Ultrasound of cerebral vessels - indications for

For people who have suffered a stroke, it is very important to carry out ultrasound of the cerebral vessels , because the stroke is a direct consequence of the violation of blood circulation in the vessels. It is the conduct of this medical examination that will help the doctor to more accurately determine the possibility of the onset of a second stroke. Ultrasound of cerebral vessels can be carried out as prescribed by a doctor, and simply by contacting a specialized clinic. And already with the received results to address to the expert.

Before carrying out an ultrasound of the head, some preparation is necessary. It is quite simple, but it provides more accurate results when performing ultrasound of cerebral vessels. For several days before the study, you must refrain from eating, which affects blood pressure. It is not recommended to smoke before the uzi at least an hour, but better, of course, more.

Very often the study of the vessels of the brain is carried out together with the examination of the vessels of the neck. It is this survey that gives the most complete information about the blood supply to the brain, since blood flow is studied through vertebral and subclavian arteries, carotid arteries are being investigated.

The essence of ultrasound of cerebral vessels is that ultrasonic waves, passing through a blood vessel, are reflected in different ways. It depends on the number and speed of blood flow in a vessel. After that, the reflected reflected ultrasonic waves are converted into electrical pulses and displayed on the screen. Thus, the doctor immediately sees violations of blood circulation in the vessels of the brain and can determine exactly where their constriction or thrombosis occurs.

During an ordinary examination of the vessels of the brain, it is possible to determine only the patency of the vessels. But modern equipment allows for more detailed studies. For example, duplex scanning already helps to assess not only the speed of the passage of blood, but also to see, to study the anatomy of the vessels themselves, and triplex scanning also accurately estimates the patency of the vessels, which is displayed in color mode.

Carrying out ultrasound of the vessels of the head and neck allows:

- evaluate the blood flow rate in the blood vessels of the head and neck;

- conduct early diagnosis of disorders in the blood vessels, which are caused by atherosclerotic plaques and thrombi;

- accurately determine the place of narrowing of the vessels ;

- more accurately determine the causes of frequent headaches;

- carry out an early diagnosis of an aneurysm of the vessels of the head.

When it is recommended to carry out ultrasound of the head vessels:

- if the patient has complaints about frequent headaches, loss of consciousness, the presence of external noises in the head;

- with speech disorders and with the sudden occurrence of numbness in the legs and hands;

- if the patient has such diseases as hypertension, angina pectoris, cerebrovascular disease, diabetes mellitus, and vegetative-vascular dystonia and other chronic diseases;

- in the presence of high cholesterol and excess weight, as well as when there are changes in blood clotting;

- for people who are more than 40 years old, especially if close relatives have had cases of strokes, heart attacks, atherosclerosis, arterial hypertension;

- this procedure is also necessary for the preparation of the patient for the operation and for the effectiveness of the treatment already underway.

The examination of the cerebral vessels is absolutely painless and takes only about 45 minutes. Immediately after carrying out this study, the patient can lead his or her usual lifestyle. After carrying out the research, you get results in his hands, which the ultrasound doctor can decipher, but usually they are referred to a specialist who gave the direction for the research.
