Even in the recent past, the vessels of the head and neck remained inaccessible for investigation, because Through the bone tissue of the skull did not pass signals. Currently, this is possible, thanks to the invention of the diagnostic method of ultrasound dopplerography (UZDG), which is currently the leading method of examination for any diseases associated with impaired blood flow in the head and neck.
When it is necessary to carry out ultrasound of the vessels of the head and neck?
Indications for UZDG of the vessels of the head and neck:
- dizziness, fainting;
- migraine;
- noise in the ears , unsteadiness in walking;
- sleep disorders, fatigue;
- meteosensitivity;
- vegetovascular dystonia;
- symptoms of cerebral circulation disorders
- suspicion of circulatory disorders in pathology in the cervical spine;
- abnormalities of the vessels of the base of the brain, etc.
What is the ultrasound of the vessels of the head and neck?
UZDG is a diagnostic technique using the ultrasound method combined with Doppler. Dopplerography allows you to monitor the movement of blood through the vessels of the head and neck and in parallel to detect various disorders of blood flow.
The method of carrying out the research is based on the so-called Doppler effect. This effect is manifested in this way: the signal received by a special sensor is reflected from the blood cells. The frequency of the signal determines the rate of blood flow. After detecting a change in the frequency of the signal, the data are entered into a computer in which the state of the vessels and the problems with them are determined by means of special mathematical calculations.
What shows UZDG vessels of the head and neck?
This method includes the diagnosis of subclavian and vertebral arteries, carotid arteries, as well as major arteries in the brain.
Ultrasonic dopplerography can determine:
- blood flow velocity along the main arteries of the head and neck;
- level of atherosclerotic changes in the vessels;
- degree of stenosis of blood vessels;
- change in blood flow along the vertebral arteries in osteochondrosis ;
- the presence of an aneurysm of the cerebral vessels.
For the interpretation of the USDG indications of the vessels of the neck and head, it is necessary to have special training. Therefore, only a qualified doctor will be able to clarify whether there are deviations from the norm, according to the results of ultrasound of the vessels of the neck and head.
How is UZDG carried in the vessels of the neck and head?
To study the method of ultrasound of the vessels of the head and neck, there is no need for any special training. This technique is completely harmless and painless, has no negative effects, radiation load and contraindications.
During the study, the patient lies on a couch with a raised head. A special sensor is applied to certain points on the head and neck (in areas where the vessels being examined are closest to the sensor). Slowly moving the sensor, the specialist analyzes the image on the computer monitor, which gives a complete picture of the blood vessels and blood in them. The procedure lasts about half an hour.
Where to pass UZDG vessels of the neck and head?
Unfortunately, not all medical facilities are equipped with devices for ultrasonic dopplerography. And the cost of ultrasound of the vessels of the neck and head is quite high. It should also be noted once again that the proper conduct of the procedure for examining and interpreting the results is only possible with a high level of qualification of medical personnel. Therefore, it is recommended to conduct a survey only in those clinics that are equipped with modern technology, and where you can provide certificates that confirm the qualifications of specialists.
