Spinal cord electrical stimulation is a method of pain treatment. Although an increase of cerebral blood flow after high cervical spinal cord stimulation has been shown in various experimental and clinical studies, the mechanism of this effect is still controversial. Widely accepted explanation is reversible inhibition of cerebrovascular symphatetic activity after high cervical spinal cord stimulation. The aim of this study is to investigate the reliability of this hypothesis. For this purpose, spinal cord stimulation was performed directly in one group of rabbits, and after cervical symphatetic ganglionectomy in another group. Cerebral blood flow changes in experimental groups are srndied by transcranial Doppler ultrasonography. The results of this study revealed that cerebral blood flow changes after spinal cord stimulation are not solely dependent on symphatetic inhibition.
