Could radiation exposure be the Achilles’ heel of distal transradial artery access?

Distal transradial access for vascular interventions has gained ground recently. While the novel approach is associated with reduced radial artery occlusion and faster hemostasis, it could be related with prolonged procedural time, higher crossover rate and increased radiation, comparing to conventional transradial approach. Whether the radiation is increased in the procedures performed by the novel approach remains unambiguous. In the specific article, we aim to review the current literature and to propose possible explanations for this phenomenon. Could radiation be the Achilles’ heel of distal transradial artery access?
