Carotid endarterectomy is a surgical procedure to remove the obstruction or disability in this artery. Carotid arteries are the two main blood vessels that line the head and neck.
Carotid endothelium is removed when a carotid artery is narrowed or both, due to accumulation of fatty deposits (plaque). This is known as carotid artery disease or carotid artery stenosis.
If the narrow carotid artery is left untreated, the blood flow to the brain may be affected by the formation of a blood clot and the thrombosis of it, which may lead to:
- Stroke ; a serious medical condition that can lead to brain damage or death.
- The transient ischemic attack (TIA) is called a mini-stroke, which is similar to stroke, but its signs and symptoms are temporary and disappear within 24 hours.
Carotid artery resection can significantly reduce the risk of stroke in people with severe carotid artery narrowing. The risk of another stroke or transient ischemic stroke, in those who have already had it, decreases by a third after surgery within the next three years.
Today, it is believed that the procedure should take place as soon as possible after the onset of symptoms. Therefore, immediate medical advice should be sought if the following symptoms occur:
- Numbness or weakness in the face , upper or lower extremity.
- Speech problems.
- Loss of vision in one eye.
Carotid endothelial resection
Carotid endothelium can be removed under local or general anesthesia. What distinguishes local anesthesia is that it allows the surgeon to monitor the brain function and the patient is yelled. However, there is no evidence that it is safer or better.
During this procedure, a 7-10 cm wound is performed between the jaw angle and the chest cavity (suture), then a small wound is performed along the narrow section of the artery, and the accumulated fatty deposits are removed.
After that, the artery closes with stitches or a stitch, and the wound is also closed with stitches.
What Happens After Carotid Carotid Resection?
The patient is transferred to the recovery section next to the control room. Most patients can leave home within 48 hours of surgery.
In most cases, the problems that a patient may suffer after surgery are limited to temporary numbness or discomfort in the neck .
However, there is a slight risk of more serious complications, which may include stroke or death in about 3 per cent of cases. However, this is less likely in people with carotid artery disease if they do not choose to undergo the procedure.
Are there alternatives to surgery?
Carotid artery stent placement is an alternative procedure called carotid artery stent placement, which can sometimes be used.
This procedure is simpler than its predecessor, because it does not involve causing injury to the neck, but being the introduction of a flexible and thin tube in the carotid artery through a small incision in the groin area (the pain Bgenah or groin), and then a network cylindrical placed (template or enacted) in The narrow area of the artery to expand, allowing the blood to flow through it more easily.
Carotid stenting is thought to be associated with an increased risk of stroke during this procedure, especially when done in the first few days of symptoms. But an alternative and useful procedure for people who may be at greater risk for complications after carotid artery resection surgery.
