Meta-Analysis Comparing Distal Radial Versus Traditional Radial Percutaneous Coronary Intervention or Angiography

Data comparing outcomes of distal radial (DR) and traditional radial (TR) access of coronary angiography and percutaneous coronary intervention (PCI) are limited. Online databases including Medline and Cochrane Central databases were explored to identify studies that compared DR and TR access for PCI. The primary outcome was the rate of radial artery occlusion (RAO) and access failure. Secondary outcomes included access site hematoma, access site bleeding, access site pain, radial artery spasm, radial artery dissection, and crossover. Unadjusted odds ratios (ORs) with a random-effect model, 95% confidence interval (CI), and p
