A new very-small-bore Simmons guiding sheath for transradial neurointervention: Technical note and initial experience

J Neuroradiol. 2024 Mar;51(2):214-219. doi: 10.1016/j.neurad.2023.08.004. Epub 2023 Aug 23.

Abstract

Transradial access during neurointerventions has increased in popularity because of reduced complications and patient preference. Nevertheless, transradial cannulation into the left common carotid artery can be difficult technically because of the lack of catheter support in the aortic arch. Furthermore, the use of large sheaths can increase the risk of complications at the access site. Here, we developed a new very-small-bore transradial system using a 3F Simmons guiding sheath, to increase the procedural success rate and minimize access-site complications. This system can represent a valuable treatment option for neurointerventions and has the potential to expand the indications for transradial access.
