Transradial access of neuro-endovascular interventions with aberrant right subclavian arteries: Case series and literature review:

Transradial artery access (TRA) is increasingly favored in neuro-endovascular procedures due to its lower complication rates. However, in patients with an aberrant right subclavian artery (ARSA), a congenital vascular anomaly, catheter navigation can become technically challenging. We report three such cases: one required conversion to transfemoral access, while the other two were successfully managed using alternative strategies such as left distal radial access or careful catheter manipulation. Including our cases and 11 from the literature, 3 out of 14 required access conversion. These findings highlight the importance of thorough preoperative imaging and the need for flexible procedural planning when ARSA is present, to ensure both safety and procedural success.

Impression: TRA can be successfully performed in ARSA cases with careful planning and technique. Preoperative assessment and flexible access strategies help maximize success and minimize the need for conversion.
