Echoencephalography (EhoEg) of the brain

Echoencephalography (EhoEg) of the brain - a method of noninvasive diagnostic tool, based on the ultrasound reflection from the boundary of intracranial structures and the media with different acoustic density (soft tissues of the head, skull, meninges, brain matter, cerebrospinal fluid, blood). Reflect the structure may be abnormal formation (foci crush, foreign bodies, abscesses, cysts, hematomas, etc.).

Key indicator for echoencephalograph (EhoEG) - position of mid-brain structures (M-echo). Possible differences in the rate of cerebral admit physiological shift M-echo to 2 mm.

Echoencephalograph (EhoEG) used by our physicians in diagnosing the following diseases:

cerebral ischemia, stroke
vertebro-basilar insufficiency (VBI)
vegetative-vascular dystonia (VVD)
cerebral blood flow
dizziness
sonitus
intracranial pressure
headache (migraine, cephalalgia)
traumatic head and brain injury (TBI), concussion and brain contusion
injuries to the neck, cervico-cranial syndrome
encephalopathy
Parkinson's disease
pituitary adenoma

Of concussion in the displacement of midline structures echoencephalograph (EhoEG) does not exceed physiological abnormalities. In focal brain contusions, edema due to cerebral tissue, the displacement of the M-echo signal during echoencephalograph (EhoEG) toward the intact hemisphere may be 2-5 mm with a gradual increase in the 4 th day and has a tendency to regress within 1-3 weeks. In the area of injury on echoencephalograph (EhoEG) can register pikopodobnye signals due to reflection of ultrasound from the small focal hemorrhages.

Special znachenieehoentsefalografiya (EhoEG) acquires the compression of the brain. Possible early diagnosis of supratentorial meningeal hematoma, in which the displacement of midline structures of the brain in the direction of healthy hemisphere appears already in the first hours after head injury and tends to increase up to 6-15 mm. Often, echoencephalograph (EhoEG) observed a direct reflection of ultrasonic signals from the border between the hematoma and brain matter or the surrounding membranes of the brain. When you try to echolocation-side location of hematoma reflected from its boundary signal enters the initial "dead zone" and therefore echolocation hematoma is possible only on the opposite side.

Gematomnoe echo in echoencephalograph (EhoEG) is a pulsating high-amplitude signal, registering between low-amplitude signals pulsating from the walls of the lateral ventricles and the final complex (the reflection from the opposite wall of the skull of the sensor). Keep in mind that in case of damage, and edema of soft tissues of skull echoencephalograph (EhoEG) reveals a significant difference in distance to the final complexes, which often leads to errors in interpreting the results. In these cases, should be guided not by the initial and the final set of signals from the inner surface of the bone to the M-echo with subsequent determination of the magnitude of its displacement by the known formulas.

When bilateral hemispheric hematomas, hematomas in the posterior fossa, as well as lobnopolyusnoy and basal localization of hemorrhage volume diagnostic value method echoencephalograph (EhoEG) decreases, since losing its essential definition of the displacement of mid-brain structures. In these cases, the diagnostic capabilities of the multi-dimensional echoencephalograph (EhoEG), in which through the use of special nozzles eliminated "dead" space and is achieved by varying the input angle of ultrasound in a wide range.

In observing the dynamics of traumatic disease of the brain determine the size of the ventricular system (mainly on the value of ventricular index) and the magnitude of their fluctuations (as a percentage relative to the M-echo). Enhancing surge generally correlates with the increase of intracranial hypertension. Normalization of the surge and the size of the ventricular system in echoencephalograph (EhoEG) is an indicator of favorable flow of traumatic brain disease. The complete absence of pulsation in echoencephalograph (EhoEG) is an additional criteria that the stop of cerebral circulation in cases of terminal coma.
