Radial artery access with a sheathless 0.087" inner diameter balloon guide catheter (Walrus) for neurointerventional procedures: Technique and clinical outcomes.

The Walrus 0.087" ID BGC is an effective tool that can safely be used via the radial artery using a sheathless approach, which helps to maximize the size of the catheter that can be used. This is the first instance of our knowledge of this technique being utilized for neurointerventions and therefore could be used to expand the indications for TRA for a wider range of procedures.
