Forty patients with cervico-omo-brachial syndrome, twenty with cervical spondylotic myelopathy, twenty cervical spondylotic radicuolpathy and 20 normal controls were selected for this study.
After catheter for cevrical epidural anesthesia had been placed in the cervlcai epidural space of these cases, circulation of the epidural space by R. I. and cervical peridurography were examined.
From the results of our study, we suggest that one of the causes of cervico-omo-brachial syndrome is the lesion of the root area or unstable circulatory dynamics of the cervical epidural space.
