Pseudoaneurysm is a known complication of arteriovenous grafts in chronic hemodialysis and can result in graft disruption or thrombosis if left untreated. This study evaluated the safety and efficacy of endovascular repair with Wallgraft endoprosthesis (Boston Scientific, Inc, Watertown, Mass) in a porcine arteriovenous graft (AVG) pseudoaneurysm model. Materials and Methods: Bilateral groin AVG pseudoaneurysms (n = 18) were created with an oversized Dacron interposition graft within a polytetrafluoroethylene femoral AVG in nine domestic swine and allowed to mature 28 +/- 4 days (standard deviation). Transluminal placement of Wallgraft was performed to exclude the pseudoaneurysm from the AVG circulation. Hemodialysis was performed (400 mL/min x 1 hour, with intravenous heparin 30 units/kg) every 4 days for a total of 6 weeks via 15-gauge needles in the treated AVG pseudoaneurysm site. Arteriography and duplex ultrasound scan were performed to determine AVG patency and pseudoaneurysm flow. Histologic evaluation was performed to determine Wallgraft morphology. In vitro pulsatile flow chamber was used to determine maximal flow volume without peri-Wallgraft endoleak.
