Transradial access with Simmons guiding catheter for carotid artery stenting: Feasibility and procedural complications in a single-center experience

Abstract

Background

There is an increasing number of transradial approach (TRA) for carotid artery stenting (CAS), however, similar techniques and materials as for femoral access are used. We report the results of TRA lower profile technique for CAS using a 7 F Simmons guiding catheter, especially in terms of feasibility and procedural safety in a single center.

Materials and Methods

We retrospectively analyzed 68 consecutive patients with symptomatic extracranial carotid stenoses who underwent 75 CAS between January 2018 and December 2021. The success and crossover rate, procedural time, fluoroscopy, clinical outcomes, technical considerations, and procedural complications were analyzed.

Results

TRA CAS with Simmons guiding catheter was successful in 67/75 (89.3%) cases, with a 7 (9.3%) crossover rate. Fluoroscopy mean time was 15.8 minutes. Two forearm hematomas were described. No ischemic or surgical site complications were reported.

Conclusions

In our experience frontline TRA with a 7 F Simmons guiding catheter is feasible with high procedural success and a low rate of access site complications.
