Treatment of massive intraoperative brain swelling.

Massive intraoperative brain swelling is an infrequent but catastrophic occurrence. In this report, we describe the use of very large doses of thiopental as a means of treating such swelling. In our initial 11 cases (5 arteriovenous malformations, 4 hematomas, and 2 penetrating injuries), this approach produced the following outcomes: 6 patients made a good recovery, 2 are moderately disabled, 1 is severely disabled, and 2 are dead. These results indicate that this condition, which once was considered unmanageable, can indeed be managed and that treatment often results in an acceptable outcome. More recent experience in an additional 6 patients suggests that the use of planned deep thiopental anesthesia, with induced cerebral silence, during intracranial surgery may even prevent the occurrence of this phenomenon.

Ventricular obstruction secondary to vascular malformations.

Enlarged veins in two vascular malformations blocked the cerebrospinal fluid outflow pathways, causing hydrocephalus. Both patients presented not with the usual clinical picture (hemorrhage, seizure, etc.), but with signs of increased intracranial pressure. Computed tomography and angiography were necessary to understand the pathophysiology. An arteriovenous malformation was responsible for the first patient's headache, and a venous varix was the causative lesion in the second patient. Hydrocephalus caused by a venous varix has not been reported before.

Long term primary monolayer culture of adult murine magnocellular neurons.

Primary monolayer culture of adult murine hypothalamic cells has been carried out for 2 months. Neuron-like cells as well as fibroblast, glial, and ependymal-like cells demonstrated characteristic morphological features which distinguished them from one another. In addition, immunocytochemical identification of cytoplasmic substances cross-reactive with neurophysin and (8-arginine)vasopressin further characterized specific magnocellular neuronal populations throughout the culture period. This culture system should provide a basis for studying neurosecretion at the cellular and molecular levels.

Postoperative epidural hematoma as a complication of anterior cervical discectomy. Report of three cases.

In three cases, anterior cervical discectomy was complicated by acute postoperative paraplegia secondary to epidural hematomas at the operative sites. Prompt evacuation of the hematomas was followed by recovery in each instance. The source of bleeding was an arterial arcade that may be encountered during the course of removing the posterior longitudinal ligament. As a result of this experience, the authors suggest steps to be taken to avoid this uncommon complication.
