Background: Surgical site infections (SSIs) constitute one of many major complications after aortic aneurysm surgery and its details and outcome have not been evaluated extensively. This research evaluates the incidence and outcome of SSI and graft infection in open and endovascular abdominal aortic aneurysm surgery.Patients and Methods: A retrospective study was performed, including all patients who underwent surgery for aortoiliac aneurysmatic disease between January 2000 and December 2016 in the Amphia Hospital, Breda, The Netherlands. Surgical site infections were defined in accordance with criteria of the U.S. Centers for Disease Control and Prevention (CDC). Aortic graft infection was diagnosed by a combination of computed tomography imaging and microbiologic results.Results: Between January 2000 and December 2016, 845 patients (mean age, 72.80 ± 7.15 y, 86.3% male) underwent abdominal aneurysm surgery (477 endovascular, 368 open). The total SSI rate was 3.1% (12 endovascular [2.5%], 14 open [3.8%], p = 0.318) with 0.8% deep SSI (26.9% of SSIs). No difference in SSIs was found between acute and elective surgery (2.9% vs. 3.1%, p = 1.000). Patients with SSI had a longer duration of stay (mean, 27.65 ± 30.74 d vs. 9.79 ± 12.50 d, p < 0.0001) but no difference in 30-day or 1-year mortality. Twenty-four graft infections occurred (4.3% of open vs. 1.7% of endovascular surgery, p = 0.023) of which 20 (83.3%) required surgery. Two-year mortality was higher when graft infections occurred (33.3% vs. 16.3%, p = 0.046). Surgical site infections (odds ratio [OR] 7.10, 95% [CI] 2.10-23.98) and mycotic aneurysms (OR 9.38, 95% CI 1.78-54.19) are independent determinants for graft infections.Conclusion: This study shows that SSIs after endovascular aortic surgery are as common as after open aortic surgery. Furthermore, this study supports the concept that aortic graft infection is highly associated with SSIs and mycotic aneurysms. Studies evaluating the prevention or early diagnosis of graft infection after SSIs through intensified imaging follow-up or even long-term antibiotic treatment should be considered.
