Best Doctor List Near You for Endarterectomy in Nanaimo

Endarterectomy is a surgical procedure performed to remove plaque buildup from the inner lining of an artery, which can cause narrowing or blockage and restrict blood flow. This procedure is most commonly done on the carotid arteries, the major arteries in the neck that supply blood to the brain, to prevent stroke. It can also be performed on other arteries, such as the femoral or coronary arteries, when significant atherosclerosis (hardening of the arteries due to plaque) is present and poses a risk of heart attack or other complications. The surgery involves making an incision at the site of the blocked artery, opening the artery, and removing the plaque, which is composed of fat, cholesterol, calcium, and other substances. Once the plaque is removed, the artery is stitched closed, and sometimes a patch is placed to widen the artery and improve blood flow. This restores normal circulation and reduces the risk of stroke or other ischemic events. Complications of endarterectomy can include infection, bleeding, and damage to the artery, which may lead to re-narrowing (restenosis) or clot formation. In the case of carotid endarterectomy, there is also a risk of stroke during or after the procedure if a blood clot or piece of plaque breaks free and travels to the brain. Nerve injury, leading to changes in voice or difficulty swallowing, is another potential complication. Despite these risks, endarterectomy is an effective treatment for reducing the risk of stroke and improving blood flow in patients with significant arterial blockages.
