Abstract

Post-coarctation of the aorta (CoA) pseudoaneurysms is a complication of open repair. Thoracic endovascular repair (TEVAR) is feasible but complicated by proximity to the supra-aortic trunks and severe arch angulation. We describe three cases of post-CoA pseudoaneurysms treated with custom-made Relay stent grafts (Vascutek, Scotland). Technical and clinical success was achieved in all three cases with no mortality, morbidity, endoleaks, or complications. In all three, pseudoaneurysm sac shrinkage was observed at the follow-ups; in one case, there was complete resolution. Redo open surgery is challenging because of adhesions of the thoracic cavity and associated morbidity and mortality. TEVAR is less invasive and offers fewer complications. Custom-made modifications overcome difficult anatomies including short landing zones and diameter variability.
