A stroke occurs when blood flow to the brain is cut off. This can be caused by a blockage in the carotid arteries, which are the main blood vessels that carry oxygen and blood to the brain. Carotid endarterectomy is a surgical procedure that can be performed to open a blocked carotid artery and prevent another stroke. The timing of carotid endarterectomy is important, as performing the procedure too early or too late can increase the risk of complications such as late stroke. It is recommended that carotid endarterectomy is performed within 14 days of the onset of symptoms, with the ideal timing being between 3 and 7 days from the index event.

Carotid endarterectomy is a surgical procedure to remove plaque buildup in the carotid arteries
During the procedure, the surgeon makes an incision in the neck at the site of the blockage and may use a tiny tube to temporarily reroute blood flow. An incision is then made along the portion of the artery containing the plaque, and the plaque is removed. The opening is stitched closed, often with a patch of material to widen the artery and prevent future narrowing. Finally, normal blood flow to the brain is restored.
The timing of carotid endarterectomy is crucial. For patients with symptomatic carotid occlusion, the procedure should be performed as soon as possible, ideally within two weeks of symptom onset, to effectively reduce the risk of stroke. Delays beyond two weeks can significantly increase the number of people needed to treat to prevent a single stroke. Very early surgery, within 48 hours of symptom onset, has been associated with an increased risk of late stroke occurrence.
Carotid endarterectomy is generally recommended for patients with carotid artery disease who have experienced a TIA or mild stroke, or who have severe narrowing or blockage (usually at least 80%) but have not had any symptoms. The procedure can significantly reduce the risk of stroke and improve overall survival rates. However, it is important to note that there are also risks associated with the surgery, including future artery blockage, stroke, nerve injury, and other complications.
To determine if carotid endarterectomy is the appropriate treatment, a vascular surgeon will review the patient's medical history and perform diagnostic tests. The procedure is typically performed in a hospital surgical suite, and the patient may be given general or regional anesthesia. Recovery from the surgery is generally rapid, with most people being discharged from the hospital the day after the procedure. However, it is important for patients to adopt a healthier lifestyle after the surgery to prevent future plaque buildup.

The surgery takes around one to two hours
A carotid endarterectomy is a surgical procedure to remove plaque buildup in the carotid arteries. The surgery takes around one to two hours. Here's what happens during the procedure:
First, the patient is administered general or local anaesthesia. Under local anaesthesia, the patient will be sleepy but will not feel the area being operated on, and will be given a sedative and pain medication as needed. Under general anaesthesia, the patient will be asleep, and a breathing tube will be inserted into their throat and windpipe to provide air to their lungs.
Next, the vascular surgeon will make a small incision, typically around 4 inches long, in the patient's neck at the site of the blockage. They may use a tiny tube to temporarily reroute blood flow around the blockage or clamp off the blood flow. The surgeon then makes an incision along the portion of the artery containing the plaque, removes it, and stitches the opening closed. In some cases, they may need to patch the artery with a piece of fabric or tissue from the patient's vein to widen it and prevent narrowing from reoccurring.
After the plaque has been removed, the surgeon restores normal blood flow to the brain and closes the incision in the neck with sutures. A small tube (drain) may be placed in the neck to remove any blood or fluid that accumulates. The patient will likely spend one or two days in the hospital recovering, during which they may be given medication to control pain and prevent blood clotting.
Following the surgery, patients should expect a sore and bruised neck for several days, and many people experience difficulty swallowing. Soft foods are often recommended during the initial recovery period. Driving and other activities that require turning the head may also be challenging until the neck pain subsides.
It is important to note that carotid endarterectomy carries some risks, including stroke, heart attack, and nerve damage affecting the muscles in the mouth, throat, or face. However, with an experienced surgeon, these risks are minimal.

Recovery from the procedure is rapid, with most people going home the day after
Recovery from a carotid endarterectomy is usually rapid, and most people can go home the day after the procedure. Once home, it is essential to follow specific care instructions to ensure a smooth recovery.
- It is safe to shower, but avoid scrubbing the surgical glue or letting a direct stream of water hit it.
- Check your incision daily, and avoid applying any lotions or creams to it.
- Avoid wearing clothes that rub against the incision to prevent irritation.
- Refrain from driving, lifting heavy objects, or engaging in strenuous activities for the first week or two.
- Get ample rest, and avoid overexertion.
- Take any prescribed medications as directed.
- Follow a soft, bland diet if you experience swallowing difficulties.
- You may experience neck pain, a sore throat, and trouble swallowing for a few days to a few weeks after surgery. These symptoms typically resolve gradually.
- You can resume most normal activities within three to four weeks, but older patients or those with health conditions like diabetes or cardiovascular disease may require a longer recovery period.
- Follow-up appointments with your doctor are crucial for monitoring your healing, checking for complications, and removing stitches.
- To prevent plaque buildup, adopt lifestyle changes such as a healthier diet, regular exercise, and stress reduction.

There are risks associated with the surgery, including stroke and intracerebral haemorrhage
Carotid endarterectomy is a surgical procedure that can be performed after a stroke to prevent another one from occurring. It involves the removal of plaque (fat and cholesterol buildup) from inside the carotid artery, which supplies blood to the brain and face. However, there are risks associated with the surgery, including stroke and intracerebral haemorrhage.
The risk of stroke occurring as a result of the procedure is estimated to be between 2% and 7%. This risk is higher for those who have already had a stroke or mini-stroke, with rates of 5% to 7%, compared to 2% to 3% for those who have not. The timing of the surgery also plays a role, as performing the procedure within 48 hours of the initial stroke has been associated with an increased risk of late stroke.
Cerebral hyperperfusion syndrome (CHS) is another potential complication, with an incidence rate of around 1.7%. CHS can lead to seizures and intracerebral haemorrhage. A brief interval between ischemic symptoms and endarterectomy has been identified as the clearest risk factor for CHS.
In addition to the risk of stroke and intracerebral haemorrhage, other possible complications include nerve damage affecting the muscles in the mouth, throat, or face, as well as temporary numbness in the face or tongue due to nerve damage. These issues typically resolve within a month and often do not require treatment.
While carotid endarterectomy carries these risks, it is important to note that an experienced surgeon can minimise them. Additionally, the benefits of the procedure may outweigh the risks in certain situations, especially when performed within an optimal timeframe and for patients who have already suffered a stroke.

To prepare for the surgery, you may need to stop taking certain medications and adopt healthier lifestyle habits
Preparing for an endarterectomy procedure involves several steps to ensure the surgery is as safe and effective as possible. Here are some detailed instructions and considerations to prepare for the surgery, focusing on medication adjustments and adopting healthier lifestyle habits:
Medication Adjustments:
- It is crucial to inform your doctor about all the medications, herbal products, dietary supplements, and blood thinners (anticoagulants) you are currently taking. They will provide specific instructions on which medications to stop or adjust temporarily before the procedure.
- In some cases, your doctor may advise you to start taking medicines that inhibit platelets and clots, such as aspirin, for a period before the surgery.
- If you are diabetic, it is important to discuss any necessary adjustments to your medication on the day of the surgery.
Lifestyle Modifications:
- Diet: Adopt a healthier diet to lower your cholesterol levels and prevent future plaque buildup. This typically involves reducing your intake of fatty and cholesterol-rich foods.
- Smoking: Stop smoking and using tobacco products. Smoking increases your risk of plaque buildup and can negatively impact your recovery.
- Stress: Find ways to reduce your stress levels. High stress can contribute to plaque formation and increase your risk of cardiovascular complications.
- Exercise: Start an exercise regimen if it is safe for you to do so. Physical activity can help improve your overall health and reduce your risk of cardiovascular issues. However, be sure to avoid strenuous activity until your doctor advises it is safe.
It is important to follow your doctor's instructions and adopt healthier lifestyle habits to maximize the chances of a successful surgery and promote long-term cardiovascular health.
