Carotid artery disease, characterized by plaque buildup in the carotid arteries, is a significant risk factor for stroke. Carotid endarterectomy (CEA) is a surgical procedure to remove this plaque and reduce the risk of stroke, especially in individuals with significant stenosis of the carotid arteries. This article provides a comprehensive guide to diet and recovery following carotid artery surgery, drawing upon a variety of medical sources and research findings.
Immediate Post-Operative Period
Hospital Stay:
Following a carotid endarterectomy, patients typically stay in the hospital overnight for monitoring. It's common to experience neck pain for about two weeks after surgery, which can be managed with over-the-counter pain medications.
Initial Diet:
Several hours after surgery, patients can usually resume eating and drinking. If general anesthesia was administered, starting with liquids or light foods is recommended, gradually progressing to a normal diet as tolerated. Unless instructed otherwise, patients can typically resume their regular diet.
Dietary Recommendations for Optimal Recovery
General Guidelines:
A balanced diet is crucial for recovery. A low-salt, low-fat, and easily digestible diet is generally recommended to maintain a balanced nutritional intake. This supports the body's healing processes and overall recovery.
Specific Dietary Components:
- Fruits and Vegetables: Emphasize plenty of fruits and vegetables in your diet. Fresh or frozen options are preferable to canned ones, which may contain added salt or sugar.
- Fiber-Rich Foods: Incorporate high-fiber foods like whole-grain breads, pastas, cereals, and crackers into your meals.
- Lean Proteins: Opt for lean meats and skinless chicken or turkey as protein sources.
- Fish: Consume fish at least twice a week due to its beneficial effects on arteries.
Foods to Limit or Avoid:
- Saturated Fats: Reduce saturated fat intake, as it can raise blood cholesterol levels.
- Cholesterol: Lower cholesterol intake to prevent further plaque buildup.
- Added Salt and Sugar: Minimize the consumption of added salt and sugar.
- Trans Fats: Avoid trans fats found in hydrogenated oils, baked goods, and certain processed foods.
Enhanced Recovery After Surgery (ERAS) Nutritional Support
ERAS Protocol:
An Enhanced Recovery After Surgery (ERAS) protocol aims to reduce complications and speed up patient recovery through various perioperative methods. This includes addressing both physical and psychological stress experienced by surgical patients.

Nutritional Intervention:
A multidisciplinary ERAS nutritional protocol includes several key aspects:
- Preoperative Management and Assessment: Correcting malnutrition, improving nutritional status, and optimizing body composition. For malnourished patients, enteral nutrition (EN) support, usually with oral nutrition supplementation, is preferred 7-10 days before surgery.
- Intraoperative Management: Selecting appropriate surgical positions and approaches, administering ropivacaine for local anesthesia, and combining general anesthesia with regional nerve block anesthesia.
- Postoperative Nutritional Support: Providing parenteral nutrition (PN) and EN support based on the patient's gastrointestinal condition. Liquid food can be introduced 6 hours after surgery, progressing to semi-liquid food once intestinal ventilation is restored.
Lifestyle Modifications to Prevent Plaque Buildup
Healthy Diet:
Adopting a heart-healthy, low-fat diet is essential. This includes plenty of vegetables, lean meats, fruits, and high-fiber grains.
Regular Exercise:
Engaging in regular physical activity, if deemed safe by a healthcare provider, is important. Aim for at least 150 minutes of moderate exercise per week. Walking is an accessible way to start.
Avoid Tobacco:
Smoking should be avoided, as it increases the risk of stroke.
Stress Reduction:
Managing stress levels is crucial for preventing plaque buildup.

Cholesterol Management:
Taking medicine to lower cholesterol levels, if prescribed, is essential for preventing plaque buildup.
Managing Risk Factors
Lowering Cholesterol:
Eating a diet low in fat and cholesterol is important.
Controlling Blood Sugar:
High blood sugar levels can damage the lining of carotid arteries, so managing blood sugar is vital.
Lowering Blood Pressure:
High blood pressure can cause wear and tear on blood vessels, increasing the risk of artery narrowing.
Detailed Post-Operative Instructions
Activity:
- Daily walks are helpful.
- Sitting with elevated legs is advised.
- Avoid sitting with legs down or standing for long periods during the first month.
Wound Care:
- Wash wounds daily with soap and water.
- Steri-strips should be removed by the end of the first week.
- Massage around the incision to restore sensation.
- Showering is permitted, but avoid scrubbing the surgical glue or letting water directly hit the incision.
Medications:
- Resume pre-operative medications as directed.
- Take prescribed pain medication as directed.
- Aspirin, clopidogrel, or other medicines to prevent blood clots may be prescribed.
What to Expect During Recovery
Physical Changes:
- Fatigue: Feeling tired or having low energy is common after surgery and usually improves after two weeks.
- Neck Pain: Neck pain is a common complication that may last for about two weeks.
- Numbness: Numbness near the jawline and earlobe may occur for six months to a year.
- Incision Care: Check the incision daily and avoid applying lotions. Wear loose clothing to prevent rubbing against the incision.
Returning to Normal Activities:
Most normal activities, including work, can be resumed in one to two weeks. Driving is permitted once the incision has healed and it’s comfortable to turn the head.

Follow-Up Appointments
Regular follow-up appointments are crucial to ensure the carotid artery doesn’t narrow again. These visits usually occur one month after surgery, then every six months for two years, and annually thereafter. Ultrasound is used to check for narrowing in both carotid arteries.
Potential Complications and How to Manage Them
Normal Post-Operative Changes After Vein Surgery:
- Swelling: Common near the bandage area and improves with leg elevation after bandage removal.
- Bruising: May appear along the treated vein, incision areas, or ankles, and improves gradually. Arnica cream may help.
- Numbness: Caused by irritation of nearby nerves. Massaging the area can help.
- Pain/Inflammation: Mild discomfort or redness may appear about one week after surgery. Stretching can help relieve symptoms.
- Vein Sensation: Feeling a cord-like structure where the vein was treated.
Warning Signs:
Know the warning signs of a stroke and seek immediate medical attention if they occur. Symptoms include blurred vision, confusion, loss of memory, loss of sensation, problems with speech and language, vision loss, and weakness in one part of the body.
The Broader Impact of Lifestyle Changes
Women's Health Initiative Dietary Modification Trial:
The Women's Health Initiative (WHI) Dietary Modification Trial, involving nearly 49,000 postmenopausal women, examined the effect of a low-fat dietary pattern on the risk of incident carotid artery disease. The trial found no significant differences in the rate of incident carotid artery disease between the intervention and comparison groups.
Key Findings from WHI:
- The dietary intervention did not significantly reduce the risk of carotid artery disease.
- There was a suggestion of an unfavorable effect among those with a baseline history of coronary heart disease or hypertension.
- Significant interactions were observed between dietary habits and the intervention, particularly with total energy, fruit and vegetable, and fiber intakes.
Implications:
These findings suggest that a general low-fat diet may not be sufficient to reduce the risk of carotid artery disease. A more comprehensive approach focusing on specific dietary components and individual risk factors may be necessary.
Essential Medicines
Antiplatelets:
These medicines make platelets in the blood less able to stick together and cause clots.
Cholesterol-Lowering Medicines:
Statins are a group of cholesterol-lowering medicines.
