Zusammenfassung: | The efficacy of using composite arterial Y-grafts in off-pump coronary artery bypass has not been established. We assessed graft patency, long-term clinical outcomes, and the indications for composite arterial Y-grafting by reviewing 53 patients who underwent primary isolated elective off-pump coronary artery bypass with composite arterial Y-grafts between January 2002 and December 2008. Coronary angiography or 64-slice multidetector computed tomographic coronary angiography was used to assess graft patency. Follow-up raged from 18 to 97 months. The rates of mortality, graft failure, and recurrence of ischemic heart disease were 0%, 22.6%, and 13.2%, respectively. Only 4 (7.5%) patients required additional procedures (percutaneous coronary interventions or repeat surgery) because of graft failure. A significantly higher rate of graft failure was evident when one end of the composite graft was anastomosed to a 75% stenosed branch of a native coronary artery and the other end to a branch with >90% stenosis. The long-term patency of composite arterial Y-grafts in off-pump coronary artery bypass requires proper judgment of the indications. |
