Neuro-Interventional Diagnosis and Treatment Using the Right Transradial Approach in Patients with Aberrant Right Subclavian Artery

Aberrant right subclavian artery (ARSA) is a common anatomical variation that presents challenges in cerebral angiography and interventions through the transradial approach (TRA). ARSA is often identified during surgery using the right transradial approach (R-TRA), and this necessitates a change in the approach.To assess the effectiveness and safety of neurological interventions using R-TRA in patients with ARSA.We retrospectively analyzed cases that underwent cerebral angiography and interventions at Huangpi District People's hospital from January 2023 to July 2023. Out of 335 cases, five patients with ARSA were identified.All five cases underwent diagnostic cerebral angiography via R-TRA. Two of the patients received interventions via R-TRA: one underwent right internal carotid artery balloon dilation angioplasty, while another underwent left vertebral artery stenting. No surgery-related complications were observed during these procedures.R-TRA proves to be a safe and effective option for neuro-interventional surgery in patients with ARSA.
