Radial artery occlusion (RAO)may occur posttransradial intervention and limits the radial artery as a future access site. In this study, we investigate the incidence and factors influencing the RAO in the current literature.
A total of 66 studies with 31 345 participants were included in the analysis. Incident RAO ranged between 1 week follow-up).
The most efficacious measure in reducing RAO was higher dose of heparin, shorter compression times also reduced RAO. Several factors were found to be associated with RAO including age, sex, sheath size, and diameter of radial artery, but these factors were not consistent across all studies.
