Overview

Potential Pitfalls of the Radial Approach to Cardiac Catheterization

  1. Spasm
  2. Vessel tortuosity
  3. Guide catheter support and selection may be reduced
  4. Loss of radial artery pulse in 4% of cases
  5. Potential increase in the duration of the procedure and fluroscopy time
  6. The radial artery has been instrumented should there be a desire to use it as a conduit for CABG
  7. It is the second and not the first approach learned by trainees
  8. There is a learning curve in treating spasm, navigating anatomy, and manipulating catheters
  9. Anatomically there can be a loop in the artery near the brachial in about 10% of cases
  10. Smaller sheaths are required (4-8F)
