Editorial CommentRadial 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.

Randomized Controlled Trial Multicenter StudyA novel approach to reduce radial artery occlusion after transradial catheterization: postprocedural/prehemostasis intra-arterial nitroglycerin.
To evaluate whether administration of nitroglycerin through the sheath at the end of a transradial procedure might preserve the patency of the radial artery. ⋯ The administration of nitroglycerin at the end of a transradial catheterization, reduced the incidence of RAO, examined 1 day after the radial procedure by ultrasound. Postprocedural/prehemostasis pharmacologic regimens may represent a novel target for further investigation to reduce RAO.
