Incidence and risk factors of radial artery spasm during distal radial angiography

Objective: Radial artery spasm (RAS) is a common complication of radial coronary angiography. Our aim was to assess how different risk factors influence the occurrence of RAS during distal radial coronary angiography. Patients and Methods: A total of 183 consecutive patients undergoing distal radial angiography at 2 centers were included in our study. RAS was defined clinically. The relationship between the demographic and clinical characteristics of the patients and the development of RAS was evaluated. Results: Radial artery spasm developed in 23 (12.5%) of the patients. While the female sex ratio was higher in those who developed RAS, the mean age was lower (p
