- Abstract: We report a case of surgery for an infectious left subclavian artery aneurysm in a patient with metal allergy. The patient was a 41-year-old man allergic to iron, silver, manganese, and chromium. He had received a Nitinol stent in the left subclavian artery at a previous hospital. One stent had fallen out during implantation, and was put away in the terminal aorta. Ten days after the left subclavian implantation, the patient developed left shoulder pain and fever, which continued for 2 weeks. Contrastenhanced CT scan revealed a pseudoaneurysm of the left subclavian artery and abdominal aortitis. The patient underwent left subclavian artery aneurysmectomy, aorto-left subclavian artery bypass using the great saphenous vein, and removal of the stents in the left subclavian artery and abdominal aorta. The surgery was performed through a median sternotomy with cardiopulmonary support. A contrast-enhanced CT scan taken on the 12th postoperative day revealed a pseudoaneurysm of the abdominal aorta, and the patient underwent abdominal aortic artery replacement surgery on the 14th postoperative day. The patient was discharged from the hospital on the 27th day after the first surgery. The treatment of an aneurysm should be selected according to the patient’s background as well as anatomical factors.
