Radial Artery Occlusion Recanalization via the Distal Radial Approach Followed by Vertebral Artery Stent Placement

Transradial access is increasingly utilized in neurointerventional procedures; however, due to the narrow diameter of the radial artery, puncture may induce radial artery spasm, and postoperative radial artery occlusion is a relatively common complication following transradial access. Although often asymptomatic, it poses challenges for subsequent radial artery access. In this instance, the patient experienced proximal radial artery occlusion subsequent to radial artery angiography, coupled with severe stenosis at the origin of the right vertebral artery. The patient strongly preferred radial artery access. Proximal radial artery puncture proved unsuccessful, so after puncturing the distal right radial artery, recanalization of the proximal radial artery was conducted, followed by stent placement in the right vertebral artery. The surgery was successful, and no complications arose postoperatively, offering a reference for future studies on proximal radial artery occlusion, distal radial artery access, and neurointerventional treatment.
