AI Article Synopsis
- Iliac arterial disease, unfavorable anatomy, and prior stenting complicate access in endovascular abdominal aortic repair (EVAR) and thoracic aortic repair (TEVAR).
- Some experts suggest placing an iliac stent before T/EVAR for patients with poor iliac access, but the complications related to this approach are not well-documented.
- This case report details a specific incident of iliac stent migration during TEVAR that resulted in the stent pinching the thoracic aortic endograft, leading to functional aortic coarctation.
Article 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.
