title: Disturbances of cerebrospinal fluid circulation during the acute stage of subarachnoid hemorrhage.
abstract: Radioisotope cisternography was performed and the erythrocyte and hemoglobin contents of the cerebrospinal fluid (CSF) were determined within the first 4 days after subarachnoid hemorrhage in 42 patients. The clinical condition of the patients was related to the severity of the CSF circulation disturbances. Thirty-five patients had some degree of disturbance of CSF flow, and only 2 of the 42 patients had normal flow. In 5 cases the cisternograms were inconclusive. The severity of CSF circulation disturbances correlated well with clinical condition. No relationship was found between the number of erythrocytes in the CSF and the development of CSF circulation disturbances. The CSF erythrocyte content did not correlate with the clinical condition. It is suggested that flow disturbances of the CSF during the acute stage of subarachnoid hemorrhage might play an important role in the pathomechanism of the disease.
