Introduction The transradial (TRA) approach for neurointerventional procedures is increasingly being used given its technical feasibility and safety. However, catheter trackability and device issues are reported barriers to TRA adoption.

Aim of Study To describe the technical feasibility and success of using the Zoom RDL Radial Access for NeuroInterventional procedures

Methods This is the first report describing the technical feasibility and success of using the

Zoom RDL Radial Access for neurointerventional procedures from October 2022 to

December 2022 in a single-center institution.

Results We included 25 cases (mean age 61.2 ± 18.2 years; 80.0% female; 60.0% Black).

The most common pathologies were strokes (28.0%) and aneurysms (28.0%). The most common procedure was endovascular thrombectomy (28.0%). We used the

TRA approach in 21 cases (84.0%), including distal radial/snuffbox access (36.0%).

The radial diameter was greater than 2 mm for all cases who underwent the TRA approach. An intermediate catheter was used in 16 cases (64.0%). Technical access success was achieved in 23 cases (92.0%); 1 case required conversion from TRA to transfemoral approach (4.0%) and 1 case required conversion to a different guide catheter (4.0%). There were no access site complications, 1 intracerebral hemorrhage (4.0%), and 1 guide catheter-associated thrombus (4.0%).

Conclusion The use of Zoom RDL Radial Access System is technically feasible and effective for complex neurointerventional procedures with low complication rates.
