What Is an Endarterectomy?

An endarterectomy is a surgical procedure to remove a buildup of plaque from inside an artery. Plaque is made up of cholesterol, fat, calcium, and other substances that can build up over time and narrow the artery. This can reduce blood flow to the organs and tissues that the artery supplies.

An endarterectomy is typically done on arteries in the neck (carotid arteries), the abdomen (aortic artery), or the legs (femoral arteries). The procedure involves making an incision in the artery, removing the plaque, and then closing the artery.

Endarterectomies are often done to treat peripheral artery disease (PAD), which is a narrowing of the arteries outside of the heart. PAD can cause symptoms such as pain, numbness, and weakness in the affected limb. Endarterectomies can also be done to prevent strokes in people who have carotid artery disease (CAD), which is a narrowing of the carotid arteries.

The success rate of an endarterectomy depends on the location of the artery and the severity of the plaque buildup. However, most people who have an endarterectomy experience significant improvements in their symptoms.

Some of the risks associated with an endarterectomy include bleeding, infection, and damage to the artery. However, these risks are relatively rare.
