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

## TL;DR

This paper describes a successful surgical approach to treat radial artery occlusion and vertebral artery stenosis using distal radial access.

## Contribution

The novel approach combines distal radial artery access with recanalization and stent placement for complex vascular conditions.

## Key findings

- Distal radial artery access enabled successful recanalization of a proximal radial artery occlusion.
- Stent placement in the vertebral artery was achieved without complications.
- The method offers a viable solution for patients preferring radial access despite prior occlusion.

## Abstract

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.
