Abstract
Between August 2002 and September 2018, sixteen patients with infected aortic aneurysm （8 thoracic aorta, 6 abdominal aorta and 2 iliac artery） underwent the operation. They comprised 14 men and 2 women, and a mean age was 73 years old. Microorganisms causing infected aortic aneurysms were 3 MRSA, 3 MSSA, 2 E.coli, 2 Campylobacter sp, 1 MRCNS, 1 CNS, 1 Streptococcus pneumoniae, 1 Pasteurella multocida, 1 Bacteroides thetaiotaomicron and 1 unknown. Surgical treatment were in situ graft replacement with rifampicin soaked vascular prosthesis and greater omental flap coverage in six, in situ graft replacement with rifampicin soaked vascular prosthesis in three, in situ graft replacement in two, endovascular repair in two, in situ graft replacement with greater omental flap coverage in one, closure of iliac artery with extraanatomical bypass in one and greater omental flap coverage in one. There were two 30-day death, three inhospital death and two remote death. None was reoperated due to recurrence of infection in remote alive patients. Although the definitive surgical treatment for infected aortic aneurysm is in situ graft replacement with rifampicin soaked vascular prosthesis and greater omental flap coverage, endovascular aortic repair is effective for old patients and infected aortic aneurysm with aorto-bronchopulmonary or aorto-enteric fistula.
