Purpose: To describe a contralateral femoral approach for iliac branch device implantation using a steerable sheath in the setting of an existing bifurcated stent-graft. Technique: The method is demonstrated in an 80-year-old man who developed a 4-cm iliac aneurysm 3 years after implantation of an Endurant bifurcated stent-graft. Both femoral arteries were cannulated after surgical cutdown. The steerable sheath was advanced from the contralateral side over the neobifurcation of the bifurcated stent-graft. A 0.014-inch Roadrunner wire was used as a through-and-through wire to stabilize the curve of the sheath and to get proper push. The bridging stent-graft for the iliac branch was advanced over this sheath to seal the iliac aneurysm. During the entire procedure, the sheath was stable over the neobifurcation without pulling it down. Conclusion: The contralateral femoral approach for iliac branch graft implantation is feasible in cases with an extant bifurcated stent-graft using a steerable sheath and a through-and-through wire.
