Duodenal-caval fistula from eroding inferior vena cava stent requiring explant and duodenal repair.

A 36-year-old male, with a prior history of an abdominal gunshot wound requiring duodenojejunostomy and inferior vena cava (IVC) repair, complicated by subsequent IVC occlusion requiring stent placement, presented 13 years after his initial injuries with abdominal pain and septic shock secondary to erosion of the IVC stent into the duodenum, forming a duodenal-caval fistula, resulting in bacteremia and fungemia. He underwent successful partial IVC stent explant and duodenal repair. Although rare, the possibility of IVC stent erosion into adjacent structures should be considered as a potential complication following IVC stent reconstruction in reoperative fields.
