Managing Persistent Radial Artery Spasm During Coronary Catheterization: A Complex Case Study.

This case report details the management of persistent radial artery spasm during coronary catheterization, unresponsive to standard pharmacotherapy. After conventional methods failed, deep sedation, neuromuscular blockade, and orotracheal intubation proved essential. We propose a structured step-wise approach to radial artery spasm, emphasizing adaptable strategies for treatment-resistant cases.
