Multicenter study reveals high technical success and safety in neurointerventional procedures using a guide catheter via transradial access.

Evaluate the effectiveness and safety of the Benchmark BMX81 guide catheter in transradial neurointerventions across multiple centers.
Conducted a multicenter, retrospective observational study in nine European neurointerventional centers.
Included adult patients undergoing procedures with the BMX81 as the primary guide catheter via a transradial approach.
Analyzed complications descriptively and defined technical success as completion of procedures using transradial access.
Achieved technical success in 289 out of 300 cases (96.3%).
Converted from radial to femoral access in four cases (1.3%) and aborted seven procedures (2.3%).
Reported infrequent minor complications such as radial artery spasm (1.7%) and minor forearm hematoma (5.3%).

Scarcia et al. (2026) studied this question.
