Significance of Preoperative Evaluation of the Right Gastroepiploic Artery Graft to the Coronary Artery in Patients Undergoing Abdominal Surgery

Abstract

It is important to determine whether an RGEA graft is present when repeat laparotomy is required after CABG. In cases where an RGEA graft is present, it is essential to evaluate the patency and location of the graft since this will be crucial for planning the reoperation strategy. Preoperative recognition and evaluation of the RGEA graft can help avoid graft injury, even if the graft cannot be detected intraoperatively.

Simple transabdominal minimally invasive direct coronary artery bypass surgery with right gastroepiploic artery

“…Furthermore, indication should be screened carefully before operation, which is isolated RCA lesion with no gastric ulcer, tumor or other lesions in the stomach and no stenosis in the abdominal aorta and abdominal cavity. Finally, the patient will have a risk of injury to the RGEA when upper abdominal surgery, such as gastric and liver are required in the future 7 ; if surgery for the treatment of stomach cancer is conducted, the removal of infrapyloric lymph nodes will be affected 8 . When these surgeries are required by the patient, the cooperation plan should be formulated by cardiologist, surgeon, anesthesiologist, and operator together to ensure the safety of the patient.…”

Conduits Used in Coronary Artery Bypass Grafting: A Review of Morphological Studies

“…2,60) In 1984, Pym et al were the first to report its use for revascularization of the posterior marginal artery and RCA. 2,61,62) Due to the satisfactory results, this vessel is still considered an option for CABG. 62) The RGEA is considered the third option for CABG.…”

“…5) One concern is the potential damage of the graft or spasm during abdominal surgery. 62) The main mechanism of graft failure is a reduction in intraluminal diameter or occlusion when used for revascularized arteries with low-grade stenosis. 5) Results of morphological studies of RGEA are shown in Table 5.…”
