Thoracic endovascular aneurysm repair for coarctation of the aorta with dissecting aortic aneurysm: A rarity

Coarctation of Aorta and Post-Stenotic Dissecting Aortic Aneurysm Successfully Treated with Endovascular Stent

Coarctation associated with a dissected aneurysm is uncommon and has an incidence of less than 1%. There are few reports describing treatment of this condition with stent graft. Challenging as it may be, endovascular treatment of complex cases has become the preferred modality especially when the anatomy is amenable. We describe the case of a 36-year old male, who suffered a car accident and was diagnosed with acute type B aortic dissection (ATBAD). CT-scan revealed a coarctation associated with a large dissected aneurysm (11cm). Complexity of pathology and high risk of rupture required immediate intervention. Open repair necessitates extensive surgery with a considerable risk of morbidity and mortality. We decided to perform an endovascular repair and subsequentially the patient was successfully treated with stent graft deployment, showing durable early-midterm results. Patient remains asymptomatic to this day and CT-scan at 3-year follow-up revealed a reduced and thrombosed aneurysm.
