UZDG - what is it? Indications for prescription

Recently, doctors are increasingly appointing a procedure for USDG. What is it - not everyone understands, and cumbersome abbreviations sometimes lead to a state of shock.

How to decipher abbreviations?

Understand the principle of operation and mechanism of USDG(what is it and how to treat it) will help deciphering: ultrasonic dopplerography of vessels. This is a modern method of ultrasound examination of internal organs, based on the Doppler effect.

UZDG MAG - what is it? Scanning of the main arteries of the head, which allows you to analyze the speed and nature of the bloodstream of the main vessels of this zone.

UZDG BTS - what is it? This is an informative method for detecting vascular anomalies of diseases and the head and neck.

UZDG BCA - what is it? This is similar to the previous study. The term BCA (BTS) means brachiocephalic arteries (trunk). The method is aimed at examining an arterial vessel of large caliber that extends directly from the aorta that carries blood to the brain. Brachiocephalic artery three: sleepy, vertebral and subclavian.

The mechanism of work

UZDG is a combined study combiningthe standard procedure of ultrasound and the Doppler effect and allows you to view both the state of the vessels, and the nature of the movement of blood over them. Ultrasonic angiography is carried out by means of sound waves penetrating to a certain depth of the patient's body. This procedure is absolutely painless. Inaudible sounds of the human ear are emitted and captured by a special sensor. When reflected from the vascular wall, information is converted by the computer into a black and white two-dimensional image. Doppler reflects on the screen moving objects (red blood cells) in the form of a color picture. When they are superimposed on each other, a picture of USDG is obtained.

Preliminary preparation and safety of the study

With the help of UZDG it is possible to determine the state andthe nature of the blood flow in the vessels of absolutely any caliber - from large veins and arteries to the smallest capillaries. This method of examination refers to non-invasive procedures. For the study, there is no need to disrupt the integrity of the body's structures (for example, as with laparoscopy, when a puncture is made to access the laparoscope, or contrast research using X-rays, when it is necessary to introduce a certain substance into the lumen of the vessel). This characteristic makes the USDG as convenient for the patient as for the doctor (there is no need for complex manipulations).

Before the study there is no need for a specialpreparation - the process procedure resembles a conventional ultrasound. The patient should take a comfortable position on the couch and expose the area under investigation. The USDG is allocated from 20 minutes to 1 hour.

This survey is shown to people of anyof age, it can be produced even by newborns, because radiation exposure to the body does not occur. Ultrasound is considered a safe and highly informative method of investigation.

The structures investigated with the help of UZDG. What is ultrasound angiography?

With the help of this medical procedure it is possible to reveal the state of the following body structures:

• the lumen of the vessel;
• degree of tortuosity;
• the state of the vascular wall, its integrity and the presence of seals;
• abnormal narrowing (stenosis);
• functional valency of the valvular system of veins and the presence of defects;
• protrusion of the vascular wall;
• obliteration (blockage) of the lumen of the vessel by a thrombus or foreign body;
• blood flow quality - availability, speed, turbulence.

Ultrasound angiography is the second name of UZDG, more common, but less capacious.

At what pathologies is appointed UZDG?

What is it, we dismantled. But at what pathological conditions is it expedient to prescribe this particular procedure in order to obtain the most complete and reliable information?

1. Blood pressure jumps. This method is informative both for hypertensive crises and for collapoid states.
2. Stubborn, not amenable to drug therapy headache. You can assign UZDG cerebral vessels and the patient who suffer from periodic migraine attacks.
3. Stenocardic pain, a sense of lack of air, swelling - all these signs of disruption of the cardiovascular system. They are direct indications for ultrasonic angiography.
4. Explicit signs of circulatory failure in the limbs (with diabetes, obliterating endarteritis, Reynaud's syndrome and other vascular and systemic pathologies).
5. Repeated syncope and other signs of brain damage. Sharp loss of vision.
6. Persistent causeless insomnia.
7. Vascular aneurysm.
8. Phlebeurysm.

The USDG study is carried out in real time, there is no need to wait for a long time.
