[Congenital pelvic arteriovenous fistula in a male. A case report]

A congenital arteriovenous fistula (AV fistula) in the true pelvis is extremely rare, especially in males. We present a case of this disease with pollakiuria and intrarectal discomfort. Diagnosis was made by computed tomography and magnetic resonance imaging and confirmed by cine angiography. Because the AV fistula involved the bladder, prostate and rectum, ligation of the main feeding arteries was performed. He also had benign prostatic hypertrophy and was treated by conservative therapy because of a high risk of massive bleeding in surgical treatment.
