Abstract:
Transradial access for percutaneous coronary intervention and diagnostic coronary angiography has been increasingly utilised in the routine practice in most catheterisation laboratories as it reduces the incidence of major access site complications such as bleeding and haematoma. Radial artery spasm with or without perforation is one of the more frequent reasons for converting from radial to femoral access. In this article, the balloon-assisted technique and Sheathless EauCath (Asahi Intecc, Aichi, Japan) are demonstrated to overcome radial artery spasm with associated significant perforation in two cases.

Assessment of radial pulse
The radial pulse, located at the wrist, is often the preferred site for assessing peripheral pulse because of its accessibility and dependability. The process of determining the radial pulse involves several steps:
Arteries of the Upper Limbs
Assessment of apical radial pulse
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.
