Catheterization of the contralateral gate on the main body of aortic stent grafts is an important step of the endovascular aneurysm repair procedure. This step can be readily accomplished with appropriate pre- and intraprocedural planning. In cases in which the catheterization is challenging, several techniques can be utilized to overcome this difficulty. A Glidewire (Terumo Medical) together with a variety of catheters can be employed, most commonly either a hockey stick (e.g., Berenstein (AngioDynamics Inc., Latham, NY) and Kumpe (Cook Medical Inc., Bloomington, IN)) or reverse curve (e.g., Sos 1/2, Cook Medical Inc., Bloomington, IN) configuration. Occasionally, other catheters, such as a Van Schie (Cook Medical Inc., Bloomington, IN), may be useful when the gate is located away from the end of the contralateral sheath. This chapter delineates the Turret technique for rapid gate catheterization.
