Background Radial artery occlusion (RAO) is a relatively common but benign complication following transradial endovascular approaches. Transradial access in the occluded vessel has been described as safe and feasible in recent literature. Radial artery thrombectomy offers a potential strategy for re-access.

Methods This retrospective study at a single institution includes adult patients undergoing transradial neurointerventional procedure who experienced acute radial artery occlusion between 2021–2023. Cases were reviewed for medical history and details of intervention.

Results Seven patients were identified and included for review. Average patient age was 52.9 years. Most patients suffered ruptured aneurysm (n=4), and other diagnoses included carotid stenosis, vertebral stenosis, and tumor embolization. Patients underwent a range of 1–3 prior catheterizations before undergoing radial artery thrombectomy. The days between the last catheterization and thrombectomy ranged from 2–10 days. This report includes details to illustrate this technique.

Conclusion This case series highlights the safe use of mechanical thrombectomy of acute radial artery occlusion for re-access in neurointervention. This study further provides a step-by-step instruction for this approach.
