[Liliequist membranotomy for patients with ruptured intracranial aneurysms (author's transl)].

In order to reconstruct the blocked CSF pathway, we attempted to excise the Liliequist membrane in 22 patients with subarachnoid hemorrhage resulted from ruptured intracranial aneurysms. After clipping the aneurysmal neck, the Liliequist membrane was reached through the space between the optic nerve and the internal carotid artery within the same operative field. As a result, the incidence of postoperative ventricular dilatation was remarkably reduced in comparison with control cases without Liliequist membranotomy. The necessity for the shunt operation for post-SAH hydrocephalus was also reduced. On the other hand, the incidence of postoperative subdural effusion increased in the group with Liliequist membranotomy. This suggests that the blockage of the arachnoid villi is probably the cause of disturbances in CSF absorption in some cases following subarachnoid hemorrhage. In such cases, the Liliequist membranotomy may be ineffective in restoring CSF circulation following subarachnoid hemorrhage.

Epidemiological studies on patients with a persistent vegetative state.

Persistent vegetative state after severe brain damage was studied epidemiologically in 110 cases from 1973 to 1976. The causes of brain damage were varied. More than one-third of the cases were due to trauma, and about one-fifth were the result of vascular accidents. Three year observation revealed that 65% of the patients died during this period. Mean survival time for dead patients was 38 months. Reactivity, clinical signs, EEG findings, methods of management, and results of various trials of treatment were investigated in connection with the patient's prognosis.

Epidermoid tumor of the lateral ventricle.

The authors present a case report of the successful removal of an epidermoid tumor of the temporal horn of the lateral ventricle. The tumor was confined to the ventricular cavity and was not adherent or connected to the choroid plexus. Spilling of tumor material during surgery was presumed to have contributed to the development of a postoperative acute hydrocephalus, either by obstructing the cerebospinal fluid pathways or by causing an aseptic meningitis in conjunction with cholesterol in the ventricular fluid in the postoperative period.
