Abstract
The radial artery (RA) access is currently the gold standard to perform cardiovascular interventions. One of the more common limitations is radial artery spasm which is an often complication interrupting the procedure. Common risk factors associated with spasm include female gender, periprocedural anxiety, multiple puncture attempts, distal radial access, diabetes, hypertension, and smoking. The mechanism of spasm is complex and includes calmodulin and rho-kinase pathways leading to the smooth muscle contraction. Proper hydration, anxiety management, and adequate local anesthesia should be applied to decrease the risk of spasms. Radial cocktail is often used to prevent spasm. Its composition differs between catheterization laboratories and the effect is attributed either to the verapamil or nitroglycerin, with contradictory results of different studies. Balbay maneuver is also an effective mean of prevention. Hydrophilic-coated devices can be used both to avoid spasms or reverse them. Radial angiography can be used to differentiate spasm from a tortuosity and choose proper method of management. Fasudil, a Rho-kinase inhibitor, has been reported as a pharmacological method to prevent spasm and reverse radial artery spasm.
