Carotid Artery Stenosis (Carotid-Artery Stenosis)

Carotid artery stenosis is a narrowing of the carotid artery that impedes the blood supply to the brain. As a result, a person may develop a stroke.

Causes of carotid artery stenosis:

1. Atherosclerosis is the deposition of cholesterol plaques on the walls of the artery, which leads to its narrowing. This is the most common cause of stenosis.

2. Inflammatory vascular diseases such as arteritis.

3. Carotid artery injury.

4. Tumor of the carotid body. In some cases, carotid artery stenosis is associated with this neoplasm.

Symptoms of carotid artery stenosis:

1. Dizziness, fainting, fatigue.

2. Numbness, weakness in the limbs, loss of coordination.

3. Speech, vision, hearing impairments.

4. Transient ischemic attack - short-term episodes of cerebral ischemia.

Diagnosis is based on duplex scanning of the carotid arteries, CT or MRI with contrast.

Treatment of carotid artery stenosis:

1. Drug therapy to prevent thrombosis (antiplatelet agents, anticoagulants).

2. Surgical treatment - carotid endarterectomy (removal of atherosclerotic plaque) or stenting (installation of a stent to expand the lumen of the artery).

3. Creation of bypass paths for blood flow if it is impossible to restore normal blood flow in the carotid artery.

Thus, in most cases, carotid artery stenosis can be effectively treated to avoid the development of a stroke. Timely diagnosis and adequate therapy are extremely important to prevent the disabling consequences of this disease.

Carotid Artery Stenosis (Carotid-Artery Stenosis) is a serious condition that can lead to stroke and other complications. The carotid artery is a large vessel that supplies blood to the brain. If a narrowing occurs in this vessel, blood cannot flow freely, which can lead to disruption of the blood supply to the brain and, ultimately, to a stroke.

Carotid Artery Stenosis can occur due to various reasons, such as atherosclerosis (deposition of fatty plaques on the walls of the artery), thrombosis (formation of a blood clot inside the artery), hypertension (high blood pressure) and other diseases. Some people may have a genetic predisposition to Carotid Artery Stenosis.

Symptoms of Carotid Artery Stenosis can range from mild headaches and dizziness to more serious problems such as vision loss, weakness in one side of the body, speech impairment, and others.

Treatment for carotid artery stenosis may include surgically removing the narrowed section of the artery (endarterectomy) or creating an additional bypass for blood to flow to the brain. Medicines may also be used to reduce the risk of blood clots and improve blood flow.

If carotid artery stenosis is caused by a carotid body tumor, surgical removal of the tumor may be required.

In general, Carotid Artery stenosis is a serious disease that requires prompt medical attention. Early detection and treatment of this disease can significantly reduce the risk of complications and improve the patient's prognosis.

Carotid Artery Stenosis (Carotid-Artery Stenosis, Carotid Stenosis): causes, symptoms and treatment

Introduction:
Carotid artery stenosis, also known as narrowing of the carotid artery or carotid stenosis, is a serious condition that can lead to loss of blood supply to the brain and a stroke. In this article, we will look at the causes of carotid artery stenosis, its symptoms and available treatments.

Causes of carotid artery stenosis:
Carotid artery stenosis usually develops due to the accumulation of atherosclerotic plaque on the inner wall of the artery. Atherosclerosis is a process in which fatty deposits, cholesterol and other substances form plaques on arterial walls, narrowing their lumen. As a result, narrowing of the carotid artery prevents normal blood flow to the brain. Rarely, carotid artery stenosis may be associated with a carotid body tumor.

Symptoms of carotid artery stenosis:
Often, carotid artery stenosis can present without any noticeable symptoms and can therefore be difficult to diagnose. However, in some cases, people with carotid stenosis may experience the following symptoms:

1. Ischemic stroke: Carotid artery stenosis is one of the main causes of ischemic stroke, which occurs when the blood supply to a certain part of the brain is disrupted due to an artery being blocked by a blood clot or embolus.

2. Transient ischemic attack (TIA): This is a temporary interruption of the blood supply to the brain that can cause short-term stroke-like symptoms, but with full or partial recovery of function within minutes or hours.

3. Cervical murmur: By listening to the patient's cervical area or using an ultrasound, the doctor may hear a murmur caused by unusual blood flow through a narrowed artery.

4. Vision problems: Carotid artery stenosis can cause vision problems, including loss of vision in one eye or blurred vision.

Treatment of carotid artery stenosis:
Treatment for carotid artery stenosis may include conservative methods such as lifestyle changes and drug therapy, as well as surgery.

1. Conservative treatment: Includes controlling risk factors such as smoking, high blood pressure, diabetes and high cholesterol. It is also important to maintain a healthy lifestyle, including regular physical activity, healthy eating and stress management.

2. Drug therapy: Your doctor may prescribe medications to help control blood pressure, lower cholesterol, or prevent blood clots. Examples of such drugs include antiplatelet agents (eg, acetylsalicylic acid), statins, antihypertensive drugs, and anticoagulants.

3. Surgery: In cases of significant carotid artery stenosis or if there is an increased risk of stroke, surgery may be required. The two main methods of surgical treatment are endarterectomy and stenting.

1. Endarterectomy: This is a procedure during which the surgeon removes atherosclerotic plaques and the narrowed section of the carotid artery, in

Carotid artery stenosis is a significant narrowing of this vessel under the influence of various factors, including the growth of plaques in the lumen of the vessel. This gives rise to circulatory failure and oxygen deficiency in the patient, which leads to a gradual deterioration of the condition. The pathology must be treated immediately, which is an extremely important issue, since the condition worsens over time. Usu
