Updates in Radial Access for Neurointervention: Feasibility, Innovations, and Future Directions.

Area of Science:

• Neurology
• Interventional Radiology
• Vascular Surgery

Background:

• Radial access, originating from cardiovascular procedures, is increasingly adopted in neurointervention.
• It offers a patient-preferred alternative to femoral access, with benefits like faster ambulation and fewer complications.
• The technique is effective for complex neurovascular anatomy and specific procedures such as mechanical thrombectomy.

Purpose of the Study:

• To review the latest evidence on radial access in neurointervention.
• To highlight technical advancements, patient selection, clinical applications, and complication management.
• To emphasize the growing feasibility and utility of radial access in neurovascular procedures.

Main Methods:

• Review of current literature and meta-analyses on radial access in neurointervention.
• Focus on technical tips, patient selection criteria, and clinical applications.
• Discussion of advancements in radial access techniques and hemostasis.

Main Results:

• Radial access demonstrates high technical success rates (approx. 97%) with low crossover rates (approx. 5%).
• It is associated with minimal access-site complications compared to traditional femoral access.
• The approach is effective for challenging aortic arch anatomy and posterior circulation interventions.

Conclusions:

• Radial access is a safe, feasible, and effective approach for a growing range of neurointervention procedures.
• Technological and technical advancements continue to expand its applicability and improve outcomes.
• It represents a significant advancement in neurovascular care, offering benefits for both patients and clinicians.
