Evolution of Transradial Access for Mechanical Thrombectomy-A Single Center Experience

Area of Science:

• Neurointerventional radiology
• Vascular neurology
• Medical device innovation

Background:

• Transradial access (TRA) is increasingly adopted by neurointerventionalists.
• Hesitation persists regarding its application in mechanical thrombectomy (MT).

Purpose of the Study:

• To evaluate the evolution and effectiveness of TRA for MT.
• To assess the impact of procedural experience and specialized equipment on MT outcomes via TRA.

Main Methods:

• Retrospective analysis of 53 patients undergoing TRA for MT.
• Chronological analysis to evaluate the learning curve and impact of experience.
• Assessment of a novel radial-specific guide catheter's influence.

Main Results:

• Significant reductions observed in contrast use, procedure time, fluoroscopy time, and puncture-to-recanalization time with increasing experience.
• Introduction of a radial-specific catheter led to statistically significant improvements in all measured parameters, including a higher recanalization rate.
• A trend toward improved thrombolysis in cerebral infarction (TICI) ≥ 2b recanalization rates was noted over time.

Conclusions:

• Transradial access is a safe and effective method for endovascular access in MT.
• Procedural experience enhances the efficacy and efficiency of TRA for MT.
• Radial-specific catheters improve device selection and lesion access, potentially enhancing MT outcomes.
