Abstract

BACKGROUND:Despite an overall surge in transradial access (TRA) for neurointerventional procedures, the feasibility and safety of TRA carotid artery angioplasty and stenting using balloon guide catheters (BGCs) through a short 8-Fr sheath have not been studied. In this study, we present our experience of using Walrus BGC through TRA for carotid artery stent placement.OBJECTIVE:To define the safety and efficacy of using a balloon guide catheter for carotid stenting by a transradial approach.METHODS:Our prospectively maintained retrospective database was reviewed, and consecutive patients were identified who underwent elective carotid artery stenting through TRA using Walrus BGC between January 2021 and June 2022. Demographics, procedural details including access site complications, the rate of radial to groin conversion, and procedure-related transient ischemic attack or stroke were reviewed.RESULTS:Twenty patients were identified who underwent carotid artery angioplasty and stenting through TRA Walrus BGC use; the mean age was 66 years (range 42-89), and 67% were male. A short 8-Fr sheath was used in all patients without any complications. Two of 20 patients required TRA conversion to transfemoral access, both secondary to severe spasm of the radial artery after initial access inhibiting further advancement of the Walrus BGC.CONCLUSION:Use of Walrus BGC by TRA through an 8-Fr sheath for carotid artery stenting is safe and feasible with a low rate of conversion to transfemoral access and no access site complications.
