Successful treatment of a Salmonella aortic arch aneurysm.

A 52-year-old man hospitalized for hoarseness and chest pain was found in chest computed tomography to have an impending aortic arch aneurysm rupture. Laboratory studies showed the presence of severe inflammation. Based on a clinical diagnosis of infected aortic arch aneurysm, we conducted total arch replacement. Salmonella was identified in the aneurismal wall and antibiotics were administered long-term. The postoperative course was uneventful. The patient was discharged on postoperative day 48. He has remained afebrile and asymptomatic in the 10 months since surgery but continues to take 300 mg/d of oral levofloxacin.
