: The optimal surgical management for primary infected abdominal aortic aneurysm (IAAA) is controversial. Here, we report the early and long-term results of surgical treatments with the resection of the IAAA and in situ graft reconstruction with pedicled omental coverage that was performed at out hospital. : Between 2010 and 2017, 27 consecutive patients (26 males, 1 female, median age 69 years) with IAAA were surgically treated with the resection of the IAAA, in situ graft reconstruction and covered with a pedicled omental flap. Perioperative and long-term outcomes were reviewed retrospectively by medical records. : Clinical manifestations, including pyrexia, fever and abdominal pain, were observed during the treatment of the patients. Aneurysm excision and in situ graft reconstruction with omental coverage were performed for all cases. In 13 cases (48.1%), tissue culture was positive. The antibiotic was administered intravenously for 9 to 47 days (median 18 days) postoperatively, and after confirming the reduction of the inflammatory response, it was administered as oral agents for 24 to 443 days (median 169 days).There was no perioperative death or re-infection. Perioperative complications were found in 8 cases (29.6%) of minor spinal cord infarction, ileus, chylous ascites, and cholangitis due to choledochlithiasis. During the observation period of median 1,147 days, there was no recurrence of infection, graft infection, or disease-related death. There were six deaths due to other diseases. And the overall survival rate was 76.2%. : According to our study, the long-term outcomes of surgical treatment with in situ graft reconstruction for IAAA were considered satisfactory.
