Significant life-threatening complication can arise when fracture and migration of the stent grafts used for treating AV access occur. Herald bleed with a previously placed stent graft may be a harbinger of future rupture. Complications appear less likely when stent grafts are used to treat stenosis; however, when complications occur, access site salvage is rare. Surgical revision in the case of pseudoaneurysm should be considered for access preservation.
