[Distal Radial Approach for Neuroendovascular Procedure:Initial Experience]

Area of Science:

• Neurosurgery
• Vascular Surgery
• Interventional Radiology

Background:

• The distal radial approach (DRA) is an emerging technique in vascular access.
• Its application in neuroendovascular procedures via the anatomical snuffbox is not well-established.

Purpose of the Study:

• To evaluate the initial experience and feasibility of using the DRA via the anatomical snuffbox for diverse neuroendovascular interventions.
• To assess the safety and efficacy of this novel approach.

Main Methods:

• Retrospective analysis of 16 patients undergoing neuroendovascular procedures using DRA via the anatomical snuffbox.
• Procedures included diagnostic cerebral angiography, aneurysm coiling, carotid stenting, and embolization of AVMs and subdural hematomas.
• Successful catheterization and procedural outcomes were recorded.

Main Results:

• Successful vessel catheterization was achieved in 15 out of 16 patients (93.75%).
• One patient required conversion to a conventional transradial approach.
• Procedures performed included cerebral angiography, aneurysm embolization, carotid stenting, and embolization for AVM and chronic subdural hematoma.
• Favorable operability, excellent hemostasis, and no approach-related complications were observed.

Conclusions:

• The distal radial approach via the anatomical snuffbox is technically feasible for a range of neuroendovascular procedures.
• DRA offers a potentially less invasive alternative to traditional vascular access methods in neuroendovascular interventions.
