Understanding Endarterectomy Surgery

Endarterectomy is a surgery that removes plaque from arteries to improve blood flow. It’s key for those with a lot of plaque buildup in their arteries. This buildup can cause heart problems.

Definition and Purpose

Endarterectomy is a surgery that removes plaque from artery walls. Its main goal is to improve blood flow. It also helps prevent strokes and reduces symptoms of blocked arteries.

Plaque Removal Process

To remove plaque, a surgeon makes an incision in the artery. They then carefully take out the plaque and close the artery. This must be done with great care to avoid harming the artery walls.

Benefits of the Procedure

Endarterectomy improves blood flow and lowers the risk of heart problems. It also relieves symptoms like pain or numbness in limbs. Successful endarterectomy can greatly improve a patient’s life.

Common Types of Endarterectomy Procedures

There are many types of endarterectomy procedures. Each targets different arteries.

Carotid Endarterectomy

Carotid endarterectomy removes plaque from the carotid arteries. These arteries supply blood to the brain. This is vital for preventing strokes.

Femoral Endarterectomy

Femoral endarterectomy removes plaque from the femoral arteries in the legs. It helps improve leg circulation and reduces symptoms of peripheral artery disease.

Other Arterial Sites

Endarterectomy can also be done on other arteries. This includes the aortic, renal, or mesenteric arteries. It depends on where and how much plaque there is.

Type of Endarterectomy	Arterial Site	Purpose
Carotid Endarterectomy	Carotid Arteries	Prevent Stroke
Femoral Endarterectomy	Femoral Arteries	Improve Leg Circulation
Aortic Endarterectomy	Aorta	Restore Aortic Blood Flow
