Technical guide

Complications

  • 5% risk of radial artery occlusion which is clinically insignificant if the Allen test is normal.
  • Radial artery spasm, can be avoided by the use of local vasodilators.
  • Perforation of the radial artery is very rare, managed with compression. Rarely does it require vascular surgery intervention.
