When used as an aorta-coronary bypass graft, the left internal thoracic artery (LITA) might remain open, despite significant restriction of flow through the graft. Potentially, a patent but nonfunctioning LITA might be reharvested and reused for repeat coronary artery bypass surgery (so-called LITA recycling). We report on our experience with successful reimplantation of the LITA during redo bypass surgery in 12 patients.
Patients and methods
Between 1997 and 2003, the LITA was reharvested and reinserted in 12 patients undergoing repeat coronary artery bypass grafting. There were 3 women and 9 men. The mean ± SD age of the patients was 64 ± 7 years (range, 5374 years). Written informed consent was obtained from all patients. The patients mean left ventricular ejection fraction was 38% ± 16% (range, 25%-60%). The patent but nonfunctioning LITA was reused only if preoperative coronary angiography showed that the diameter of the LITA lumen was normal or almost normal.
