Single-stage total endovascular therapy for an aberrant right subclavian aneurysm

A 34-year-old woman who demonstrated an aberrant right subclavian artery aneurysm was referred to our hospital. Single-stage total endovascular therapy with preservation of the right vertebral artery using a surgeon-modified fenestrated stent graft was performed. Contrast-enhanced computed tomography on postoperative day 4 revealed the patency of the right vertebral artery with no evidence of endoleaks. The patient was discharged on postoperative day 6. Three years later, the patient had no adverse events. When an aberrant right subclavian artery aneurysm is anatomically suitable, single-stage total endovascular therapy for such an aneurysm is considered to be a feasible and appropriate minimally invasive treatment.
