Vascular ultrasound is performed at any age and is completely safe diagnostic technique. Prescribed for associated symptoms such as fainting, headaches, nausea, or in pathological conditions to determine the condition of major blood arteries supplying the brain.
What is the research?
Vascular ultrasound allows to determine not only their condition, but also to hear the noise of blood flow, making it possible to draw conclusions about regulation of the circulatory system. Echogenicity of red blood cells allows the ultrasonic signal to be reflected, thereby the device picks up these frequencies and represents them on the monitor in the form of graphs.
The result ultrasound allows the technician to determine the presence of any pathological processes that can affect the brain, and, if necessary, to appoint medical treatment, massage or physiotherapy.
How is vascular ultrasound?
For ultrasound blood arteries of a patient placed on a couch. Under the neck you need to enclose the cushion, so it was located in the correct physiological position, and none of the vessels was not perejimas and not twisting.
To improve the contact between the body of the patient and the sensor is used with a special gel. It is applied directly to the sensor. Then you can start conducting vascular ultrasound. That shows the device can only be decrypted by a specialist who knows the standards and versed in human anatomy (especially the circulatory system).
The duration of the ultrasound is not more than 30 minutes, the time of the study directly depends on the condition of the vessel. Interpreting the results is carried out in the study period, after this pictures and graphs are printed to provide to the attending physician.
Using the obtained results, the doctor will be able to make a conclusion about the state of the blood arteries and to determine the type of treatment (medical, surgical) or the need for bypass surgery.
Indications for research
Vascular ultrasound is performed upon detection of the patient's characteristic symptoms. It can be:
- fainting or frequent dizziness
- severe headaches
- myocardial infarction or stroke
- unhealthy lifestyle (particularly Smoking, especially in large quantities)
- high concentration of cholesterol in the blood
- suspected tumor masses
- preparing for scheduled surgery.
An ultrasound test of blood vessels of the brain resulting photos and graphs allow you to determine the condition of the vascular walls, to analyze the presence and location of plaque or blood clots. Also they can be used to detect brain pathology such as a fistula, malformations or aneurysms.
How is the interpretation of results?
Based on these results the doctor concludes the presence of compressions, atherosclerotic plaques, stenosis, perfusion disorders of the neck, head or brain pathologies that affect the patient's degenerative disc disease.
Normally, the conclusion must have the following characteristics:
- the lumen of blood vessels free
- turbulent blood flow is missing
- abnormal network of vessels is no
- signs of obstruction are absent
- the vertebral artery is the same
- blood flow through the veins is less than 0,3 m/s
- the thickness of the arterial wall is 1 mm
- the diameter of vertebral arteries is more than 2 mm.
Ultrasound of vessels of head and neck allows you to see the full picture of all the blood highways of these areas. With the help of which you can quickly diagnose a disease and effectively treat it, knowing where it is and in what stage of development.
Ultrasound for small children
Doppler shows children a very early age. In most cases it is performed in the hospital to determine the condition and operation of the vascular system of the child, in order to detect and eliminate possible pathology.
A study using ultrasound is not irradiated child is safe and painless method of diagnosis. Ultrasound of blood vessels of the brain reveals not only the condition of vessels, but also all soft tissues of the head and the body.
For examination, no preparation is necessary. It is important that lavorogenova child open sutures of the skull are present and the so-called fontanelles, allow you to examine it for the presence of soft tissue injuries (that sometimes occur during labour) or abnormalities of the brain.
The venue and the cost of the survey
Vascular ultrasound of the neck and head can be held in private or public clinics. To diagnose is not necessary to have a referral from a doctor, can be tested at will, as this method does not bear any harm to human health and is completely painless.
The cost of the procedure depends directly on the used equipment that can display two-dimensional or three-dimensional image. The most significant and complete is a triplex ultrasound of neck vessels, since it is modeled using accurate photos, fully corresponding to the real location and shape of blood vessels. Its average value in Russia varies in the range of 2,000 rubles.
