The number of IVC filter-related complications has increased with their growing utilization; however, IVC filter perforation of the duodenum is rare. It can manifest with nonspecific abdominal pain, gastrointestinal bleeding, cava-duodenal fistula, or small bowel obstruction.
Case Report: A 67-year-old female presented with several years of right upper quadrant abdominal pain which was exacerbated by movement and food intake. She had a history of hepatic steatosis, cholecystectomy, and multiple DVTs with inferior vena cava filter placement. Physical exam was unremarkable. Laboratory tests demonstrated elevated alkaline phosphatase and transaminases. Esophagogastroduodenoscopy revealed a thin metallic foreign body embedded in the duodenal wall and protruding into the duodenal lumen with surrounding erythema and edema, but no active hemorrhage. Further evaluation with non-contrast CT scan revealed that one of the prongs of her IVC filter had perforated through the vena cava wall into the adjacent duodenum. Exploratory laparotomy was required for removal of the IVC filter and repair of the vena cava and duodenum. Her post-operative course was uneventful.
Conclusions: In patients with history of IVC filter placement with non-specific abdominal pain, a high clinical suspicion of IVC filter perforation of the duodenum should be raised, as diagnosis may be challenging. CT scan and EGD are valuable in the diagnosis. Excellent outcomes have been reported with open surgical filter removal. Low retrieval rates of IVC filters have led to increased complications; hence, early removal should be undertaken as clinically indicated.
