Buttress technique to insure accurate placement of AneuRx stent-grafts in patients with complex anatomy.
OBJECTIVE
To describe a technique that prevents caudal displacement of the AneuRx stent-graft during removal of the nose cone and runners.


METHODS
The buttress technique uses a 16-F sheath positioned from the contralateral femoral approach at the inferior edge of the endograft's main body to provide safe retraction of the runners and the nose cone and accurate endograft deployment.


CONCLUSIONS
If accurate deployment of the stent-graft according to the manufacturer's directions is not possible, this buttress technique can insure proper positioning. It adds no additional time or equipment to the procedure, and it appears to be a safe and easily applied maneuver.
