Vascular narrowing

Vessel constriction is a pathological condition triggered by accumulation on the inner vascular walls of atherosclerotic plaques. They are formed from blood cells, scar tissue, cholesterol and other fatty substances. With the growth of plaques, there is a narrowing of the vessels, which complicates the normal blood flow. In addition, they can form clots, which provokes a complete blockage of the artery.

One of the most dangerous consequences of the formation of thrombi and plaques that cause vasoconstriction is the ability to separate them from the walls."Traveling" through the bloodstream, they can penetrate the brain. In such cases embolism develops, which provokes the onset of ischemic stroke. In the case of bilateral carotid artery disease, the risk of such conditions is significantly increased.

Vessel constriction is a rather insidious disease. This is due to the practical absence of any manifestations in most patients. Together with this, when the signs of an ailment develop, the likelihood of ischemic stroke increases dramatically.

As practice shows, people with atherosclerosis, diabetes mellitus, elevated blood pressure, overweight, and also smoking and abusing fatty foods are most prone to this condition.

It should be noted the effect of hypertension on vascular health. The usual course of the disease is clinically divided at the stage. In the early development of the disease, unstable BP rises are noted, and normal pressure can be observed for a long period. In the first stage, patients tend to complain of irritability, weakness, sleep disorder, head and heart pain, and other common symptoms. The examination reveals, in addition to high blood pressure, in some cases a slight increase in the left ventricle, as well as a certain narrowing of the vessels of the fundus with a slight expansion of the veins.

The second stage of hypertension is characterized by a persistent increase in pressure. However, the above symptoms may be less pronounced, although headache, dyspnea, dizziness are often present. There is also true angina in lieu of heart pain of an atypical nature. The examination reveals an increase in the left ventricle, the arteries of the fundus are considerably narrowed, signs of their sclerosis are noted.

For diagnostic purposes, in detecting stenoses, ultrasonic dopplerography of the main artery sites in the head, electroencephalography or MRI can be used. Depending on the results of the studies, an optimal therapeutic course is prescribed.

It should be noted that modern medicine has a sufficient number of methods to eliminate the ailment. However, the most safe and progressive is the treatment of the vessels of the head with the help of stenting.

In this procedure, a special metal tube is inserted into the narrow area of ​​the artery, which consists of cells. The opening of the stent facilitates the expansion of the walls of the vessel, which are subsequently maintained in this state. Thanks to this, the blood supply improves and the internal lumen of the artery is restored.

Operative intervention is performed using local anesthesia and continues, as a rule, no more than sixty minutes. Sometimes patients can feel hot flashes in the head, the doctor can also ask the patient to move limbs.

The operation is completed by disposal of the vessels from the filters, the conductor catheter and the balloon( in case of its use).The wall is left in the artery to keep it open. After the intervention during the day, the patient is recommended a special regimen, from which the outcome of the operation depends.
