Abstract

Aim of the study. To estimate the immediate and medium-term results of revascularization of the right coronary artery (RCA) using composite T-grafts, venous bypasses, combined I-grafts.

Methods.It was a retrospective study included 223 patients who underwent revascularization of RCA using composite T-grafts, combined I-grafts (venous graft from the proximal part of right mammary artery) and venous bypasses from ascending aorta. Three groups were isolated based on the sign of the method of revascularization of RCA. Numbers of groups: 65 patients in the T-graft group, 112 in the group of venous bypasses, 46 in the I-graft group. There was no difference between the groups for the main preoperative data. Estimated blood flow bypass using intraoperative fluorometry. In a long term, all patients underwent coronary bypass angiography, a period of 16 to 43 months.

Results. Therewere no operative mortality and no new postoperative infarct.In the long-term period, 59 (90%) of the bypasses was a patency in group 1 (T-graft), 99 (88.4%) venous bypasses in group 2 and 42 (95.5%) of the I-grafts was patency.

Conclusions. For RCA bypasses the combined I-graft demonstrated the best patency in the long-term compared with T-graft and venous.
