RENAL ARTERIOVENOUS FISTULA (ANEURYSMAL TYPE) TREATED BY NEPHRECTOMY UNDER BALLOON CATHETER OCCLUSION OF RENAL ARTERY: A CASE REPORT

: A 60-year-old man presented with leg edema and shortness of breath. He was being treated with medication for chronic heart failure for the past 3 years and had been in a traffic accident when he was 13 years old. Computed tomography showed a huge right renal arteriovenous fistula (AVF). The right renal artery measured 16 mm in diameter, the renal aneurysm was observed to be 60 mm, renal vein 87 mm, and the inferior vena cava 60 mm in diameter. His high-output heart failure was attributed to his right renal AVF, for which treatment was deemed necessary. Due to the risk of pulmonary embolism associated with transcatheter arterial embolization, we performed a nephrectomy with temporary interruption of renal blood flow using a balloon catheter. He was observed to be asymptomatic immediately after surgery.
