Radial Artery Versus Saphenous Vein Grafts in Coronary Artery Bypass Surgery

VA patients with coronary artery disease and who have agreed to undergo coronary artery bypass graft surgery would be randomized to receive either radial artery or saphenous vein to the study vessel. The primary outcome variable is graft patency at one year.

Stanford is currently not accepting patients for this trial.

Lead Sponsor:

US Department of Veterans Affairs

Stanford Investigator(s):


  • Procedure: saphenous vein graft
  • Procedure: radial artery graft




Inclusion Criteria:

   - Patients needing coronary artery bypass grafts.

Exclusion Criteria:

   - Patients who require only a single vessel bypass and in whom the internal mammary
   artery will be used for that graft

   - Patients with previous stripping and ligation of saphenous veins and in whom no venous
   conduit is available for bypass

   - Patients with Raynaud's symptoms

   - Patients who have a creatinine above 2.0 mg/dL or require hemodialysis

   - Patients with a positive Allen test

   - Patients with cardiogenic shock

   - Patients who are unable to give consent

   - Patients allergic to contrast material

   - Patients undergoing repeat CABG or any form of robotic surgery

   - Patients who do not have full use of both arms

   - Patients who are pregnant

   - Patients with neurologic or musculoskeletal disease affecting the arm

   - Patients who refuse to participate

   - Patient requires any concomitant valve operation in the mitral, aortic, or pulmonary
   position. Isolated tricuspid annuloplasty is acceptable, but tricuspid valve
   replacement excludes the patient from consideration.

   - Patient requires concomitant Dor or Maze procedure

   - Patient is in another research study

   - No suitable radial target (there is no non-LAD vessel with a >70% stenosis)
