Right subclavian artery aneurysm: report of a case.

A subclavian artery aneurysm is relatively rare in comparison with other peripheral aneurysms. Surgical repair should be considered regardless of size and location, because thromboembolism or rupture can occur when a small aneurysm is untreated. We describe the management and surgical treatment in a patient with a right subclavian artery aneurysm. Surgical repair included the ligation of the right vertebral artery and reconstruction of the subclavian artery through an upper partial median sternotomy with right supraclavicular extension. Successful repair of the aneurysm was accomplished and the patient's postoperative course was uneventful with no medication.
