Abstract

A 76-year-old man with an ascending arch and proximal descending aortic aneurysm underwent a complex aortic replacement through a sternotomy with ligation of a right aberrant subclavian artery (RASA) distal to the right vertebral artery. The second-stage procedure was performed with a stent-graft deployed within the elephant trunk. At 6- and 12-month follow-up, the RASA was opacified by the patent right vertebral artery. Under ultrasound guidance, the patient's RASA stump was occluded by coils. Management of an RASA during complex hybrid stent-graft procedures is discussed.
