Does coronary endarterectomy increase the risk of coronary bypass?
GROUND: With increased incidence of angioplasty and stent implantation, patients referred for coronary bypass (CABG) typically have more advanced and diffuse coronary disease. Thus, more patients may require endarterectomy in order to achieve complete revascularization. We compared our results in patients undergoing CABG with or without coronary endarterectomy. METHODS: Between 1993 and 1999, 2372 patients underwent isolated CABG in our department. A retrospective analysis was performed to compare patients requiring coronary endarterectomy of the LAD (group 1, n = 88), endarterectomy of arteries other than the LAD (group 2, n = 143), to those not requiring endarterectomy (group 3, n = 2071). Patients undergoing CABG without the use of cardiopulmonary bypass were excluded. Group 1 had a higher incidence of proximal LAD stenosis (p = 0.001) than group 3, while group 2 had a higher incidence of peripheral vascular disease (p = 0.02), preoperative MI (p = 0.03) and LV dysfunction (p = 0.00
