[The detection of cerebral circulation changes in children by Doppler ultrasonography in ambulatory care].

To determine the role of ultrasonic and transcranial dopplerography in investigation of both arterial and venous systems of children's head in conditions of outpatient clinic were observed 100 children aged 4-14 years with autonomic dysfunction, migraine, neurosis-like and closed cerebrocranial trauma (concussion of the brain). There were estimated the qualitative indices of dopplerography (a form, distributions of the frequencies in spectrum, direction of the blood flow, acoustic characteristics) and quantitative indices (systolic, diastolic, mean rate of blood flow, indices RI and S/D) and alterations in venous circulation. In all the groups of children there were found angiodystonic manifestations in the form of the increase of vessels resistance in 87.5-97.6% of the patients; besides, the signs of venous dysgemia were observed in 28-50% of the cases.
