  • Title: Iliac Stent Migration during Thoracic Endovascular Aortic Aneurysm Repair Resulting in Functional Coarctation.
    Author: Clementi J, Lim S, Halandras P, Aulivola B, Crisostomo PR.
    Journal: Ann Vasc Surg; 2017 Nov; 45():269.e1-269.e4. PubMed ID: 28739470.
    Abstract:
    Iliac arterial disease, unfavorable anatomy, and prior stenting all pose challenges to access in endovascular abdominal aortic repair (EVAR) and thoracic aortic repair (TEVAR). Iliac access injury during T/EVAR may lead to rupture, dissection, thrombosis, or distal ischemia. Some have advocated iliac stent prior to T/EVAR in patients with suboptimal iliac access. The rate of complication and iliac stent migration during subsequent T/EVAR is undocumented. This case report describes a unique instance of self-expanding iliac stent migration during TEVAR which pinched the thoracic aortic endograft causing functional aortic coarctation.
