Systematic review and cost-benefit analysis of radial artery access for coronary angiography and intervention.

Radial artery access for coronary angiography and interventions has been promoted for reducing hemostasis time and vascular complications compared with femoral access, yet it can take longer to perform and is not always successful, leading to concerns about its cost. We report a cost-benefit analysis of radial catheterization based on results from a systematic review of published randomized controlled trials.
