    Abstract:
    BACKGROUND AND PURPOSE: Placement of a large-bore guiding sheath or catheter into the common carotid artery (CCA) is crucial in transbrachial carotid artery stenting (CAS). Herein, we describe technical tips for the navigation of a 6-French guiding sheath into the CCA using a tri-axial catheter system in transbrachial CAS. MATERIALS AND METHODS: A total of 27 patients underwent transbrachial CAS. For the right side, a 6-French straight guiding sheath was navigated directly into the CCA using a tri-axial catheter system, with a 4-French Simmons catheter placed through a 6-French straight guiding catheter. For the left side, a 6-French Simmons guiding sheath was navigated into the CCA using a tri-axial catheter system, with a 4-French Simmons catheter placed through a 6-French Simmons guiding catheter. After the placement of a 6-French guiding sheath into the CCA, CAS was performed under distal filter or balloon protection. RESULTS: Fifteen patients had a right carotid stenosis and 12 patients had a left carotid stenosis. The 6-French guiding sheath was safely placed with ease and provided adequate stabilization for CAS. All procedures were successfully performed without any complications. CONCLUSION: The use of a tri-axial catheter system for the navigation of a 6-French guiding sheath into the CCA appears safe and efficient, allowing transbrachial CAS, with 6-French guiding sheath stabilization, to be performed without any complication.
