Information provided by (Responsible Party):
VA Office of Research and Development
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.

Condition Intervention
Cardiovascular Disease Coronary Artery Disease Procedure: saphenous vein graft Procedure: radial artery graft

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single (Outcomes Assessor)
Primary Purpose: Treatment
Official Title: CSP #474 - Radial Artery vs. Saphenous Vein Grafts in Coronary Artery Bypass Surgery (Radial Artery)

Primary Outcome Measures:
  • To Compare 1-year Angiographic Patency of Radial Artery Grafts Versus Saphenous Vein Grafts in Patients Undergoing Elective Coronary Artery Bypass Graft (CABG) Surgery. [ Time Frame: 1 year ]
    The primary end point was angiographic graft patency at 1 year after coronary artery bypass surgery, defined as any opacification of distal target by injection of the graft. The window for the 1-year angiogram was 2 to 24 months. This window was chosen to capture early clinically indicated angiograms and late selective angiograms in patients who did not have symptoms. Study grafts that were occluded at 1 week after coronary artery bypass graft surgery were considered occluded at 1 year. One-year graft patency data were missing if patients whose study grafts were patent at 1 week did not undergo an angiogram within the time window or if the central angiography laboratory was not able to determine graft patency.

Secondary Outcome Measures:
  • Death [ Time Frame: Within 1 year of surgery. ]
  • Myocardial Infarction [ Time Frame: Within 1 year of bypass surgery ]
  • Stroke [ Time Frame: Within 1 year of bypass surgery ]

Ages Eligible for Study:   Child, Adult, Senior
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

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)
