**3.2. Outcome**

The risk of endarterectomy patients are higher compared to CABG alone. In some reports, long term patency is inferior to CABG, but in experienced hands operative mortality of 3.0% and 5-year survival of 87% can be achieved. [19] The most significant complication is periooperative MI after endarterectomy. It is significant higher compared to CABG alone including MI occurrence which occurs in 5-10%. [20] Multiterritory endarterectomy is associated with worse long term survival (64% 5-year survival and 36% 10-year survival), but this could be due to higher risk patient population. [21]

LAD endarterectomy was intially reported with increased incidence of morbidity and mortality. [22 23] With technical modifications including LITA grafting with saphenous vein patch and LITA onlay patch grafting, the outcomes in this high risk group has significantly improved. [24] Endarterectomy provides good results and mainstay of the treatments for patients with severe diffuse coronary artery disease not amenable to PCI and traditional surgical intervention.
