Radial artery occlusion: Preventing Insult to Injury

Intra‐arterial nitroglycerin prior to transradial sheath removal may reduce the incidence of radial artery occlusion (RAO). Operators must observe careful attention to all aspects of transradial catheterization, particularly patent hemostasis; as well as independently monitor the institutional incidence of RAO to prompt improvements in practice. Future studies on the impact of pre‐puncture ultrasound, novel sheaths, hemostatic devices, and potent oral and intravenous antithrombotic therapy on 30‐day RAO diagnosed by ultrasound may allow further reduction of RAO in a real‐world practice.
