[Extending informative value of intracranial pressure measurement by cerebral pressure amplitudes (Pa)--analysis of average intracranial pressure (Pm)].

One aim of the intracranial pressure measurement is observing constantly patients with intracranial space-occupying factors and therefore to act diagnosticly and therapeutically correct at the right time. Through the continual registration of the intracranial pressure amplitude in relation to the medium intracranial pressure it is earlier possible to forecast intracranial pressure rise and to deal with this than with just the simple measurements of medium intracranial pressure. With 40 neurosurgical patients such examinations were undertaken after implantation of a ventricle catheter. The value of this method was proven during the continual observation of the patient.

[The 100th anniversary of neurosurgery in Halle].

The habilitation thesis of Fedor Krause on an neurosurgical subject of March 9th, 1887, in Halle can be considered to be the beginning of a scientifically practiced neurosurgery in Halle. Gustav von Bramann continued this tradition at the university until 1913. His successors Schmieden, Voelker and Wagner showed less interest, so that it finally was Alexander Stieda who led neurosurgery to an new climax at the municipal hospitals Weidenplan in the period from 1919 to 1950. After the Second World War the new constitution of neurosurgery was started at the Surgical University Clinic under the direction of Budde, Mörl, and Schober. When in 1970 it became a special department which existed until 1974 under the direction of Kurt Hübner, later-on Dieter Tertsch, the basic condition of a clearly defined efficient discipline was provided.

[Ultrasound tomography following surgery of tumors of the cerebellopontile angle].

After operations of the posterior fossa, ultrasonic tomography is a suitable noninvasive imaging procedure. After osteoclastic trepanation 45 patients were investigated with ultrasonic tomography. Below it were 18 patients with tumours of the cerebellopontine angle. A sector probe with a frequency of 3,5 MHz was used for the sonographical procedure. Ultrasonographical cross-sectional images were produced from occipital-retroauriculare or suboccipital. Solid processes have a definable echodense structure. Cystic processes and substantial defects of the brain are echopoor or echofree. Ultrasonic tomography allows an aimed application of CT controls.

[Ultrasound tomography in postoperative monitoring of infratentorial space-occupying lesions].

After osteoclastic trepanations of the posterior fossa for cystic or solid processes of the cerebellum and the cerebellopontine angle, ultrasonic tomography is a suitable imaging procedure. A mechanical sector probe with a frequency of 3.5 MHz is recommended as transducer. The postoperative ultrasonic findings are the basis for the sonographic observation of the further evolution. Cystic and solid processes can be localized and their dimensions metrically determined by means of multiple plane cross-sectional imaging. Ultrasonic tomography is recommended as a primary diagnostic method owing to its lack of invasivity and radiation exposure, simple handling and repeatability. As a consequence, CT examinations can be better aimed.

[Transabdominal lumbal ultrasonic tomometry--sonographic measurement of the lumbar spine].

Transabdominal sonography was carried out on 102 lumbar segments that were myelographically without abnormalities of the dural sack. A sector probe with a frequency of 3.5 mHz was used as transducer. Diameters of lumbar discs and lumbar canal were measured in a transversal plane. Echogenicity of the epidural fat in the lumbar canal allows to depict both the limitation of the dorsal outline of the lumbar discs and the dorsolateral vertebral arch. The following mean values were calculated for the spinal canal: Sagittal diameter-L5/S1:18.5 mm, L4/5:20.4 mm, L3/4:19.9 mm Transversal diameter-L5/S1:20.9 mm, L4/5: 21.4 mm, L3/4:21.2 mm Sonographic measurement of the spinal canal is possible.

[Spinal ultrasound tomography in the diagnosis of lumbar intervertebral disk displacement].

By comparative sonographic and myelographic investigations of 61 patients with lumbar disc herniations and other nerval compressive syndromes, the value of the spinal sonography in the diagnosis of lumbar disc herniation is demonstrated. The transversal transabdominal representation of lumbar disc herniations is successful in 82% of all cases. The sensitivity of sonography amounts to 0.73 in the segment L5/S1 and to 0.92 in the segment L4/5. In connection with the neurological investigation and X-ray films of the lumbar spine, the spinal sonography as a noninvasive procedure can represent an useful alternative to the myelographic diagnosis of the lumbar disc herniation.

[Ultrasound tissue emulsification of brain tumors].

A report is given on the design of an equipment combination developed in co-operation with the Central Institute for Welding Technology of the GDR, by means of which cerebral tumour tissue can be emulsified and sucked off. The suitability of the equipment was tested experimentally and confirmed in clinical application.

[CNS involvement in primary angiitis--personal clinicomorphologic studies of 6 cases].

We report on the clinical symptomatology, diagnostic difficulty and inadequate possibilities for treatment of 6 patients suffering from primary agiitis of intracranial vessels. They died at age 36 to 64 years. The duration of the disease varied between 6 weeks and 11 1/2 years and was diagnosed, autoptically in all cases, as giant cell angiitis (2 cases) and, trombangiitis obliterans (4 cases). A degenerative cerebrovascular process had already been assumed clinically in four of the cases, and intracranial veins were also involved in three (very distinctly in one). The vascular disease was generalised or multilocular in four observations. Although autoimmunological processes were probably involved, the etiopathogenesis is still, in the final analysis, more or less unknown.

[Surgical stabilization of fractures of the thoracic and lumbar portion of the spine using paraspinal metal plates].

Surgical treatment of lesions of the vertebral column is indicated for concomitant disturbed neurological functions showing an increasing tendency. In cases of a primary complete transverse paralysis, an improvement cannot be expected. The influence of the applied paraspinous plates on the rehabilitation is judged differently. The operation is carried out from a dorsal access. After laminectomy and decompression of the spinal marrow or cauda, stabilisation is effected by means of two paraspinous osteosynthesis plates similar to the method after Roy- Camille . Our own procedure is described, the results are demonstrated by the example of seven patients treated in this way. The authors are of the opinion that it is justified to continue employing this method and extend the range of indications to include also severe instable luxation fractures of the thoracic and the lumbar part of the vertebral column without disturbed neurological functions being present . The care of such patients is facilitated by the fact that pain is improved and degenerative changes and late damage prevented.

[The function of the fluid compartment. Part I].

Expansion of the cerebrospinal-fluid space is a new conception introduced in view of the fact that in the closed cranial cavity in case of an increase in cerebrospinal fluid the relation volume/pressure undergoes characteristic changes. The physical laws resulting from this have already been considered in the Monro-Kellie doctrine and concern the three main parts of the cranial cavity: brain, cerebrospinal fluid, and vessels. The capability of compensation, the compliance and the elasticity or elastantia of the cerebrospinal-fluid space can be measured on the basis of the dynamic changes proceeding in the space, the pressure/volume index (PVI) being a measure of the degree of filling of the intracranial space.
