Technical and anatomical considerations in aortic stent graft infolding following thoracic endovascular aortic repair

Thoracic endovascular aortic repair (TEVAR) is the preferred intervention for thoracic aortic pathology, offering favorable outcomes compared with open repair. Aortic graft infolding, although rare with an incidence of 0.4% to 3%, can pose significant clinical challenges. We present three patients who developed infolding post-TEVAR using the Terumo Relay Pro endograft, detailing their presentation, management, and outcomes. This case series, along with a review of the literature, provides insight into aortic endograft infolding after TEVAR and helps refine the risk stratification and management protocols.
