Smaller radial arteries may heighten severe spasm risk after transradial access; leaves open whether diameter screening improves outcomes in repeat procedures.
Does the transradial approach for coronary angiography or angioplasty cause radial artery vasospasms in patients requiring repetitive procedures?
The transradial approach frequently induces asymptomatic radial artery vasospasms, which are strongly correlated with smaller baseline artery diameters but typically resolve spontaneously by 5 months.
Fukuda et al. (2004) studied this question.
