Abstract
The Ovation Abdominal Stent Graft System is a trimodular endoprosthesis planned to overcome the limitations of currently available stent grafts, allowing complex iliac and femoral access and providing a proximal seal in challenge infrarenal neck morphology. The proximal sealing is achieved by means of a network of inflatable rings filled with low-viscosity radiopaque polyethylene glycol-based polymer during stent-graft deployment. The leakage of polymer outside the channel to fill the rings into the vascular system may induce an hypersensitivity reaction and anaphylactic shock. We report a case of anaphylactic reaction during Ovation Abdominal Stent Graft System implantation. The endovascular procedure was successfully concluded.
