BackgroundWe present a series of patients who underwent in situ total aortic arch replacement for infected distal aortic arch aneurysms.MethodsBetween 2002 and 2013, 9 patients with infected distal aortic arch aneurysms underwent total aortic arch replacement using antegrade selective cerebral perfusion. There were 4 male and 5 female patients with a mean age of 72.7±9.0 years. All patients had penetrating atherosclerotic ulcer in the distal aortic arch, which formed saccular aneurysms. Four patients had preoperative hoarseness. Maximum preoperative white blood cell count was 10,211±4375/μL, and mean serum C-reactive protein concentration was 12.7±7.2 mg/dL. Causative microorganisms were identified by blood culture or aortic wall culture and were as follows: Candida albicans, Pseudomonas aeruginosa, Edwardsiella tarda, Streptococcus dysgalactiae, Listeria monocytogenes, Staphylococcus aureus (2 cases), and unknown (2 cases). Radical debridement with in situ total aortic arch replacement was performed in all patients, followed by the omental flap grafting in 7 patients. All surgery was performed on an urgent or emergency basis.ResultsAverage cardiopulmonary bypass time and lower body circulatory arrest time were 199.7±50.7 minutes and 66.6±13.8 minutes, respectively. There was no in-hospital mortality, but 1 patient died of asphyxia 5 months after hospital discharge. Freedom from recurrence of infection was 100%.ConclusionsSurgical treatment with the combination of radical debridement with in situ total aortic arch replacement using antegrade selective cerebral perfusion and omental flap grafting was a reliable procedure for the treatment of infected distal aortic arch aneurysms.Copyright © 2014.
