Abstract
Here we report a 70-year-old man who underwent surgery for a dissecting thoracic aortic aneurysm and an infected left femoral artery aneurysm. The patient underwent ascending aortic replacement for type A acute aortic dissection 1 year earlier. He experienced unexpected chest pain and pyrexia. Additionally, a left inguinal reddish swelling, which had been previously diagnosed as a femoral artery aneurysm, had rapidly grown in size. A computed tomography scan revealed a new dissecting thoracic arch aortic aneurysm and a rapidly growing left femoral artery aneurysm; therefore, the patient was diagnosed with a dissecting thoracic aortic aneurysm and an infected left femoral artery aneurysm. During surgery, the left femoral artery aneurysm was excised prior to resternotomy. One lateral branch of a Y-graft was used for femoral artery reconstruction, and the other was used for inflow in cardio-pulmonary bypass; following this, total arch replacement was performed uneventfully. Excision of the infected aneurysm, usage of a rifampicin-soaked vascular prosthesis, and intravenous antibiotic administration for 4 weeks after surgery were effective in the treatment of the infected femoral artery aneurysm.
