Upper cervical sympathectomy in neurovascular pathology.

Abstract

The effectiveness of upper cervical sympathectomy in the treatment of patients with neurovascular pathology has been discussed in the researcher’s article for many years. However, the indications for this surgery need still to be clarified. The dynamics of cerebral blood flow during sympathetic blockade could not become the significant criterion for determining indications for surgical treatment. A cerebral perfusion pressure change in neurovascular pathology can activate the neurogenic mechanism of cerebral blood flow regulation. The need to search for new methods for the intensity of the autonomic nervous system impact on the cerebral vessels tone (the neurogenic mechanism of cerebral blood flow regulation) to clarify the indications for upper cervical sympathectomy in patients with neurovascular pathology is justified. The review put forward a hypothesis about the relationship between intracranial B-waves amplitude and the state of the neurogenic mechanism of cerebral blood flow regulation.
