Abstract
Aortocaval fistulas following endovascular repair of ruptured abdominal aortic aneurysms (rAAA) are rare. We herein describe repair using an Amplatzer Septal Occluder in a 68-year-old male who presented to the emergency department 6 months after ruptured endovascular aneurysm repair (rEVAR) with right heart failure. With the assistance of diagnostic angiography and intravascular ultrasound, the patient was found to have a 1.2cm diameter aortocaval fistula and a type-II endoleak. His aortocaval fistula was successfully closed using an Amplatzer septal occluder device after failure of attempted closure with an Amplatzer plug and coiling of the aneurysm sac. His symptoms of heart failure improved, and he was discharged to an acute rehabilitation unit. Follow-up at 3 months demonstrated continued improvement in heart failure symptoms, and a small persistent type II endoleak. Aortocaval fistulae are a potentially fatal complication of rAAA. We discuss the sequelae and treatment strategies of aortocaval fistulas following rEVAR including the use of the Amplatzer Septal Occluder.
