Carotid Endarterectomy - Symptoms, Risks, and Procedure

Introduction:

Carotid artery stenosis, also known as carotid artery disease, is the process of narrowing the arteries of the heart. The carotid arteries are two extremely robust blood vessels that always supply pure or oxygenated blood to the brain, which is responsible for critical thinking and speech, along with sensory and motor functions. The pulse of the carotid artery can be felt at the side of the neck and the jaw.

Carotid artery disease has the strong potential to lead to the blockage of the cardiovascular blood vessels or the arteries of the heart. This will, in turn, lead to a spike in the risk of heart stroke. The coronary or the carotid arteries may undergo atherosclerosis - the long process of the stiffening and hardening of the inner surface of the arteries, leading to a drastic decrease in blood flow to the brain, resulting in a life-threatening stroke.

Carotid endarterectomy is an invasive surgical approach for treating carotid artery disease. In this procedure, the carotid artery is slit open, cleaned, and stitched back. The prognosis of carotid endarterectomy is good with a positive outlook, provided the patient follows the instructions of the healthcare professional and the nutritionist religiously.

What Are the Risks Involved in Carotid Endarterectomy?

Risks are the norm for any invasive or noninvasive procedure related to the cardiovascular system. Below are the risks involved in carotid endarterectomy.

• Stroke.

• Heart attack.

• Infection.

• High blood pressure.

• Swelling.

• Pooling of blood.

• Seizures.

• The nervous system is malfunctioning, especially of the five sensory organs.

• Blockage of the carotid artery.

• Intracerebral hemorrhage (bleeding in the brain tissue).

• Bleeding at the site of the incision.

• Irregular heartbeat.

• Blocked airway path.

What Are the Indications for Carotid Endarterectomy?

The indications for carotid endarterectomy are as follows:

• Severe narrowing of the carotid arteries.

• Blockage in the carotid artery.

• Patients who are at increased risk of stroke.

• Patients who have experienced carotid artery stenosis.

What Are the Signs and Symptoms of Carotid Artery Disease?

An individual suffering from carotid artery disease may not show any particular signs or manifestations, and this is because of the build-up of heavy plaque within the walls of the arteries that take place after a long time. This is why it is said that carotid artery disease has no particular warning signs. Mentioned below are some of the signs and symptoms of carotid artery disease.

• Blurring vision.

• Generalized weakness.

• Tingling sensation all over the body.

• Impaired or vision loss.

• Dizziness.

• Confusion.

• Difficulty in speech.

• Severe attacks of headache.

• Dementia.

• Difficulty in swallowing.

• Numbness.

• Weakness of the limbs.

• Weakness of facial muscles.

• Difficulty in understanding speech.

• Loss of balance.

• Drooping one side of the face.

• The trouble with information in sentences.

• Paralysis of one side of the body.

• Bruit or whistling sound of the heart.

• Garbled speech.

• Palpitations.

• Slight pain in the neck or face.

• Tenderness in the ear, jaw, or forehead.

• Losing muscle strength over time.

What Happens During Carotid Endarterectomy?

Carotid endarterectomy is suggested in patients with carotid artery disease. The healthcare provider is the best person to finalize and give a green signal for carotid endarterectomy. If the professional feels a patient is not the right fit for carotid endarterectomy, carotid artery stent surgery and carotid angioplasty are the two alternatives. The steps that occur during carotid endarterectomy are mentioned below.

• The patient is requested to empty their bladder before the procedure.

• An intravenous line is placed in the arm.

• Several other catheters and monitors are placed to evaluate blood pressure and other vital signs and drain any excretory fluids.

• Local anesthesia is administered, and a sedative is given to the patient to stay relaxed and calm.

• General anesthesia is also an option, but it depends on the patient's and the professional's discussion.

• Antibiotics are administered beforehand to avoid any occurrence of infection.

• The surgical site is sterilized with the help of an antiseptic solution or alcohol swab.

• The site or surgery receives an incision that exposes the carotid artery that needs to be treated.

• A shunt is placed to divert blood from the surgical site, which is necessary to maintain constant blood flow to the brain.

• While the shunt performs its function, the carotid artery is slit, and the accumulated fat and other plaque deposits are cleaned.

• The shunt is then removed, and the carotid artery that has been treated is carefully closed.

• The incision at the surgery site receives the required number of stitches.

• A suction bulb is placed at the surgical site for a few hours to drain any excess fluid or pooling of blood.

• A sterile dressing is finally placed.

What Happens After Carotid Endarterectomy?

After the completion of the procedure, the patient is continually monitored for several days in the intensive care unit or the recovery room. The diet is given after consultation with the respective surgeon and nutritionist. Specific bathing instructions are provided to the patient. Packaged foods, foods high in saturated fats and sugar, cholesterol-rich foods, and oily foods must be avoided. A mix of fresh fruits and green leafy vegetables with multiple strains of pulses and grains are to be followed. The diet plan is handed over to the patient after discharge and must be followed strictly.

What Are the Alternatives to Carotid Endarterectomy?

The alternatives to carotid endarterectomy are as follows:

• Carotid artery stent placement (less invasive than carotid endarterectomy, and the stent is placed in the blocked artery).

• Carotid angioplasty and stenting (during this process, the healthcare provider will place a catheter with a balloon in the blocked artery to widen it, and after that stent is placed).

• Trans carotid artery revascularization (a minimally invasive procedure in which the healthcare provider uses technology to reverse the blood flow from the brain).

Conclusion

Carotid artery stenosis, also called carotid artery disease, has the potential to be a life-threatening disorder if it is not diagnosed at the right time and is not treated promptly. It may additionally lead to a stroke that will eventually lead to sudden death or even permanent disability. Due to these reasons, one must always be aware of all the signs and symptoms of stroke and the clinical manifestations and thus act accordingly. An immediate, exact, and accurate management plan for carotid artery disease may be lifesaving. Carotid endarterectomy, or CEA, is the go-to treatment for carotid artery disease.

Additionally, the result of surgical intervention and stent placement is excellent. Therefore, the patient can expect a positive outlook after carotid endarterectomy. The quality of the patient's life is good, provided they follow the diet plan suggested after the procedure and strictly follow other preventive measures.
