The radial artery (RA) can be safely used as a preferred graft for myocardial revascularization, alongside the internal thoracic artery. This study shows routine arterial grafting with RAs is effective and feasible in many patients.

Area of Science:

  • Cardiovascular Surgery
  • Vascular Grafting
  • Myocardial Revascularization

Background:

  • The radial artery (RA) is typically an alternative conduit for myocardial revascularization.
  • Large-scale routine use of the RA as a primary graft has not been documented.

Purpose of the Study:

  • To evaluate the safety and efficacy of routine use of the radial artery as a preferred graft in myocardial revascularization.
  • To assess the feasibility of achieving total or near-total arterial grafting using the RA.

Main Methods:

  • Prospective evaluation of radial artery harvest in 933 patients.
  • Subsequent use of the radial artery as a preferred coronary artery bypass graft in 930 patients.
  • Data collection on graft numbers, operative mortality, and limb function.

Main Results:

  • 1080 radial arteries were harvested, with a mean of 1.43 RA grafts per patient.
  • Operative mortality was 2.3%, with no deaths attributed to the RA graft.
  • No ischemia or motor dysfunction was observed in operated hands; 3.4% experienced transient dysesthesia.

Conclusions:

  • Routine total or near-total arterial myocardial revascularization is safe and effective using the radial artery.
  • The radial artery can be used routinely as a preferred graft alongside the internal thoracic artery.
  • This approach facilitates comprehensive arterial grafting in coronary artery bypass surgery.
