DOPPLER EVALUATION OF CEREBRAL HEMODYNAMICS IN PATIENTS WITH CHIARI MALFORMATION I

Cerebral hemodynamics data in 86 patients with Chiari malformation type I (MKI), and 30 healthy subjects without neurological disorders was analyzed using the transcranial Dopplerography. The signs of cerebrovascular insufficiency in patients with MKI in the vertebrobasilar arteries pool have been revealed. Violations of cerebral hemodynamics were correlated with the severity and age of MKI patients. The greatest changes in cerebral hemodynamics were observed in patients with ectopic cerebellar tonsils more than 10 mm and the age above 50 years.
