Introduction
Coronary artery bypass grafting (CABG) in patients with end-stage renal
disease is often challenging due to graft selection, comorbidities, and
complex perioperative management. Internal thoracic artery (ITA)
grafting shows a survival benefit over saphenous vein grafting in
non-dialysis1-5 and dialysis
patients6. ITA grafts could be favorable for all CABG
patients, because these grafts show less arteriosclerotic changes than
other grafts3,5. In addition, bilateral internal
thoracic artery (BITA) grafting improves long-term survival compared
with single internal thoracic artery (SITA)
grafting7-13. However, one recent trial showed no
significant difference 14. Moreover, the efficacy of
BITA grafting in dialysis patients remains unclear15.
We compared the short- and long-term results of BITA grafting and SITA
grafting, and clarified the benefits of BITA grafting in patients with
dialysis-dependent end-stage renal disease.
