Coronary artery bypass surgery utilizing right gastroepiploic artery

Area of Science:

• Cardiovascular Surgery
• Vascular Grafting

Background:

• Coronary artery bypass grafting (CABG) is a standard treatment for coronary artery disease.
• Graft selection is crucial for long-term patency and patient outcomes.
• Alternative graft materials are explored for challenging cases and reoperations.

Purpose of the Study:

• To evaluate the utility of the right gastroepiploic artery (R't GEAR) as a graft in coronary artery bypass surgery.
• To assess R't GEAR's efficacy when left internal mammary artery (LIMA) or saphenous vein (SV) utilization is compromised or insufficient.
• To determine the suitability of R't GEAR in total or near-total arterial revascularization strategies.

Main Methods:

• A retrospective study of 15 patients undergoing CABG using R't GEAR in combination with LIMA or SV.
• Analysis of reasons for R't GEAR utilization, including previous surgery, LIMA compromise, and arterial revascularization goals.
• Documentation of coronary arteries revascularized by R't GEAR, LIMA, and SV.

Main Results:

• No hospital mortalities were observed in the 15 patients.
• A total of 40 coronary arteries were successfully revascularized using the studied grafts.
• Satisfactory early results were reported in follow-up studies.

Conclusions:

• The right gastroepiploic artery (R't GEAR) is a viable graft option for coronary artery bypass surgery.
• R't GEAR is particularly valuable in reoperations and when LIMA harvest is difficult or vein grafts are limited.
• This preliminary experience suggests R't GEAR can be a graft material of choice in specific challenging CABG scenarios.
