title: Recurrent Admissions for Respiratory Distress Caused by Large Renal AVF.
abstract: Renal arteriovenous fistulas (AVFs) are an uncommon complication of nephrectomy. In this report, we present the case of a 66-year-old female presenting with progressive dyspnea on exertion and exercise intolerance. She was diagnosed and treated for adult onset reactive airway disease. The patient underwent nephrectomy at age 18 secondary to recurrent pyelonephritis from vesicoureteral reflux. She underwent a surveillance computed tomography (CT) scan to evaluate a small ascending aneurysm that was initially detected on cardiac echocardiogram. A large left renal AVF was detected incidentally on the CT scan. The fistula was successfully treated by ligation of the renal artery with resolution of pulmonary symptoms.
