Abstract「要旨」全髄液腔, ことに脊髄腔の髄液循環動態を検討するため, 全髄液腔シンチグラフィーを施行し, 成人脳室拡大例18例に定量的検討を, 122例にフィルム上の臨床的検討を行った. その結果, (1)RI注入48時間後まで脊髄腔に停滞する例がある(spinal stasis:SS). (2)SSを示すのはventricular refluxのない例に多かったが, あってもSSが見られるときはシャントは無効であった. (3)SSは加齢により増加する傾向があり, (4)重症脳血管障害などに多く, 精神活動低下が強度な症例に多いなど高度の脳実質の障害が存在すると思われる症例に頻度が高かった. (5)SS群では全髄液腔のclearanceは著しく遅延していた. 脊髄腔の髄液流は頭蓋内の動脈性の拍動によるものと考えられるが, これらの結果からspinal stasisは脳実質の障害により髄液拍動流が低減している状態を示しているものと考えられた.

Abstract[Summary]Whole CSF-axis RI scintigraphy was evaluated in 122 adult patients intending to know not only intracranial CSF flow but also the dynamics of whole CSF axis, particularly of spinal CSF flow. The change of radioactivity in several compartments was studied quantitatively with a data-processor on 18 cases with dilated ventricles, and more practically, clinical features and the findings of the films were comparatively studied on all the cases. The results were as follows: (1) Roughly speaking, the findings were classified into two types, i.e. a type with early RI movement to the intracranial CSF space and another with stagnation of radioactivity in spinal space till late stage, even 48 hours after RI injection (spinal stasis). (2) Although majority of the cases with spinal stasis did not show ventricular stasis, a shunt operation was not effective even when ventricular stasis was observed. (3) Spinal stasis tended to increase with aging, and was observed more frequently in cases with possible severe cerebral damage, as severe cerebrovascular disease and severe deterioration of mental activity. (4) The clearance of radioactivity of whole CSF-axis was remarkably delayed. It is considered that the spinal CSF flow is generated by intracranial CSF pulsation and, so, that spinal stasis shows the condition of lowered CSF flow by pulsation due to cerebral parenchymal damages.
