Cystoscopic management of an extruded coil from arteriovenous fistula embolization using arthroscopic instruments.

Pelvic arteriovenous malformation (AVM) is a rare condition in which a section of blood vessels lacks a capillary network, resulting in blood from an artery being delivered directly to a vein. This condition may be congenital or acquired. Percutaneous selective embolization can obliterate AVMs and has increasingly been used for management. Management involves transcatheter embolization with either inert glues, balloons, or fibered titanium coils that are designed to limit the flow through feeding vessels. We describe one potential complication of transcatheter embolization that involves necrosis of the bladder wall with a novel technique for endoscopic management of an extruded coil in the bladder.
