author: Briscoe WE, Urevick A, Fisher J, Bhattacharya SD.
    Journal: Am Surg; 2023 Aug; 89(8):3673-3674. PubMed ID: 37139836.
    Abstract:
    Preduodenal portal vein (PDPV) is a rare congenital anomaly in which the portal vein lies anterior to the duodenum rather than its normal posterior position. It is a known rare cause of duodenal obstruction and can be associated with other anomalies such as malrotation with or without jejunal atresia. Presented is an incidentally found PDPV causing partial duodenal obstruction during exploration for the resection of a gastric mass and placement of open gastrostomy tube for feeding. This was managed with duodenoduodenostomy, re-creating normal anatomy with portal.
