Summary

Sequential gastroepiploic artery (GEA) grafting offers a viable option for complex coronary artery bypass grafting, demonstrating high patency rates and no early mortality in a small patient cohort.

Area of Science:

  • Cardiovascular Surgery
  • Vascular Grafting
  • Coronary Artery Disease

Context:

  • Coronary artery bypass grafting (CABG) is a standard treatment for severe coronary artery disease.
  • Graft selection is crucial for long-term outcomes.
  • The gastroepiploic artery (GEA) is an alternative autologous graft for CABG.

Purpose:

  • To evaluate the feasibility and early outcomes of sequential in situ gastroepiploic artery (GEA) grafting.
  • To assess the patency rate of sequential GEA grafts in patients requiring multiple coronary artery bypasses.

Summary:

  • Seven patients underwent sequential GEA grafting for coronary artery bypass.
  • Grafts were anastomosed sequentially to the right coronary artery and/or circumflex artery branches.
  • No early deaths occurred, and postoperative angiograms showed a 92.3% graft patency rate (12/13 anastomoses).

Impact:

  • Sequential GEA grafting provides an effective alternative when the internal thoracic artery is inaccessible.
  • This technique is indicated for patients needing multiple coronary artery bypass grafting.
  • High patency rates suggest GEA is a reliable option for complex revascularization.
