Diagnostics of pathologic cerebral hemodynamics at patients with intracranial vascular malformations
The signs, parameters of EEG, transcranial Doppler investigation, computer and MRI tomography of brain at 182 patients with intracranial vascular malformations are analyzed. The received results have allowed allocating 3 groups of criteria of the non-invasive diagnostics of vascular malformations on prehemorrhagic stage. Authentic diagnosis is considered, when the data on malformations localization of any of four listed methods completely coincide with the data of three others. The diagnosis becomes probable at concurrence of the given three methods and presumable at concurrence of the given two methods and an opportunity of reception of an explanation to the mechanism of discrepancy of the data of the third method.
