radial artery spasm
Involuntary constriction of the radial artery during transradial catheterization, causing procedural difficulty and patient discomfort.
Full Definition
Radial artery spasm is a common complication of transradial cardiac catheterization characterized by involuntary arterial constriction that can impede catheter manipulation and cause patient pain. Spasm may be triggered by mechanical irritation, inadequate sedation, or vasoconstrictive medications. Prevention strategies include adequate local anesthesia, antispasmodic cocktails containing verapamil and nitroglycerin, and gentle catheter manipulation. Severe spasm may necessitate procedure termination or crossover to femoral access.
Usage
Usage note: Use complete term for clarity; 'radial spasm' alone may be ambiguous.
