[The diagnosis of arteriovenous malformations of the brain by transcranial dopplerography (the dopplerographic semeiotics of arteriovenous malformations)].

The work is devoted to investigation of possible use of transcranial dopplerography as a method of noninvasive diagnosing of arteriovenous malformations of the brain. An analysis of results of investigations in 89 patients with suspected arteriovenous malformations was made. A close correlation is confirmed between the parameters of the blood flow and the volume, diameter and type of the structure of the supplying arteries. Transcranial dopplerography was shown to allow the detection of arteriovenous shunts in the brain vessels which is one of main symptoms of the arteriovenous malformations.
