I-Composite Graft with Right Internal Thoracic Artery and Right Gastroepiploic Artery in Coronary Artery Bypass Grafting.
Purpose: When added to the internal thoracic artery (ITA), the right gastroepiploic artery (GEA) has been used as an in-situ graft or an I-composite right ITA-right GEA graft in coronary artery bypass grafting (CABG). We aimed to verify its potential.
Methods: We evaluated 104 patients who underwent first isolated CABG with this I-composite graft. The number of distal anastomoses, graft flow (GF) and pulsatility index (PI) during surgery, and graft patency in the early term regarding this I-composite graft were evaluated.
Results: The number of total distal anastomoses and distal anastomoses with arterial grafts were 4.17 ± 0.81 and 3.63 ± 0.81, respectively. This I-composite graft achieved 2.38 ± 0.69 distal anastomoses. GF tended to increase according to the increased number of distal anastomoses (p = 0.241), and the PI maintained a low score regardless of the number of distal anastomoses (p = 0.834). Graft patency was 95.5%; moreover, the number of distal anastomoses with this I-composite graft did not affect early-term graft patency.
Conclusion: Right GEA utility was expanded as this I-composite graft in addition to in-situ graft. This I-composite graft has an adequate flow capacity for revascularization in non-left anterior descending coronary artery lesions.
