    Abstract:
    Cerebrospinal fluid flow dynamics of 15 patients with occlusive cerebrovascular diseases was studied using RI cisternography (RIC) and Metrizamide CT cisternography (CTC) and these methods were compared. RIC demonstrated RI retention in 9 patients, which was noticed in all chronic stage patients (over one month after apopletic episode). Five patients had subarachnoid block in affected cerebral hemisphere. Ventricular reflux, however, was present in only one patient. Metrizamide CTC (170 mgI/ml) showed ventricular reflux or stasis in 11 of 16 patients. Seven patients revaaled asymmetrical metrizamide filling of Sylvian fissures at 3 or 6 hours after intrathecal injection of Metrizamide. Asymmetrical demonstration of Sylvian fissure after 3 hours in 3 patients corresponded with the finding of subarachnoid block at the same side on RIC. The clinical values of CTC were emphasized on the basis of this investigation. Ventricular reflux or stasis, which indicated one of the important findings on cerebrospinal fluid flow disturbance, was easily and clearly detected. Asymmetrical metrizamide filling of Sylvian fissures at 3 hours after injection was compatible with subarachnoid block on RIC.
