Summary

Sequential arterial grafting using the right gastroepiploic artery (RGEA) is effective for multiple coronary artery bypass grafting. This technique achieved a high patency rate and improved patient outcomes, demonstrating its clinical utility.

Area of Science:

  • Cardiovascular Surgery
  • Vascular Grafting
  • Coronary Artery Disease

Background:

  • Coronary artery bypass grafting (CABG) is a standard treatment for severe coronary artery disease.
  • Arterial grafts, such as the right gastroepiploic artery (RGEA), offer long-term patency compared to venous grafts.
  • Sequential grafting techniques aim to maximize the use of available arterial conduits.

Purpose of the Study:

  • To evaluate the efficacy and safety of sequential coronary artery bypass grafting using the right gastroepiploic artery (RGEA).
  • To assess the patency rates and clinical outcomes of RGEA sequential grafts in patients requiring multiple arterial bypasses.

Main Methods:

  • A retrospective review of 17 patients who underwent sequential RGEA grafting between January 1989 and March 1993.

  • Detailed description of various sequential anastomoses performed, including RGEA to target coronary arteries.
  • Postoperative angiographic assessment of graft patency in 16 patients.

    • Main Results:

    • A total of 33 anastomoses were performed across the 17 patients.
    • The overall graft patency rate was high at 93.9% (31 out of 33 anastomoses).
    • No early mortality was observed, and all patients remained angina-free postoperatively.

    Conclusions:

    • Sequential RGEA grafting is a feasible and effective technique for achieving multiple arterial bypasses in coronary artery surgery.
    • The high patency rate and excellent clinical results support the use of sequential RGEA grafting for complex CABG.
    • RGEA serves as a valuable arterial conduit for in situ sequential bypass grafting, enhancing treatment options for coronary artery disease.
