Summary

Sequential coronary artery bypass grafting (CABG) using arterial conduits shows high patency rates and reliability for multiple vessel grafting. Distal anastomoses occlusion was noted, suggesting careful conduit selection is crucial.

Area of Science:

  • Cardiovascular Surgery
  • Vascular Grafting
  • Arterial Conduits

Context:

  • Coronary artery bypass grafting (CABG) is a common surgical procedure.
  • Arterial conduits offer advantages over venous grafts.
  • Sequential and skip bypass techniques are utilized to maximize graft utilization.

Purpose:

  • To evaluate the efficacy and outcomes of sequential and skip coronary artery bypass grafting using in situ arterial conduits.
  • To assess graft patency rates and reoperation requirements in patients undergoing these procedures.

Summary:

  • Forty-one patients received sequential or skip CABG using left internal thoracic artery (LITA) or right gastroepiploic artery.
  • No hospital deaths occurred; one late death from myocardial infarction in a skip bypass patient.

  • Overall graft patency was 95% (77/81), with three reoperations, all LITA sequential grafts.
  • Distal anastomoses occluded in 7 of 9 sequential grafts, while proximal anastomoses remained patent.

    • Impact:

    • Sequential arterial grafting is a viable and reliable option for complex coronary artery bypass grafting.
    • Graft caliber is critical; smaller conduits may be better suited for individual grafts rather than sequential configurations.
    • Findings highlight the importance of distal anastomosis patency in sequential arterial grafting strategies.
