[Transradial approach in neuroendovascular procedures]

Area of Science:

• Neurology
• Vascular Surgery
• Interventional Radiology

Background:

• The transradial approach is increasingly utilized in endovascular procedures.
• Its application in neuroendovascular interventions requires specific technical considerations.
• Evaluating its safety and feasibility is crucial for expanding its use.

Purpose of the Study:

• To assess the safety and feasibility of the transradial approach for neuroendovascular procedures.
• To educate neurosurgeons and neuroradiologists on its capabilities, limitations, and technical aspects.
• To analyze factors influencing the effectiveness of transradial access in neurointerventions.

Main Methods:

• Retrospective analysis of 270 patients undergoing transradial neuroendovascular procedures (January 2015 - December 2019).
• Detailed description of catheterization techniques and instrument selection for radial access.
• Categorization of procedures into diagnostic (75.2%) and surgical (24.8%).

Main Results:

• High accessibility rates for target vessels: right vertebral (100%), both common carotids (100%), left common carotid (100%), left internal carotid (92%).
• Left vertebral artery catheterization utilized a left-sided radial approach.
• Low rates of conversion to femoral approach (2.6%) and asymptomatic radial artery occlusion (3.7%).

Conclusions:

• The transradial approach is demonstrated to be safe and feasible for neuroendovascular procedures.
• This technique offers a viable alternative for accessing cerebral vasculature.
• Neurosurgeons and neuroradiologists can effectively utilize this approach with proper technique.
