Carotid endarterectomy
Carotid Endarterectomy[edit | edit source]
Carotid endarterectomy is a surgical procedure employed to remove atherosclerotic plaque or fatty deposits from the carotid arteries, which are vital vessels located on either side of the neck supplying blood to the brain. This procedure is essential for the prevention of stroke in patients with significant carotid artery stenosis.
Overview[edit | edit source]
The carotid arteries play a critical role in delivering oxygenated blood to the anterior part of the brain. Over time, fatty deposits or plaques can build up inside these arteries, reducing blood flow and posing a risk of stroke due to emboli or reduced blood supply.
Indications[edit | edit source]
Carotid endarterectomy is typically recommended for patients who:
- Have experienced symptoms of a transient ischemic attack (TIA) or mild stroke.
- Have significant narrowing (usually more than 70%) of the carotid artery detected via angiography or ultrasound.
- Are deemed at high risk for a stroke based on other medical factors.
Procedure[edit | edit source]
During the surgery:
- An incision is made along the front of the neck.
- The surgeon exposes the affected carotid artery.
- The artery is temporarily clamped to halt blood flow.
- The surgeon makes an incision in the artery and removes the fatty plaque.
- Blood flow is restored by closing the artery with sutures or a graft.
Post-Operative Care[edit | edit source]
After the procedure, patients are monitored for potential complications, including:
- Hematoma or excessive bleeding.
- Stroke or TIA symptoms.
- Potential nerve damage affecting speech or facial movement.
Risks and Complications[edit | edit source]
As with any surgical procedure, carotid endarterectomy carries certain risks:
- Stroke or TIA.
- Heart attack.
- Hematoma or bleeding at the incision site.
- Nerve injury affecting the voice box, tongue, or other areas.
Benefits[edit | edit source]
A successful carotid endarterectomy can significantly reduce the risk of stroke in patients with critical carotid artery stenosis. Early detection and intervention are crucial to maximize the procedure's benefits.
