Coronary endarterectomy, open, any method, of left anterior descending, circumflex, or right coronary artery performed in conjunction with coronary artery bypass graft procedure, each vessel (List separately in addition to primary procedure)

An open coronary endarterectomy is a surgical procedure aimed at removing atheromatous plaque from the coronary arteries, specifically the left anterior descending, circumflex, or right coronary artery. This procedure is performed using any method during a coronary artery bypass graft (CABG) operation, which is a separate and reportable procedure. The need for coronary endarterectomy typically arises in patients with diffuse atherosclerotic coronary artery disease, where the arteries are narrowed or blocked due to the buildup of fatty deposits. During the procedure, the surgeon explores the coronary artery using finger palpation to assess the extent of the disease. An incision is made in the arterial wall to access and remove the atheromatous core, which may involve extending the arteriotomy to inspect major branches and ensure thorough plaque removal. Various techniques can be employed for plaque extraction, including eversion-type endarterectomy or direct vision methods. After the plaque is removed, the arteriotomy is closed with sutures or a patch made from a saphenous vein. It is important to note that if multiple vessels are treated during the procedure, the coronary endarterectomy should be reported separately for each vessel involved.
