Carotid endarterectomy is an established surgical treatment for carotid artery narrowing (stenosis). By directly removing fatty deposits (plaque) from an artery supplying blood to the brain, the procedure can help reduce the risk of stroke. Tampa General Hospital offers CEA and a full range of other vascular surgery services for patients throughout Brooksville, Spring Hill, Crystal River and surrounding communities. Surgical procedures are performed at TGH Brooksville, with vascular consultations, personalized treatment guidance and continued monitoring conveniently available throughout the region.
What Is Carotid Endarterectomy?
CEA is an open carotid artery surgery that removes plaque buildup from inside a narrowed artery. The carotid arteries are major blood vessels located on either side of the neck that deliver oxygenated blood to the brain. Over time, fatty deposits can accumulate along the inner walls of these arteries, a process known as atherosclerosis. As plaque builds up, it can narrow the arteries and restrict blood flow to the brain, resulting in carotid artery stenosis.
During carotid endarterectomy, the vascular surgeon will access the affected artery through an incision in the neck, carefully open the artery and remove the plaque responsible for the narrowing. The surgeon will then close the artery, allowing blood to flow through the treated area. Unlike carotid stenting procedures, which use a stent to hold the narrowed artery open, carotid endarterectomy physically removes the plaque from the narrowed blood vessel.
How Does Plaque Buildup Increase Stroke Risk?
Carotid artery stenosis develops when plaque accumulates in a carotid artery, causing the passageway for blood to become progressively narrower. In addition to restricting blood flow, plaque can become unstable. Pieces of plaque or blood clots can break away, travel toward the brain and block smaller arteries, potentially causing a transient ischemic attack (TIA) or stroke. Sometimes called a “mini-stroke,” a TIA occurs when blood flow to part of the brain is temporarily blocked, causing stroke-like symptoms that resolve without causing a lasting brain injury.
Carotid stenosis often causes no noticeable symptoms until blood flow to the brain is disrupted. If the condition leads to a transient ischemic attack or stroke, symptoms may include sudden weakness or numbness on one side of the body, vision changes and difficulty speaking or understanding speech. TIA symptoms typically resolve within a short period, but they can be an important warning sign of an increased stroke risk and require prompt medical attention.
How Does Carotid Endarterectomy Help Prevent Stroke?
The primary goal of carotid endarterectomy is to reduce stroke risk by addressing plaque buildup that can interfere with blood flow to the brain. By opening the carotid artery and directly removing the plaque, the surgeon can create a wider passageway for blood and eliminate a major potential source of plaque debris.
Carotid endarterectomy may be performed as a stroke prevention procedure for an appropriately selected patient who has significant carotid artery narrowing. It may also be recommended after a TIA or stroke if carotid artery disease is determined to be a contributing factor.
Although carotid plaque removal surgery can reduce future stroke risk, it does not eliminate the underlying tendency to develop vascular disease. Medication, ongoing monitoring and management of cardiovascular risk factors will remain important after surgery.
When Is Carotid Artery Surgery Recommended?
Not every patient with a narrowed carotid artery requires surgical treatment. Whether carotid endarterectomy is recommended will depend on the degree of stenosis, whether the patient is experiencing symptoms and the anticipated benefits and risks of surgery.
In general, carotid endarterectomy may be considered for a patient with significant carotid artery narrowing, particularly if they have experienced a TIA, stroke or other symptoms associated with carotid disease.
When determining whether the patient is a candidate for carotid artery surgery, the vascular surgery services team will consider several factors, including:
- The severity and location of the carotid artery narrowing
- Whether the patient has had a TIA, stroke or related neurological symptoms
- The patient’s age and overall health
- The structure and location of the affected carotid artery
- Whether the patient has had previous neck surgery or radiation therapy
- Other medical conditions that could affect surgical risk
This evaluation can also help determine whether carotid endarterectomy, transcarotid artery revascularization (TCAR), another carotid stenting procedure or medical management is the most appropriate treatment.
How Does Carotid Endarterectomy Differ From Transcarotid Artery Revascularization?
Carotid endarterectomy and TCAR are both carotid revascularization procedures designed to treat significant carotid artery stenosis and reduce stroke risk, but they address the arterial blockage differently.
Carotid endarterectomy is an open surgical procedure that allows the vascular surgeon to directly access the carotid artery and remove plaque from inside the vessel. TCAR is a stent-based procedure that uses a smaller incision near the base of the neck. Rather than removing the plaque, the surgeon will place a stent across the narrowed area to hold the artery open. During the stent placement, the vascular surgery team will temporarily reverse blood flow in the carotid artery to help direct potential plaque debris away from the brain.
Carotid endarterectomy and TCAR have distinct roles in treating carotid artery stenosis, with the most appropriate option determined by individual clinical factors. The recommended approach will depend on the patient’s symptoms, degree of stenosis, age, anatomy, medical history and overall surgical risk.
What Happens During Carotid Endarterectomy?
During carotid endarterectomy, the vascular surgeon will make an incision along the side of the neck to reach the affected carotid artery. Blood flow through the treatment area will be temporarily controlled so the surgeon can carefully open the artery and remove the plaque from its inner lining. In some cases, the surgeon may use a patch to widen and reinforce the repaired area. After the plaque is removed and the artery is closed, blood flow through the carotid artery will be restored.
Throughout the procedure, the surgical team will take appropriate precautions to protect blood flow to the brain and reduce the risk of complications. The specific surgical plan will be tailored to the patient’s vascular anatomy and overall health.
What Is Recovery Like After Carotid Endarterectomy?
After carotid endarterectomy, the patient will be closely monitored for changes in neurological function, blood pressure and the surgical site. The length of the hospital stay can vary based on the patient’s health and recovery rate following the procedure.
Some soreness, swelling or numbness around the neck incision may occur during the initial recovery period. Before discharge, the patient will receive personalized instructions regarding incision care, medications, activity restrictions and resumption of normal activities.
Follow-up is an important part of recovery after carotid artery surgery. Carotid duplex ultrasound may be used to assess blood flow through the treated artery and monitor for recurrent narrowing. The patient should also continue taking prescribed medications and attending recommended vascular appointments.
What Are the Risks of Carotid Endarterectomy?
Like any vascular surgery, carotid endarterectomy carries certain risks. Potential complications include TIA, stroke, bleeding, infection, blood vessel injury, heart-related complications and nerve injury. Because several nerves involved in swallowing, speech and movement of the face and tongue are located near the carotid artery, temporary—or, less commonly, lasting—changes in these functions may occur.
Over time, the treated carotid artery may narrow again, a condition known as restenosis. Long-term surveillance can help the vascular surgery team identify changes in the artery and determine whether additional treatment is needed.
Before recommending CEA surgery, the vascular surgery services team will carefully consider the potential benefits and risks based on the patient’s degree of carotid stenosis, symptoms, overall health and individual stroke risk.
Why Is Long-Term Stroke Prevention Important After Carotid Endarterectomy?
Carotid endarterectomy treats plaque within a specific section of the carotid artery, but atherosclerosis can affect blood vessels throughout the body. Continued management of vascular risk factors therefore remains an important part of protecting long-term cardiovascular and neurological health after CEA.
Depending on the patient’s individual needs, ongoing management may include antiplatelet medications, cholesterol-lowering therapy or treatment for conditions such as high blood pressure and diabetes. Avoiding tobacco use, staying physically active and following a heart-healthy diet may also help reduce future vascular risk.
Regular follow-up visits and carotid ultrasound imaging can allow the vascular surgery team to monitor the treated artery for restenosis and evaluate the health of the carotid artery on the opposite side of the neck. Together, medical management, healthy lifestyle choices and ongoing vascular surveillance can help support long-term stroke prevention.
