Dialysis Graft InfectionSummary• Management strategy determined by:• Extent and timing of infection• Severity of systemic sepsis• Availability of other access sites• Total and subtotal excision most effective ineradicating infection but require catheter andnew access site• Partial excision & preservation preserves accesssites, avoid catheters but is associated with 20 –25% recurrence rate• Requires close monitoring• 6 weeks of culture directed antibioticsInfected Autogenous DialysisFistulas• Rare, S. aureus pre-dominant organism• Usually due to erosion of aneurysmthrough skin or necrosis at puncture site• Contamination vs Infection• Excision/reconstruction with or withoutinterposition graft preferred treatment• Recent reports of covered stents inabsence of gross infectionEndovascular Therapy ofAneurysmal AV fistulas• Shemesh, et al, J Vasc Surg,2011• 20 patients with aneurysmsand graftpseudoaneurysms, 6erosions (Viabahn)• 87% patency at 1 year withno infections• Shah, et al, J Vasc Surg, 2012• 24 patients, 8 witherosions, 3 failed due toinfection (Viabahn)107
Infected Autogenous DialysisFistulas• Fistula reduction andreconstruction• Wound closure overdrains• Depending on extentof resection, cathetermay be requiredSummary• Vascular access infection is a major causeof morbidity and expense in the dialysispopulation• Prevention is effective and should be apart of every institution’s program• Therapy should be individualized with thegoals of treating infection with minimalmorbidity while preserving access sitesand avoiding catheter usage whenpossible108
