title: Use of a hydrogel-coated self-expandable coil to salvage a failed transcatheter embolization of a mesenteric hemorrhage.
abstract: HydroCoil (MicroVention, Aliso Viejo, CA, USA) is a self-expanding detachable coil developed to improve the endovascular occlusion of intracranial aneurysms. The hydrogel polymer covering the microcoil expands to several times its original diameter to enhance thrombosis of the intended vessel. We made use of this new technology to occlude a mesenteric artery pseudoaneurysm that failed superselective embolization with standard microcoils.
