Objective:
To evaluate safety and feasibility of transradial approach for neuroendovascular procedures and to familiarize neurosurgeons and neuroradiologists with the capabilities and limitations of this approach, as well as technical features influencing its effectiveness.
Material And Methods:
A retrospective analysis was performed in 270 patients who underwent transradial neuroendovascular procedures between January 2015 and December 2019. Diagnostic and surgical interventions were performed in 203 (75.2%) and 67 (24.8%) patients, respectively. The authors comprehensively describe catheterization technique and choosing the instrument for effective and safe transradial access.
Results:
The right vertebral and both common carotid arteries were the most accessible for selective catheterization (100% of cases). The left common carotid artery was catheterized in all cases, the left internal carotid artery - only in 92% of cases. If catheterization of the left vertebral artery was necessary, we used the left-sided radial approach. Conversion to femoral approach was required in 2.6% of cases for the left internal carotid artery disease (n=7). Radial artery occlusion occurred in 3.7% of cases (n=10) and was asymptomatic in all cases. We present a video clip (https://youtu.be/3wZ6O8u-lpk) devoted to various surgical interventions through radial approach.
Conclusion:
Radial approach is safe and feasible and may be used for neuroendovascular procedures.
