Circulatory disturbances and pathological changes in the vessels lead to serious health problems and often cause a stroke. One of the most effective methods of examination of the state of the vessels of the brain is doppler (Doppler sonography or doppleroscopy). The procedure is based on the analysis of ultrasonic signals produced by a special device, reflected from elements of human blood.
Doppler directivity of blood vessels
To make a doppler of vessels of a brain the doctor recommends at:
- chronic headaches;
- dizziness;
- violation of coordination of movement and motor functions;
- increased intracranial pressure;
- vegetative vascular dystonia ;
- persistent pathologies in the emotional sphere and a number of other alarming symptoms.
Doppler sonography helps diagnose:
- vascular damage (even in the early stages);
- change in the tone of venous vessels;
- arterial stenosis (narrowing);
- disorders in the bloodstream, mainly, the formation of blood clots (thrombi);
- development of atherosclerosis;
- increased intracranial pressure;
- vascular malformations, including aneurysms .
Organization of the procedure of examination
Doppler of the vessels of the head - the procedure is painless and practically harmless is carried out like an ultrasound examination. The patient is lying in the supine position, while the head is placed on a special pillow. Before the procedure begins, the head and neck area to be examined is treated with a gel that provides the best possible skin contact with the sensors. A tightly pressed sensor moves slowly over a certain area.
With the doppler of the brain, the apparatus fixes signals reflected from the walls of the vessels, and also determines the speed of the current
Nowadays, the Dopplers with the analytical function, connected to the computer system, which are controlled by the touchscreen, are becoming increasingly widespread. Prior to the start of the procedure, the patient is informed about the patient. The analysis and interpretation of the results is carried out by a specialist. If necessary, a re-examination can be performed to determine the dynamics of the processes occurring in the vessels of the brain.
