Abstract
The Ovation Alto stent graft is a unique endovascular abdominal aortic aneurysm repair device. A low-viscosity, radiopaque liquid polymer fills the rings located within the legs of the device. We reported a rare case of a patient diagnosed with an abdominal aortic aneurysm who was surgically treated using endovascular abdominal aortic aneurysm repair with an Ovation Alto stent graft. Polymer underfilling due to contralateral leg twisting of the stent graft’s main body resulted in limb occlusion. We highlighted the importance of avoiding the rotation of the Ovation Alto stent graft, thus preventing the potential twisting of this device within the sheath after the insertion of the stent graft’s main body.
期刊介绍：
Journal of Vascular Surgery Cases and Innovative Techniques is a surgical journal dedicated to publishing peer review high quality case reports, vascular images and innovative techniques related to all aspects of arterial, venous, and lymphatic diseases and disorders, including vascular trauma, malformations, wound care and the placement and maintenance of arterio-venous dialysis accesses with an emphasis on the practicing clinician. The Journal seeks to provide novel and timely information to vascular surgeons, interventionalists, phlebologists, wound care specialists, and allied health professionals involved with the management of patients with the entire spectrum of vascular disorders.
