Bilateral Congenital Pelvic Arteriovenous Malformation: A Case Report and Review of Literature.

This study aims to demonstrate the effectiveness of a transvenous approach in cases of embolization of pelvic paravesical arteriovenous vascular malformations (AVMs). The key to successful treatment lies in occluding the shunt point within the aneurysmal dominant outflow vein's wall, which can be reached transvenously and potentially through direct percutaneous puncture. Although arterial occlusion can be performed additionally, it should not be performed alone due to its higher risk of AVM persistence/recurrence.
