Administration of Rotaglide™ solution for treating refractory severe radial artery spasm: A case report.

Severe radial artery spasm is a complication of transradial cardiac catheterization. We describe a case of severe radial artery spasm causing catheter entrapment. The spasm was refractory and resistant to intra-arterial vasodilators, systemic vasodilators, and moderate sedation. Rotaglide™ (Boston Scientific, Marlborough, MA) solution via continuous infusion was delivered through the catheter and then the sheath, resolving the spasm and allowing the removal of the catheter and sheath without injury to the radial artery.
