That shows how to do Doppler ultrasound of vessels of head and neck of the child and the adult?

Doppler ultrasound of vessels of head and neck indicates what? This procedure is information form of the study of the arterial and venous branches passing out of the cranial cavity. TOOOhey are responsible for the normal functioning of the brain, its power and drain the blood. The study may be appointed in the case, when it begins to disturb neurological symptoms. It is advisable to study planning, this is done in order to minimize the risk of serious diseases. Before conducting the study required minimal training, the average time may vary from 30 to 40 minutes. The result can be obtained immediately, and the doctor will help him to decipher.

In the course of ultrasonic diagnostics specialists distinguish 2 major levels: the neck vessels and brain.

How goes the research? What features can you highlight? Some persons will be contraindicated diagnosis? The answers to these questions can be found below.

the Main stages of the study

To determine the current clinical picture of the patient, it is advisable to conduct a comprehensive study of both levels, i.e., the vertebral and cervical arteries, because there is a direct connection between them. Cervical blood flow represents an intermediate step of moving blood from the heart to the brain, and the brain – the result of this process.

It is Possible to diagnose violations at any of these levels, so it is important to conduct thorough research. The first stage aims to study the status of the cervical vessels:

1. Study all of the carotid arteries and their main branches.
2. analysis of the state of the spinal arteries, which are located in the cervical spine, the transverse processes of the cervical vertebrae. They carry the blood to target the brain.

The test can show possible obstacles, which can be both congenital and acquired. In the cervical spine, can often see convoluted vessels, which can form "loops" and convoluted passages formed by degenerative disc disease.

You Can see the narrowing of the arteries, either congenital or acquired. The study can be set loaned the diameter of the vessel, and possible inflammatory process that caused a negative change. In addition, the vessels could be formed in atherosclerotic plaques and thrombi, which may block the lumen of the artery. The doctor thoroughly inspects neck veins – jugular and vertebral, determining the outflow of venous blood from the brain to the heart.

The second phase begins a detailed study of the arteries and veins, which are located in the brain. The procedure is performed transcranial, that is, through the cranial bones. Arteries, which are located in the brain, cervical continue, focusing inside the skull. You can see the formation of two pools circulation: vertebrobasilar and karatnogo. Each of them has some differences that should be considered:

1. Charitably pool consists of terminal branches of the internal carotid artery. The study itself is conducted through the temporal bone.
2. Vertebrobasilar pool consists of final segmented vertebral arteries. Entering the cranial cavity, they merged.

This type of research helps to identify the results of the main indicators of cerebral blood flow. The blood supply may be unchanged or impaired due to detected problems with arterial blood flow (arterial spasm, insufficient blood flow). This type of research has received the name of TCD or transcranial ultrasonography of cerebral vessels.

Doctors do not recommend to explore the problems of vertebral arteries and cerebral vessels. You first need to determine the state of blood flow and development of the cervical arteries, as can occur a number of obstacles blocking the flow of blood.

If you explore the only vertebral artery, the study will not be considered complete, since will not be taken into account the resulting performance of the brain and cervical structures.

The Need for a separate study of cervical artery arises in the case of a dynamic increase of blood clots and atherosclerotic plaques that can be detected at early stages of development. This is to ensure that as soon as possible send the patient to vascular surgeons.

Doppler ultrasonography can help in the study of the individual levels of the bloodstream. For example, neck or brain, but it is not really the right solution.

Features Doppler ultrasound

Among the features of Doppler ultrasound studies can be distinguished:

1. Efficiency.
2. Informative.
3. Security (it is not contraindicated even a young child).
4. Simplicity.
5. Fast.

When this method is assigneddiagnostics?

In order to clarify the condition of cerebral blood flow, it is expedient to conduct the study only in case of existence of the following problems:

1. a bad headache.
2. decreased activity and prostration.
3. Insomnia.
4. Deterioration of sight and hearing.
5. ringing in the ears and head.
6. Stress and neuroses.

To prevent stroke, it is necessary to conduct prevention research that will be able to detect clots and atherosclerotic plaques. Doppler ultrasound shows the following groups:

1. Age more than 40 years.
2. Ischemic heart disease.
3. diabetes.
4. Diseases of the urinary system.
5. Patients who suffered a stroke/heart attack.

Duplex scanning cannot give high information. Understanding how to make a Doppler ultrasound, you can identify its competitive features. Upon detection of primary symptoms should immediately seek help from a doctor, who in the course of diagnosis to establish the possible cause of a disease and prescribe a comprehensive treatment.
