OBJECTIVE: The aim of this study was to evaluate the early and mid term outcome of patients with aortic graft infection who underwent in-situ revascularisation with a silver coated prosthesis. MATERIAL: From January 2000 to December 2006, 24 consecutive patients (22 male, 2 female) with mean age 67 years were prospectively entered in this study of aortic graft infection at our single centre. Infection was managed with either total (n=19) or partial (n=5) excision of the infected graft and in- situ reconstruction with a silver coated prosthesis, Inter Gard Silver (IGSG). METHODS: The primary endpoint was recurrence of infection. Secondary endpoints were early and late mortality, peri-operative morbidity, primary graft patency, major amputation rates and patient survival. RESULTS: Fourteen patients had a primary graft infection, however 10 of 24 patients had graft infection secondary to aorto digestive (n=9) or aorto urinary (n=1) tract fistulas. Bacteriological cultures were negative in 8 (33%) patients. Most organisms cultivated where virulent and the majority of graft infections were polymicrobial (71%). Silver grafts were placed emergently in 6 (25%) patients. Mean follow up 32.5+/-31.0 months (range 2-78 months). Peri-operative morbidity and mortality were 46% and 21% respectively. Early interventions occurred in 6 (25%) patients and late secondary intervention were required in 3 (15.7%), caused by silver graft reinfection. The late mortality was 26%. CONCLUSION: In-situ reconstruction with the silver graft confirms similarity with other modalities. The greatest advantage for the silver graft is its ease of use but the risk of reinfection remains significant.
