Feasibility and Safety of 8F Guiding Catheter Navigation in Transradial Neurointervention for Unruptured Intracranial Aneurysms: A Propensity Score–Matched Comparison of Sheath-Based versus Sheathless Approaches

Key Points

• Investigate the feasibility and safety of using an 8F guiding catheter in transradial access for treating unruptured intracranial aneurysms.
• Conducted a propensity score-matched comparison of sheath-based and sheathless approaches.
• Evaluated complications related to radial artery access during the procedure.
• The use of the 8F guiding catheter was feasible in the transradial approach.
• There was a reduction in the risk of radial artery occlusion and spasm with the 8F sheath.
• No increased incidence of complications at access or non-access sites was observed.
