Abstract
The purpose of this publication is to provide a comprehensive review on the techniques and tools used for vascular access in neurointerventional procedures. Using published literature, we reviewed data on access methods, sites, tools, and techniques for neurointerventions. Recommendations are provided based on quality of data/levels of evidence and, where appropriate, expert consensus. While tools and techniques continue to be developed, current literature and experience supports certain principles regarding vascular access for neurointerventional procedures.
