Catheterization of the contralateral gate during endovascular aortic aneurysm repair is typically of little difficulty. However, on occasion it proves challenging. With the exception of grafts such as Nellix (Endologix Inc., Irvine, CA), which utilizes parallel stents with polymer endobags, and those that employ a unibody concept, such as the AFX (Endologix Inc., Irvine, CA), all modular grafts require this step. A difficult catheterization can often be facilitated by using different catheters, such as the Cobra, Van Schie (Cook Medical Inc., Bloomington, IN), or Sos (AngioDynamics Inc., Latham, NY) designs. Alternatively, a wire advanced up and over through the contralateral gate from the ipsilateral side can be snared allowing catheterization of the gate. This chapter describes a simple alternative buddy wire technique that facilitates rapid contralateral gate catheterization.
