REG of cerebral vessels: that shows the transcript of study
Rheoencephalography is a simple and effective test that can detect various abnormalities in the brain. At low cost research it has a high information content and fast results. Considering the changes in the blood vessels of the brain, REG allows with a high degree of accuracy in the shortest possible time clarify the diagnosis and is much more operational than the
Features REG research
With the help of reoentsefalografii doctors assess cerebral blood flow. Vascular tone and level of blood circulation in a certain area of the brain may help to identify developing disease and to start treatment immediately, without waiting for the development of severe stage of the disease.
Among the parameters REG is the speed of wave propagation of pulse, blood viscosity, flow and flow velocity, severity of the reaction vessels.
However, some doctors believe that the research methodology REG is hopelessly outdated and does not go to any comparison on the accuracy and completeness of the data obtained by tomography of the brain. This is partly true, but we cannot say that this study is entirely useless – it significantly clarifies the clinical picture and allows the doctor to prescribe treatment as quickly as possible, and is sometimes able to prevent a lethal outcome. Why doctors still prescribe this kind of research, among other contentious issues.
How is REG
The study is conducted with the help of rheograph – a special recording device. The procedure is as follows: the patient lies or sits in a comfortable position, closes his eyes at certain points on the head superimposed electrodes and fixed by rubber tapes. Often, to increase the sensitivity of the apparatus receiving part of the electrodes is covered with a special gel which acts like a conductor.
The patient should be prepared for the fact that the skin, which will overlap with the electrodes, the nurse will degreased with alcohol and then put contacts covered provodnikovym composition – this may cause discomfort. Then, during the procedure, is passed through the electrodes and a small current recorded readings of the resistance of brain tissue, which is then decrypted. The procedure with proper execution on the part of medical staff painless. However, the contact paste sometimes causes discomfort of its presence, but patients should not worry, as it can be easily washed.
The main difficulty in the research is that people under stress caused by the examination, very nervous, because the brow blood vessels constrict and the results can be unreliable. In order to avoid this, your doctor in advanceexplains the whole process and talks with the examinee in the process. By the way, the request to turn and move are not only psychological, but also practical use with the help of additional data about how to behave in the vessels of the brain when driving, it is possible to significantly Refine the diagnosis. Also, the doctor may ask you to breathe quickened, or hold your breath, squeeze the carotid artery to do any physical exercise. Sometimes for the greater reliability of functional tests are used nicotine or nitroglycerin resin.
REG for children
We should say about REG for children. The whole procedure lasts at least 10 minutes, sometimes stretched to half an hour. All this time the child has to sit or lie still, often with eyes closed to external stimuli does not distract. This amount of time able to sit, so doctors recommend or educational influence on the child, or not be screened at all, if the child is restless. Alas, here the restrictions are the same as for imaging. However, the task of the parent in this case is to tell your kid about why it is necessary and to convince him of the need to sit quietly. Importantly, the conviction did not happen by force and in a stressful situation, as the consequences of this will lubricate the whole picture of the study.
Transcript survey data
There are several characteristics of the data obtained: the shape of the waves, the amplitude, the presence and location relative to the downward main wave of additional teeth. The combination of these data help to distinguish what is happening in the brain organic changes from the negative, and for sure to know without penetrating into the skull where the lesion.
Wave has anekdoticheskuyu and catachrestically phase, that is, ascending steep and sloping downward wave, in addition cataquet has a special (discretioni) prong, which is usually located in the middle katakata. What do they mean?
The period of full disclosure of the vessel is shown with duration anakata in seconds, the value of systolic inflow shows a so-called rheographic index, and the tone of arterioles – microtechnique index, and blood flow and venous tone are shown with the diastolic index. Different pictures of rheoencephalography characteristic for different diseases, for example:
Why you need a REG
Rheoencephalography necessary in cases when you want:
- Diagnosis of lesions of cerebral vessels
- Controlling blood circulation in the brain after injuries or operations
- Evaluation of hypertension
- Assessment of the brain with TBI
- Assessment of brain encephalopathy
- Assessmentof the brain during a pituitary adenoma
- Assessment of the status of the brain after ischemia or stroke
- Detection of collateral circulation
- The search for the cause of indefinite symptoms
- The search for the cause of VSD and VDS
Because during the procedure there was no injuries in relation to the patient, REG is one of the most gentle and harmless methods of diagnosis.
Indications for REG
The EEG can be assigned in both diagnostic and preventive purposes, as totally safe. This is especially true for patients of Mature and elderly age, as over time the characteristics of the vessels are only getting worse and any pathology it is best to recognize in advance.
Which complaint doctors prescribe indications for REG:
- Dizziness different nature
- TBI and injuries to the cervical spine
- Bad heredity – the presence among the relatives of patients with lesions of blood vessels
- Vegetative-vascular dystonia
- Old age
- Atherosclerosis of cerebral vessels
- Weather dependent
- Unexplained hearing loss, vision, memory
This study resolves doubt in the diagnosis, and is formal in that case, if the clinical picture is more or less clear, but there remains the possibility of a medical error.
In addition, in combination with Doppler ultrasound the study could bet on the amount of information obtained with the imaging, while remaining more accessible and operational.
The benefits of reoentsefalografii
REG proven safe for health, which allows you to send the patient for an examination even if the preliminary diagnosis he is completely healthy, that is, as a preventive measure. Yes, it is used for quite a long time and may be considered outdated by some scholars, but its effectiveness is not in doubt.
To conduct the study does not need additional space lab, a lot of time and expensive equipment like tomography. The instrument is taking readings on the work of arteries and veins separately, which makes it easy to diagnose at any stage of the disease. Simple terms of the procedure and its painless for the patient are the main advantages in the question of which research methods should be assigned to juvenile patients.
For the observed elderly patients but this procedure is needed more often than for other categories, but it is available and it does not require high material costs, even when treatment in a private hospital.
Today REG is usedfor the initial examination of newborn infants, although data from these studies are seriously revised in connection with the specificity of the activity of the vessels of the human brain after birth and in the first year of life. The wave amplitude is small, anakata long, incisor is missing entirely and all that is the normal clinical picture of a healthy child. In all other cases, the patient's age makes no amendments to the transcript obtained in the study data.
Magnetic resonance imaging and computed tomography are more detailed, they provide a more complete picture of what is happening as Doppler ultrasound, however they are not as available to the public, and all the research may take excessively long time due to the lack of clinics equipment. But there are categories of patients for whom such research should be regularly – for example, in the postoperative period. Therefore, doctors do not cease to apply to reoentsefalografii.
The need for research
Quite often doctors prescribe REG as more research even when it is not particularly necessary. The safety of the procedure allows you to issue directions only for specification of the diagnosis the cheapest and the currently available means. It is difficult to say whether their actions are unjustified, but maybe not one life was saved thanks to REG, the doctors found lesions diseases of which the patient was unaware. Using this procedure is quite easy to detect a potential stroke condition, which allows doctors to promptly give the patient all the necessary assistance and to save his life and performance. So hard to give up REG – despite the fact that for a long time, there are far better ways to research vessels of the human brain, doctors have come to rely on familiar, habitual and almost never supply their means of verification. Naturally, this applies not only to "adult" doctors, and pediatricians, when faced with unsubstantiated symptoms and begin to suspect the child has a vegetative-vascular dystonia. The study in this case will allow us to help your child and provide him with a non-drug treatment at the stage when it is more effective and the disease does not prevent to live normally, developing complications to heart, lungs, Gastrointestinal tract and glands of the body.
