Radial artery access is often preferred in coronary interventions, but spasms can occur, causing pain and complications during the procedure.
In a study of 103 patients, the incidence of radial artery spasm was found to be 24.3%, with factors like female sex and failed puncture attempts increasing the risk, while hydrophilic sheaths seemed to prevent spasms.
Signs of arterial spasm were frequently observed in angiographies but did not always result in significant symptoms; tight narrowing at the sheath tip was a notable predictor of symptomatic spasm.
