STATING BACKGROUND: Pre-duodenal portal vein (PPV) is a rare congenital anomaly, usually asymptomatic and thus detected only incidentally in adults. It is often associated with other anomalies which can be included into polysplenic syndrome.
Methods:
In this case, a 56-year-old-female was admitted for a degenerative ampullome. The preoperative work-up shows a PPV vein, the absence of inferior vena cava retro-hepatic and the presence of an anastomosis between the inferior vena cava and the azygos system and a complete common mesentery.
Discussion:
Such a discovery is often incidental and of little import; however, it takes on major importance for surgeons because the accidental damage of PPV can lead to serious consequences.
Conclusion:
The aim of this study, based on the embryology of the portal vein focused on a rare anomaly to keep it in mind because this anomaly in case of digestive surgery may need to adjust surgical techniques.
