Background: Abdominal aortic stent graft infection (AAGI) is a severe complication. The optimal management of AAGI remains unclear. This study provides updated results of bilateral axillofemoral bypasses (AFBs) for patients with AAGI. Patients and Methods: In total, 31 patients (25 men; mean age, 67.1 years) with AAGI treated using AFB between January 2006 and April 2020 were included. Overall, the mean follow-up duration was 24 months (range, 1-72). In the 23 patients who survived the post-operative period, the mean follow-up duration was 32 months (range, 12-72). Results: Thirty-day and in-hospital mortality rates was 16% and 26%, respectively. The 12-month primary and secondary patency rates for the AFB graft were both 91%. In total, seven (30%) patients received re-interventions such as thrombectomy and balloon angioplasty. No amputation was required during follow-up. Culture results were positive in 87% of pre-operative cultures and 84% of intra-operative cultures. Staphylococcus aureus was the most prevalent pathogen, with four cases of methicillin-resistant Staphylococcus aureus and one each of vancomycin-resistant enterococci, carbapenem-resistant Klebsiella pneumoniae, and carbapenem-resistant Enterobacteriaceae. In-hospital mortality rate was 57% in patients with drug-resistant pathogens. Conclusions: Reconstruction with bilateral AFB and stent graft removal in patients with AAGI is a feasible treatment modality and provided an acceptable patency rate and low amputation rate. Additional studies investigating long-term results and the optimal treatment of AAGI are required.
