Background:
The radial artery is used for the access of coronary angiography and percutaneous coronary intervention, as well as for coronary artery bypass surgery. Variations of upper limb arteries are common, however, congenital absence of radial artery is scarce, and most cases were unilateral radial artery absence.
Case Presentation:
During a coronary angiography of a 43-year-old man, we encountered a very rare bilateral congenital absence of the radial artery. For both arms, the radial arteries were not observed and the ulnar arteries were small in size, while anterior interosseous arteries were found to be the dominant artery. Coronary angiography and percutaneous coronary intervention were performed via the brachial artery since transradial percutaneous coronary intervention failed.
Conclusion:
The highlight of this case is that it could be the first case to be reported with bilateral absence of radial artery in adults.

01:11Assessment 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:

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.
