Transradial approach and its variations for neurointerventional procedures: Literature review

Background: The transfemoral approach (TFA) has been the standard in neuroradiology over the years. However, the transradial approach (TRA) and its variants offer several benefits over the TFA. Methods: Review of the literature about TRA and its variations. We present our results for different neurointerventional procedures at our institution between January 2018 and December 2019. Results: We wrote an educational review describing anatomical and technical aspects, advantages, and complications of this approach. In the past year we increased the percentage of neurointerventional procedures performed through radial or ulnar arteries. Conclusion: There are clearly proven benefits of employing a wrist approach in patients for neurointerventional procedures and its utilization should especially be considered on a daily basis.
