Safety and feasibility of carotid artery stenting using a 6F guiding catheter via right distal radial artery access

ObjectiveThis study aimed to evaluate the safety and feasibility of carotid artery stenting (CAS) using a 6 F guiding catheter via right distal radial artery access.MethodsThe clinical data of 32 patients who underwent internal carotid artery C1 stenting via right distal transradial artery access (rdTRA) at the Department of Cerebrovascular Diseases, Beijing Anzhen Hospital, between January 2022 and December 2023, were retrospectively analyzed. Parameters including puncture time, X-ray irradiation time, exposure dose, surgical success rate, surgery-related cardiovascular and cerebrovascular complications, puncture site complications, and postoperative radial artery patency were recorded and assessed.ResultsThe procedural success rate of CAS through rdTRA was 100% (32/32). The time from operating room entry to successful puncture ranged from 3 to 36 min, with an average time of 18.56 +/- 7.63 min. X-ray exposure time ranged from 12 to 27 min, with an average time of 19.18 +/- 4.77 min. One patient experienced a procedure-related transient ischemic attack postoperatively, while another developed bruising along the radial artery course on the third postoperative day. During an out-of-hospital follow-up period averaging 1 to 29 months (median: 5.4 +/- 3.6 months), no cardiovascular or cerebrovascular events were reported. The radial pulse was palpable in all patients postoperatively and during the follow-up, with radial artery patency confirmed through patency testing.ConclusionCarotid artery stenting through rdTRA using a 6 F guiding catheter is a safe and feasible approach, demonstrating high procedural success and minimal complications.
