In situ Reconstruction with Autologous Veins for the Treatment of Infected Abdominal Endografts: Single Center Experience.

Vascular graft infection is a feared complication with high mortality and morbidity rates. Complete excision with in situ repair is recommended. We report our experience with patients suffering of abdominal aortic endograft infection undergoing excision and in situ reconstruction with autologous vein. All patients who underwent excision of an abdominal aortic endograft and in situ reconstruction with autologous superficial femoral veins between April 2005 and June 2021 were retrospectively reviewed. Primary outcome measures were mortality and reinfection. Secondary outcome measure was patient morbidity. Fifteen patients (14 male; 93%) were included. Twenty percent of the index procedures (N = 3) were performed at our hospital, 80% (N = 12) were referred patients. Three aorto-enteric fistulae were seen. Staphylococci and enterococci were the most common pathogens (N = 8; 53%). In two out of six patients (33%) with an endograft with suprarenal fixation, the suprarenal fixation stent was left in situ. 30-day mortality rate was 6.6% (N = 1). Median follow-up time was 12 months (range 0-85). During follow-up, no reinfection was seen. Serious morbidity was witnessed in 2 patients (sepsis due to bowel leakage (N = 1), pneumonia (N = 2), hemodialysis (N = 1)). Eventration was the most common late morbidity observed (N = 5). Surgical treatment of vascular abdominal endograft infection by in situ reconstruction with autologous deep vein is a challenging procedure. If a multidisciplinary approach is applied and patients are centralized in experienced centers, acceptable mortality and morbidity rates can be achieved.
