Right gastroepiploic artery: an alternative arterial conduit for coronary artery bypass
1Department of Surgery, National Yang-Ming Medical College, Taiwan, R.O.C.
Insights
The right gastroepiploic artery (RGEA) is a viable arterial conduit for coronary artery bypass surgery. This study found RGEA grafts achieved 100% early patency, offering a valuable option for myocardial revascularization.
Area of Science:
- Cardiovascular Surgery
- Vascular Grafting
- Cardiac Procedures
Background:
- Coronary artery bypass grafting (CABG) is a critical procedure for myocardial revascularization.
- The search for optimal arterial conduits to improve CABG outcomes is ongoing.
- The right gastroepiploic artery (RGEA) has emerged as a potential alternative graft.
Purpose of the Study:
- To evaluate the early outcomes and graft patency of using the right gastroepiploic artery (RGEA) as an arterial conduit in myocardial revascularization.
- To assess the safety and efficacy of RGEA grafts in combination with other arterial or venous grafts.
Main Methods:
- A retrospective review of 15 patients undergoing myocardial revascularization between September 1990 and February 1991.
- The surgical procedure involved the use of the right gastroepiploic artery (RGEA) combined with other arterial or venous grafts.
- Data collected included patient demographics, operative times, graft details, and early postoperative outcomes.
Main Results:
- Fifteen male patients (mean age 61.2 years) underwent myocardial revascularization with RGEA and other grafts.
- The mean number of distal anastomoses was 3.6, with an average of 3.1 grafts per patient.
- Early graft patency for RGEA was 100% (6/6) within 3 postoperative months, with one mortality (6.7%) and the remaining 14 patients alive and angina-free.
Conclusions:
- The right gastroepiploic artery (RGEA) demonstrates excellent early patency and is a safe and effective arterial conduit for coronary artery bypass surgery.
- RGEA should be considered a valuable third arterial conduit option for myocardial revascularization.
- Further research into long-term outcomes of RGEA grafts is warranted.
Abstract:
From September 1990 to February 1991, 15 cases of myocardial revascularization with the right gastroepiploic artery (RGEA) combined with arterial or venous grafts were performed at VGH-Taipei. All were males, ranging in age from 49 to 64 years (mean age 61.2 +/- 4.6 years). The mean number of distal anastmoses including vein grafts was 3.6 +/- 0.7 and the mean number of graft was 3.1 +/- 0.3 per patient. The mean aortic clamp time was 123.6 +/- 24.0 minutes and the mean cardiopulmonary bypass time was 176 +/- 35 minutes. There was one mortality (6.7%). The other 14 patients are alive without angina. Studied within 3 postoperative months, graft early patency was 100% (6/6) in GEA graft. GEA graft should be a third available arterial conduit for coronary artery bypass.
