Department of Cardiovascular and Endovascular Surgery, Arizona Heart Institute and Arizona Heart Hospital, Phoenix, AZ This paper describes a case of aortic arch pseudoaneurysm treated with stent graft 2 years after aortosubclavian bypass repair of a subclavian artery aneurysm. An 84-year-old man presented with back pain. Two years before, he had had a left subclavian artery aneurysm repaired with aortosubclavian bypass. Upon examination by computed tomography (CT) scan and angiography he was found to have a bovine arch configuration, a 7-centimeter pseudoaneurysm arising from the stump of the native subclavian artery, a patent aortosubclavian bypass, and a left hemothorax. A 37 mm by 10 mm Gore Excluder thoracic graft was introduced into the right femoral artery cutdown and deployed across the arch, excluding the pseudoaneurysm and preserving the brachiocephalic vessels. Follow up CT scan at 1 year shows exclusion of the pseudoaneurysm. The patient continues to do well 1 year after implantation without evidence of endoleak. In the presence of unusual anatomical characteristics, endoluminal stent graft repair can be successfully performed across the aortic arch.
