1/6: The superficial radial artery (SRA) is a rare anatomical variant with a 0.5% to 1% incidence rate.
2/6: When encountering a weak or absent radial pulse, check the lateral dorsal surface of the wrist for the SRA (Figure 1).
3/6: The SRA typically runs subcutaneously on the wrist radial border, crossing through the first intermetacarpal space (Figures 1).
4/6: It may be accompanied by a smaller regular radial artery terminating as the superficial palmar branch and/or a deep branch feeding the dorsal carpal arch.
5/6: The SRA is a viable, albeit infrequent, access option for percutaneous procedures = use US.
6/6: Among reports describing the SRA having been mistaken for the cephalic vein and its subsequent injection injury/thrombosis, which may require surgical intervention.
