Endovascular repair of cervical aortic arch aneurysm.

Cervical aortic arch (CAA) is a rare congenital anomaly of the aortic arch. Rarely, CAA is associated with aneurysm of the arch and great vessels. A 32-year-old male patient, previously in good health, presented with 2 weeks of severe chest pain. Radiographic evaluation revealed a CAA with aneurysmal dilation of the distal aortic arch. The aneurysm extended into the left subclavian artery. There was also marked angulation just distal to the aneurysmal portion. The aneurysmal arch and subclavian artery were repaired using a thoracic aortic endograft. An open axillary-to-axillary bypass was performed, and the left axillary artery was ligated proximally. This restored perfusion to the left upper extremity and effectively excluded the aneurysm sac. Immediately postoperatively, the patient's chest pain resolved, and he has remained symptom free. To the authors' knowledge, this is the first reported repair of a cervical arch aneurysm by endovascular technique.
