RESUMO
PURPOSE: To report a rare case of giant aortic coarctation (CoA)-related descending thoracic aneurysmal degeneration, complicated by an acute aortic dissection. CASE REPORT: A 57-year-old man referred with acute chest pain to the emergency department. A computed tomography angiography (CTA) revealed a CoA with a giant post-stenotic descending thoracic aneurysm (14 cm) and a concomitant left subclavian artery (LSA) aneurysm, complicated by an acute type B aortic dissection. A single-stage hybrid procedure was planned in an urgent setting. Initially, a left common carotid-to-left subclavian artery (LCCA-LSA) bypass was performed to gain a suitable proximal landing zone, the procedure was then completed with 3 thoracic endografts and 1 aortic dissection stent through a percutaneous femoral approach. The patient was discharged in postoperative day 8th without complications; the CTA performed at 1 month demonstrated patency of supra-aortic and visceral vessels, dilation of CoA site and exclusion of the false lumen. CONCLUSIONS: CoA is a congenital malformation rarely found in adults that may represent a challenge for the surgeon, especially when combined with a complication like an acute aortic dissection. This case shows that a hybrid approach is a safe and feasible treatment option even in such complex anatomies.
