Dopplerography of vessels of head and neck

Doppler is a modern method of diagnosis of vascular disorders. Doppler measures the sound waves reflected from moving objects. A computer program analyzes the information and creates a two-dimensional color image showing the possible difficulty in blood flow. It helps to identify blood clots or atherosclerotic plaques.

How does it work?

Unlike the old Doppler equipment, modern technology combines ultrasound imaging and Doppler. The apparatus processes information obtained through these two methods, and describes the structure of the vessels. This technique is called laminated study. In triplex, the study combined assessment of blood flow, its speed, the size of the lumen of the vessel and amount of obstruction. This comprehensive examination allows us to precisely determine the condition of the arteries and veins, to make the correct diagnosis.

Classical ultrasound is applied by using sound waves not audible to man. They pass painlessly through the patient’s body, reflected from the blood vessels and their content. The unit analyzes received information and generates too two-dimensional, but black-and-white image (B-mode). In modern technology combined the two methods, and each ultrasound machine equipped with a Doppler.

Hypertension is no longer a disease?

  • problems with coordination of movement and balance;
  • dizziness;
  • headache.

Dopplerography of vessels of head and neck shall also be patients at risk. So, if immediate family been diagnosed with hypertension, atherosclerosis, myocardial infarction or stroke and the patient is more than 55 years, is recommended to perform Doppler examinations. The methodology is assigned and people that are poorly adapted to the environmental conditions: do not bear the change of weather, experiencing «motion sickness», hard to bear travelling.

Doppler blood vessels of the head and neck in children

In addition to the above symptoms and diagnoses, children examination is assigned when certain characteristics of the development. Doppler helps to identify causes of delay in the formation of speech, deterioration of memory and attention. In addition, the survey results clearly show the picture of the disease, when restlessness or, alternatively, by inertia and fatigue.

How is the procedure?

Doppler blood vessels of the head and neck does not require prior training. It can be performed any day and any time of the day. The only prohibition is not to drink alcohol or smoke just before the Doppler ultrasound, as this may affect the results. For the same reason, short-term cancel medicines affecting the blood flow. The survey is conducted as an outpatient in the clinic, in the office of ultrasonic diagnostics. Procedure the doctor performs either ultrasound or vascular surgeon, depending on the complexity of the particular case.

Doppler blood vessels of the takes only 10 – 20 minutes, depending on the pathology. When not appointed triplex ultrasound contrast agent, which eliminates unnecessary discomfort during the procedure. Doppler ultrasound has no contraindications and complications, so the range of possible patients is very wide.

The patient lies on the couch and gently lifts his head. Neck, and lower parts of the scalp gel is applied — it improves the transmission of ultrasonic waves. Doctor of ultrasonic diagnostics presses the sensor to the skin at the place of examination and easily move it back and forth. It does not cause any unpleasant feelings. Depending on the investigated area, the doctor may give special instructions: rotate the head in one direction or another, to hold the breath or on the contrary to breathe more often. The sensor sends to the computer signals, and he, in turn, converts them into a picture. The result is displayed on the monitor. A whistling sound that one hears during the test is sound, and shows the movement of blood.
