[Case of giant renal arteriovenous fistula in a long-term hemodialysis patient].

We report a case of giant left renal arteriovenous fistula (AVF). A 36-year-old man was diagnosed with chronic glomerulonephritis (CGN) by biopsy on the left kidney 11 years ago. He had been receiving hemodialysis for end-stage kidney disease from CGN since 10 years ago. A left renal cystic lesion was found and he was referred to our department for examination and treatment. He was diagnosed as having left AVF using imaging techniques (computed tomography, magnetic resonance imaging and Color Doppler ultra sonography). He underwent embolization of left renal artery using microcoils. After the surgery, there were no major complications, and there were no signs reccurence. AVF in a long-term dialysis patient is rare. We report this case and summarize the cases reported in Japan.
