A subclavian artery aneurysm associated with aortitis syndrome.
We performed surgery on a 61-year-old woman who had increasingly severe right shoulder pain and paresthesia in her right upper extremity as a result of a large right subclavian artery aneurysm. She had suffered from aortitis syndrome for 10 years for which she was treated with steroids and had multiple arterial lesions, including bilateral subclavian artery aneurysms, abdominal aortic aneurysm and obstruction of bilateral superficial femoral arteries. The right subclavian artery aneurysm measured 4 cm in diameter and rupture appeared imminent, prompting surgical therapy. Via the supraclavicular incision approach and additional partial sternotomy, the aneurysm was excluded and the brachiocephalic to right axillar arterial bypass was set up using an extended polytetrafluoroethylene graft. The patient recovered without complications and a subclavian artery aneurysm demonstrated by computed tomography was thrombosed 1 month after surgery. In conclusion, we recommend the exclusion technique to treat subclavian artery aneurysms in cases in which aneurysmectomy is likely to injure adjacent veins and nerves.
