Carotid artery stenosis

Carotid artery stenosis

 Carotid artery disease occurs when certain substances accumulate in the largest Harianin in the neck, and thus hinder the flow of blood to the brain. This condition is also called carotid artery stenosis in some cases. When blood flow to the brain obstruction occurs, it causes a stroke. Clogged arteries in the neck can lead to strokes.

Carotid artery disease does not cause any symptoms in its early stages usually, as people do not know that they have a problem usually become infected even stroke. Strokes can be dangerous, even fatal at times. Treatment options may include lifestyle changes and use of medicines; there may be a need to undergo surgery in severe cases.

an introduction

It can result in the accumulation of certain substances within a larger Harianin in the neck to impede or stop supplying the brain with blood. This is called carotid artery stenosis or carotid artery disease. Clogged arteries in the neck area may cause strokes. This educational program helps to understand the carotid artery disease better, also helps to know its causes, and its complications, and diagnosis, and how to treat it.

  Overview of the anatomy of the carotid arteries

The Aaouan Dmoyan and senior, were in the front of the neck, to supply the brain with blood. These are called Aluaaouan Aldmoyan as the arteries intercarotic. The Aharianan Sbatiyan connect the blood to the arteries in the brain.

Symptoms of carotid artery stenosis, causes

 Carotid artery disease does not cause any symptoms in its early stages, people do not realize that they suffer from the problem usually even at risk of stroke. You get a stroke when the brain does not receive enough blood. May cause a sudden decrease in the amount of blood that reaches the brain a "small stroke" occurs, or the so-called Nubia ischemic cross "or" heart ischemia transit. "May include symptoms of a heart ischemia transit a sense of numbness, weakness and difficulty in speech or vision.

 These symptoms do not last only a short period of time. Strokes occur when a shortage of linking the amount of blood to the brain lasts a long time. It can result in brain damage caused by stroke to loss of speech or consistency. That may require hospitalization. It can cause large die strokes, too. Every year about one-third of people who have already suffered transient ischemic attacks to strokes more dangerous in the future.

 When blocked artery, the blood can not reach the brain. So it seems natural if the artery has been cut in half. Note the smooth walls of the artery. Arteries look that's when children and young people. It can clog arteries by plaques consisting of cholesterol, cells and debris, and other materials.

When this plaque layer thickens, do not reach sufficient quantity of blood to the brain. This condition is called atherosclerosis. It can be separated a small piece of plaque on the artery wall, and float with the blood moving until it reaches the brain. This piece can be included in one of the small arteries within the brain, and close it, causing occurrence of stroke.

 Diagnosis of carotid artery stenosis

Since the carotid artery disease does not cause symptoms in its early stages, it is necessary to conduct regular visits to the doctor to detect problems early. Signs of carotid artery disease, which can be detected through a routine clinical examination, are:

     The voice is like Puff called "ado", issued by the carotid artery.
     The presence of pieces of cholesterol in the blood vessels in the bottom of the eye.

 Can the doctor examined the arteries by Doppler test "echo Doppler planning," an examination depends on the acoustic waves that rebound reflected from blood cells, so as to create moving pictures of the blood stream. The doctor also may request an X-ray examinations being during which special dyes injected into the arteries. These dyes and make the arteries visible when you take pictures. One of these tests:

     Magnetic resonance angiography.
     CT angiography.
     Cerebral angiography.

 The treatment of carotid artery stenosis

If the blockage in the carotid artery mild, the patient's doctor may recommend some changes in the pattern of his life to prevent the emergence of the blockage and the incidence of strokes. These include changes in lifestyle include:

 stop smoking.
     Eating healthy food that contains a small amount of fat.
     Enjoy a lively and active and exercise.
     Refrain from eating salt.
     Blood glucose control if a person is sick with diabetes.
     Maintaining blood pressure within normal limits.

You can resort to the use of medicines also to address some of the causes of carotid artery disease, and the use of drugs the doctor advised for:

     Lower blood pressure.
     Lowering cholesterol.
     Prevent the formation of blood clots.

The doctor will discuss with the patient the right to his medications. But you must not resort to any therapeutic regimen without first discussing with your doctor, including those medicines sold by non-medical normally recipe. You may need to resort to surgery if the medication did not work and lifestyle changes to control or treat carotid artery disease.

  The carotid endarterectomy surgical procedures most commonly used for the treatment of carotid artery disease, where the doctor during this procedure to open the carotid artery through an incision in the introduction to the neck, and then opens the carotid artery, the patient, removes plaque from the interior walls. It may not be possible to carotid endarterectomy in some cases, and then the doctor may Aajra so-called "bridge or expand the artery," with a brace.

 During the angioplasty process removing the blockage and open the artery using a balloon, then a pillar to keep the artery open and strengthen placed. Typically this is done by long catheter entry in Alhraiaan. This type of action does not need to make an incision in the neck.

Conclusion

Carotid artery disease occurs when certain substances accumulate in the arteries in the neck area. That could lead to a reduction of blood supply to the brain or cut off this supply. Leads the brain stops blood supply to the occurrence of stroke.

 The Strokes can be dangerous, even fatal at times. The doctor may do some of the clinical examination and x-ray tests to help diagnose carotid artery disease.

  Could remedies include changing the pattern of the patient's life and taking certain medications. It may be necessary to perform surgery in severe cases. The patient can be asked of his questions and inquiries about carotid artery disease on the health care provider in the place of residence.
