Association Between Radial Artery Access Point and Radial Artery Spasm During Transradial Procedures

Radial artery puncture performed 0-20 mm proximal to the radial styloid process during transradial coronary angiography to evaluate its impact on the incidence of radial artery spasm (RAS).

Radial artery puncture performed at a distance greater than 21 mm proximal to the radial styloid process during transradial coronary angiography to evaluate its impact on the incidence of radial artery spasm (RAS).
