title: Pelvic arteriovenous malformation treated by superselective transcatheter venous and arterial embolization.
abstract: We describe a rare case of hematuria and hemospermia associated with pelvic arteriovenous malformation (AVM) in a male patient treated by transcatheter embolization. Understanding AVM hemodynamics contributes to the elucidation of its pathology and improves the outcome of embolization. In the present case, multiple arteriolar components shunted to the initial part of a single dominant outflow vein. Superselective embolization of a draining vein and feeding artery with an n-butyl cyanoacrylate/lipiodol mixture and polyvinyl alcohol particles was effective in terms of shunt disappearance and minimizing the need for subsequent arterial embolization.
