RESUMO
Endovascular stent-graft repair is emerging as the treatment of choice for complicated type B aortic dissection. In this report we describe a patient who presented with type B aortic dissection involving a right-sided aortic arch (RAA), a rare congenital vascular anomaly. The initial aggressive medical treatment proved unsuccessful due to false aneurysm expansion. Given the greater complexity of conventional surgical repair and the limited experience with this rare malformation, endovascular repair was preferred and successfully performed. We report the first case of endovascular repair of type B dissection involving RAA, confirming that endovascular treatment is technically feasible also when the dissection involves this unusual vascular malformation.
