[Blood supply function and the tonus of the cerebral vessels in cervical sympathetic ganglionitis].

In 42 patients with cervical sympathicoganglionitis and secondary diencephalic dysfunction, the cerebral circulation was studied by REG in order to elucidate the role of vascular factor in the pathogenesis of diencephalic impairments. The authors established the persistent elevation in the tone of the cerebral vessels in the carotid and vertebral-basilar area and a decrease in the pulse blood filling. The nitroglycerin test indicated the functional nature of the changes. A clear-cut vasculodilating effect following therapy with gangleron administered in the area of the impaired ganglia by graded electrophoresis was observed. It is suggested that vascular factor is involved in the pathogenesis of secondary diencephalic dysfunctions.
