A 67-year-old dialysis-dependent man presented to the cardiology service with worsening high output cardiac failure and was found to have a harsh, right-sided abdominal bruit on examination. Of significance, he had undergone several laparotomies related to a stab wound experienced 7 years earlier. A computed tomography scan revealed right renal artery pseudoaneurysms with fistulous communication to the vena cava. Successful percutaneous coil embolization and cyanoacrylate gluing enabled fistula closure without renal infarction. Symptoms of cardiac failure ultimately resolved following treatment. Catheter-based therapies provide minimally invasive and effective strategies for treating complicated fistulas involving the renal vasculature.
