Treatment of aneurysmal aberrant right subclavian artery with triple-barrel stent graft.

Aneurysmal evolution of an aberrant right subclavian artery (ARSA) is an operative indication. Endovascular treatment is a minimally invasive procedure, which offers good short-term and midterm results. We describe a case of a 9-cm diameter ARSA aneurysm in a symptomatic man, treated with the triple-barrel technique using a thoracic aortic stent graft combined with surgical and endovascular revascularization of the supra-aortic trunks. Postoperatively, the patient developed a type III endoleak which was covered. The triple-barrel technique has been a proposed treatment approach for complex aortic arch pathologies and remains a less invasive option when compared with open surgery.
