Aims: The aim of our study was to demonstrate the feasibility and safety of the distal transradial approach (DTRA) for carotid artery stenting (CAS).
Methods and results: We included 209 consecutive patients (151 Trans-Radial Access (TRA) and 58 DTRA) treated in a single center by CAS with cerebral protection between 2016 and 2018. DTRA punctures were done by ultrasound guidance, and the carotid artery cannulations were performed using a 6.5 F coronary sheathless guiding catheter. The groups showed similar demographic profile regarding age, gender and comorbidities, however the proportion of symptomatic patients was significantly higher in the DTRA cohort (p < 0.001). Procedural success rate was similarly high in both groups, while the overall complication rate was very low, with no major adverse events and only a few vascular complications. The cannulation times were similar, while the overall procedure length was slightly higher in the DTRA group. The cumulative X-ray dose was similarly low regardless the access used.
Conclusions: DTRA is a safe and effective alternative of conventional trans-radial approach for CAS, with a potential to further improve the patient comfort.
