Management of Complex Traumatic Renal Artery–Inferior Vena Cava Fistula: A Case Report and Review of the Literature
Background: Renal artery–inferior vena cava (IVC) fistula is usually caused by penetrating injury to the back. However, it is a very rarely reported entity with only 20 cases reported in the literature. They may present acutely with hemodynamic instability or chronically as congestive heart failure. A thorough examination and adequate imaging are required to avoid missing such injuries. Case Presentation: A 28-year-old gentleman presented after sustaining stab injury to the back. The stab had penetrated the renal artery and IVC, leading to arteriovenous fistula. He was managed surgically, as he went into hemorrhagic shock, with a successful outcome. The case is also unique as an accessory renal artery was also involved in the fistula. Conclusion: Early identification and management of renal artery–IVC fistula is important to ensure a successful outcome. Such fistulas can be managed by either endovascular approach or surgical approach. The decision of approach depends on the level of expertise available and hemodynamic status of the patient.
