Endarterectomy is a surgery to remove build-up in blood vessels. It is most often done in:
Plaque is a build-up on the lining of blood vessels. It can cause the artery to narrow and harden. This build-up and damage to the blood vessel is known as atherosclerosis. The plaque can slow and even stop blood flow. It can lead to stroke, weakness, cramps, and aching.
Endarterectomy is done to remove the build-up. It should improve blood flow. The symptoms should also improve.

Your doctor will talk about things that increase the risk of problems such as:
Your risk of problems may also be higher if there is plaque build-up in other areas.
An exam will be done to make sure you are healthy enough for surgery. Images of the arteries will be reviewed.
Let the doctor know about any medicine you are taking. Some medicine may need to be stopped up to 1 week before the procedure.
Anesthesia will be based on where the artery is. Options include:
Incisions will be made over the artery. Blood flow can be stopped to some areas until the work is done. Blood flow through the neck cannot be stopped. A new pathway will be made to allow blood flow while the artery is cleared out. A small tube or a piece of a vein may be used to create the new path.
A tube will be inserted into the artery. A sharp blade will trim the plaque away from the wall. A device can also help to catch and pull out loose plaque. The artery and skin will then be closed with sutures or staples.
The length will depend on the amount of plaque and place. It often takes several hours.
There will be some pain at the incisions. Medicine can help to ease pain.
You may be able to leave the same day or need to stay 1 day to 1 week. The stay may be longer if problems happen.
Care after the procedure may include:
Hospital staff will take steps to lower the risk of infection such as:
