DISCUSSION
Complete revascularization of coronary vessels is the main target of CABG and in particular the LIMA-
LAD anastomosis, since a patent LIMA-LAD is the single most important determinant of the long-term and
[4]
event-free survival .
With advances in PCI, patients now referred to CABG are becoming more complex with multiple
comorbidities as well as less attractive target vessels. Diffuse coronary artery disease is a problem that faces
surgeons now with increasing frequency since in this subset of patients PCI produces less than optimal
[5]
results . In up to 25% of patients with diffuse coronary disease conventional CABG as well would not
[6]
optimally revascularize the ischemic territories . Therefore endarterectomy was revisited as an option to
increase the surgical armamentarium in facing this complex lesion.
