PURPOSE: To determine whether exclusion of pseudoaneurysms with the use of a covered stent in prosthetic arteriovenous (AV) hemodialysis access grafts impacts the incidence of eventual AV graft infection. MATERIALS AND METHODS: Review of an interventional radiology database for prosthetic AV graft interventions involving stent deployment anywhere within the AV graft circuit revealed 235 interventions in 174 patients between November 2004 and December 2008. Incidence of AV graft infection was analyzed based on stent type (bare metal vs covered), location, and indication for stent deployment on a per-stent, per-procedure, and per-graft basis. RESULTS: A total of 16.3% of the stent-implanted AV grafts were eventually surgically excised as a result of graft infection. Covered stents used to treat an intragraft pseudoaneurysm were more commonly associated with subsequent graft infection compared with bare or covered stents deployed within the graft for other reasons: 42.1% versus 18.2% (P = .011). Stents deployed in an intragraft location were also associated with a higher incidence of graft infection compared with those deployed at the venous anastomosis or outflow vein: 26.9% versus 6.9% (P < .001). No significant difference was identified in infection rates between bare and covered stents. CONCLUSIONS: Covered stent exclusion of intragraft pseudoaneurysms demonstrated a significant correlation with eventual prosthetic AV graft infection.
