title: Pre-duodenal portal vein in polysplenia syndrome: clinical effects and surgical application.
abstract: 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.
  
  
  CONCLUSIONS
  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.
  
  
  CONCLUSIONS
  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.
