Outcomes of Percutaneous Access to the First Versus Third Segment of Axillary Artery During Aortic Procedures.

Percutaneous access with vascular closure devices at the first or third axillary artery (AXA) segments during aortic procedures is burdened by a negligible risk of open conversion. Local complications with the percutaneous axillary approach are infrequent and solvable by complementary endovascular interventions. First and third AXA segments are both amenable to access with excellent results, but larger sheaths (12F) perform better in the wider first AXA segment. In this setting, bailout stenting does not appear to be associated with mid-term stent occlusion.
