Abstract

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

Methods This is the first report describing the technical feasibility and performance of using the ZoomTM RDL Radial Access Platform (Imperative Care, Inc., Campbell, CA) in 29 patients who underwent neurointerventional procedures from October 2022 to January 2023 in a single-center institution.

Results Mean age of the study population was 61.9 ± 17.2 years, 79.3% were male (23/29), and 62.1% were Black (18/29). The most common procedures were stroke thrombectomy (31.0%, 9/29) and aneurysm embolization (27.6%, 8/29). All the stroke thrombectomy procedures were successfully performed; first-pass effect rate (mTICI ≥2c in one pass) was achieved in 66.7% (6/9) of cases. We used TRA in 86.2% of cases (25/29), including distal radial/snuffbox access in 31.0% (9/29) of cases. The radial diameter was > 2 mm for all cases. An intermediate/aspiration catheter was used in 89.7% (26/29) of cases. Access success was achieved in 89.7% of cases (26/29); two cases required conversion from TRA to transfemoral approach (6.9%) and 1 case required conversion to a different guide catheter (3.4%). There were no access site complications or other ZoomTM RDL-related complications. One intracerebral hemorrhage, and one procedure-related thrombus were observed.

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