RESUMO
256 patients with radiologic detected cervical instability were examined. This pathology may be the cause of arterial or venous vertebra-basilar disorders. We realized extensive examination the patients with the cervical instability for the pathogenic correction of vascular consequences. We founded normal blood flow only in 19.9% cases without morphology alterations the vessels of both basins. 80.1% patients had different cerebral hemodynamic disorders variations. According to our examination plan we detected the vertebra-basilar insufficiency pathogenesis and proposed medicinal correction of the cerebral instability consequences.

We included 19 patients with a different intensity postoperative pneumocephalus and an inadequate postoperative awakening. Intracranial CT excluded postoperative complications (oedema, haematoma, hidrocephalus) and diagnosed a pneumocephalus (above the frontal and temporal lobes and in the cerebral ventricular system). In two hours after operation we found systolic linear blood flow velocity (BFV syst.) decrease in the extracranial part of internal carotic artery (ICA) (p < 0.001) in patients with pneumocephalus and inadequate postoperative awakening. But in 24-48 hours after operation we diagnosed BFV syst. elevation in the ICA extracranial part (p < 0.001) and preumocephalus diminution in patients with a recovered consciousness.
