Use of a Steerable Sheath for Antegrade Catheterization of a Supra-aortic Branch of an Inner-Branched Arch Endograft via a Percutaneous Femoral Access

Abstract

Purpose: To describe the use of a steerable sheath from a femoral access for antegrade catheterization of the left common carotid artery (LCCA) in an inner-branched arch endograft. Technique: This technique is demonstrated in a patient with residual aortic dissection after replacement of the ascending aorta for acute type A aortic dissection. He presented 4 years later with aneurysmal degeneration of the thoracoabdominal aorta and a proximal tear located in the aortic arch. A 2-stage hybrid approach was devised to treat the patient. An axilloaxillary crossover graft (left to right) with plug occlusion of the innominate artery was performed initially. Later, a dual-branched custom-made device was implanted. To avoid an additional LCCA cutdown for retrograde branch access, an 18-F steerable sheath was used through a percutaneous femoral access. Two wires were delivered within the steerable sheath: the first one was directed into the left subclavian artery to stabilize the sheath position in the ascending aorta; the second wire was used to catheterize the first inner branch and the LCCA to deploy the covered bridging stent. Conclusion: Transfemoral access to catheterize antegrade branches for supra-aortic vessels is feasible using a large steerable sheath in branched endovascular arch repair.
