Objective: Internal thoracic artery (ITA) is the graft of choice in coronary artery bypass (CABG operations) due to its advantages in survival, ischemia recurrence and need for reintervention. In this study, we retrospectively analyzed our CABG reoperations with right ITA (RITA).

Materials and Methods: Only the patients who had RITA graft in coronary revascularizations were enrolled in this study (n=12). Eleven patients (91.6%) were female and one male (8.4%). The average age of the patients was 57.4±5.9 (ranged, 48-66). The average duration of first and second CABG was 5.1±1.4 years (ranged, 1-6). Eight patients were operated off-pump. The mean duration of postoperative follow up was 5.0±1.9 years (ranged, 1.2-7.3) (total of 59.6 patient/years).

Results: There was no in-hospital death. The average durations of intensive care and hospital stays were 1.3±0.5 days (ranged, 1-2) and 6.2±1.5 days (ranged, 5-9). The mean NYHA functional capacity of the patients in the follow-up was 1.3±0.5 (ranged, Class 1-2). The difference was statistically significant (p=0.045). There was only one long term mortality during the follow-up.

Conclusion: ITA grafts should be preferred in the era of increasing CABG reoperations. Considering that the left ITA is used frequently in the initial operations, RITA should be the first graft of choice in the reoperations. The use of this graft does not cause increased mortality or morbidity.
