Intracerebral hemorrhage, hydrocephalus malresorptivus, peripheral nerves : [proceedings of the 43rd annual meeting of the Deutsche Gesellschaft für Neurochirurgie, Frankfurt/Main, May 10-13, 1992

**Advances in Neurosurgery** presents the experience and research results of modern neurosurgeons confronted with urgent diagnostic and therapeutic problems. The first topic here is spontaneous intracerebral hematomas, whose localization determines the form of treatment and usually its outcome. Newer therapeutic approaches such as stereotactic removal, endoscopy and fibrinolysis supplement the results of standard operative methods. Secondly, the hydrocephalus malresorptivus is covered, presenting experience with the diagnostic value of intrathecal infusion tests, CT-cisternography, evoked potentials, and MRI CSF-flow studies, as well as aspects of neurosurgical intensive care such as barbiturate treatment, respiratory problems in head injury patients, auto-regulation mechanisms, and hospital infection. The last section is devoted to peripheral nerve surgery, reports on experience with microsurgery and various forms of anastomosis in both traumatic and tumorous nerve lesions.
