[Status of cerebral ventricles and meninges in subarachnoid hemorrhage (clinico-pathomorphological studies)].

Long-term investigation of 64 patients with subarachnoidal hemorrhages (SH), 24 of which had subsequently died, and 2 series of experiments of animals with a single or repeated intracysternal infusion of various doses of autologous blood, yielded the description of the response of the meninges and ventricles at different terms after SH. The brain ventricles were measured by axial computer tomography and echoencephalography. A index of CSF resorption resistance and CSF pressure were determined. The cerebral meninges from experimental animals and autopsied human ones underwent the histological examination. The authors discuss the mechanisms of development of liquor dynamic disorders at different terms after SH.
