[Hemodynamic monitoring in microneurosurgical excision by sub- and retro-sinus approach in seated position in acoustic neurinoma].

Haemodynamic data (thermodilution Swan-Ganz catheter and radial artery cannula) were collected in 17 patients (52.4 +/- 8 yr) during retrosigmoid approach for removal of an acoustic tumour in the seated position. Measurements were made before stimulation of posterior fossa structures (period 1) and during tumour dissection along the brain stem (period 2). Significant increases in systolic, diastolic and mean blood pressures, in pulmonary capillary wedge pressure, in cardiac index and in stroke index were observed during period 2, whereas heart rate, right atrial pressure and systemic vascular resistances were unaffected. The greater the size of the tumour and the difficulties in dissection, the greater were these intraoperative haemodynamic changes. In addition, the pulmonary arterial blood temperature and the noradrenaline plasma concentrations (double isotope enzymatic assay) increased significantly during period 2. In conclusion, the prolonged microsurgical technique of acoustic tumour dissection through the retrosigmoid approach may modify left ventricular loading conditions and may lead to pulmonary oedema, even if intravascular volume expansion was minimal and ventricular function was near normal.

[Is osteosynthesis justified for spinal injuries in children?].

The legitimacy of osteosynthesis for the treatment of spinal injuries in children is analyzed as a function of results in 10 cases, 7 affecting the cervical, 2 the thoracic and one the lumbar region, six of the children being under 10 years of age. Five of these children had serious neurologic disorders, including 4 with high tetraplegia. Technical difficulties of osteosynthesis were not made easier by the poorly adapted nature of the material for infantile statures. Indications for this surgery were not only those cases not improved by orthopedic therapy: instability of lesions, the child's condition and deterioration in the neurologic state can also require initial treatment by osteosynthesis. The principal complication is postoperative cervical kyphosis, but this can be prevented by early active reeducation, the stability of the fixation dispensing with the need for external contention.

[Acute hydrocephalus in tuberculous meningitis in adults].

The authors report a case of tuberculous meningitis in a young man who developed acute hydrocephalus as soon as the fifteenth day of the course of the disease. Attention is drawn to the importance of computerized tomography in investigating sudden deterioration in patients with tuberculous meningitis. Emphasis is put on the value of a shunt procedure which, in the case reported here, led to immediate improvement before antituberculous chemotherapy could have been effective.

[Localized fast rhythms in EEG tracings following surgery for intracranial meningioma].

Forty-six patients were followed up after removal of an intracranial meningioma. Nine of the 46 patients in their 3rd month postoperative EEG had localised fast rhythms which remained stable. The fast rhythms appeared in small 20-25 Hz and 20-40 microV bursts; they were localised over the craniotomy flap as shown by the control X-ray of the sites of the electrodes; they were unaffected by eye-opening and slightly reduced by fist-clenching. These fast rhythms were sometimes mixed with sharp waves and theta activity and seemed to be equivalent to the 'breach rhythm' described first by Fischgold et al. (1952) and then by Cobb et al. (1979). In our study, these rhythms were more frequently observed in patients with an olfactory or sphenoidal meningioma, in patients with pre-operative seizure and in patients with an extensive post-operative intracranial atrophy (as shown by the scanner). On the other hand, incomplete removal or recurrence of the tumour or post-operative epilepsy did not seem to play a role in the appearance of these rhythms.

[Use of stereotaxic neurosurgery in the treatment of pain in cervicofacial cancers].

Mesencephalic tractotomy employing the stereotaxic method was conducted 12 times in 11 patients with pain due to cervicofacial cancer only partially relieved by high doses of opiates. Immediate results were spectacular in 10 cases and partial on the other 2 occasions. However, relief was not permanent even in patients in whom the greatest improvement was obtained, and the usual analgesics had to be prescribed after 3 months. The operation, which requires only a short period of anesthesia, was always well supported, complications being anesthesia of one side of the body in 2 patients and convergence paralysis in two cases, one of which was transient. Mesencephalic tractotomy constitutes a new weapon for the treatment of diffuse cervicofacial cancer pain not responding to major medical treatment. Elective thermocoagulation of the Vth and IXth nerves was also successfully employed for systematized pains.

[Contribution of arteriography to the investigation of peripheral nerve tumours (author's transl)].

Based on their personal experience of the use of arteriography in 11 patients, the authors describe the angiographic appearances of both benign and malignant peripheral nerve tumours. They emphasise the reasons for errors, and the criteria enabling the precise nature of the lesion to be determined pre-operatively in the majority of cases. Other contributions supplied by angiography are discussed.

[Surgical management of primary peripheral nerve tumours (author's transl)].

A rational approach to the surgical treatment of peripheral nerve tumours can be determined by a knowledge of current concepts concerning their pathology and by clinical and arteriographic preoperative findings, and guided by extemporaneous histological examination results. It can be modified by the presence of metastases or associated phakomatosis.

[Intraneural synovial cyst in the peroneal nerve. Case report (author's transl)].

The authors report one case of paralysis of the peroneal nerve due to an intraneural synovial cyst, in connection with the superior tibio-fibular joint. After an anatomic work and a complete revue of the literature, etiopathogenic and diagnostic problems seem to be resolved, and this justifies their terminologic choice.

[Malformations of the spino-cervical joint and of the cervical spine associated with Binder's syndrome (author's transl)].

The authors found in 53.5% of the cases of Binder's Syndrome, where a radiological work up had been carried out on the cervical spine and the spino-cervical joint, malformations of varying importance in these related structures. This lesional association had not as yet been pointed out. After pathological groupings and an analytical study of the anomalies encountered, the question of a common inducer factor is raised, or at least a factor contemporary to the two dysplasias, maxillo-nasal and vertebral. In practical terms, it would seem vital that all individuals with Binder's syndrome have a radiological examination of the cervical spine and the spino-cervical joint. In those subjects presenting with malformations and in particular, complex corporeal dysplasias, the authors strongly insist on the necessity of regular follow up in order to make an early diagnosis of eventual neurological repercussion.

[Clinical and radiological aspects of maxillo-nasal dysostosis: "naso-maxillo-vertebral syndrome". A study of 34 new cases (author's transl)].

Maxillo-nasal dysostosis is not uncommon as we have noted 34 new cases in eight years. The most characteristic anomalies, well described by Binder, are nasal hypoplasia both of bone and cartilage with agenesis of the nasal spine, as well as a characteristic rearrangement of the naso-labial muscles. On first seeing the patient the disease is generally recognized by the very typical aspect of the nose. There very often exists however other dental, mandibular and cervical spine anomolies. It is indispensable to look for these anomalies in the work up of patients with this malformation syndrome "the naso-maxillo-vertebral syndrome", in order to better understand the disease and better treat the patients.

[Treatment of Binder's maxillonasal dysostosis (author's transl)].

The treatment of Binder's maxillonasal dysostosis raises many problems and difficulties of both orthodontic and surgical natures. Orthodontic therapy should be conducted as early as possible and include, principally, an advancement of the maxilla by heavy extra-oral postero-anterior traction on an orthodontic mask. If good occlusion is obtained the patient can then be treated to improve the anatomical conditions of the muscles of the nose and upper lip. Maxillary, and more rarely mandibular osteotomies are indicated in cases with poor occlusion. When occlusion is reasonably good the hypoplasia has to be compensated for by using large portions of ilac bone to reconstruct the ridge and point of the nose. A preseptal graft on the ridge and secondarily, revisions of the point of the nose are often essential to ensure the best results.

[External morphology of the roe deet (Capreolus capreolus L)].

The results of a morphological study of the cerebellum of the roe-deer are given. The structural simplicity of Lobus Rostralis, the relatively small development of Lobulus Ansiformis fully agree with previous works on the pattern of the cerebellum in Ungalata.

[The azygos system].

The great variety of anatomical dispositions of the azygos system explains its facility of adaptation. The second lumbar vein is able to play a buffer role between the caval systems or, conversely, is able to direct venous flow to a preferential system. In case of portal hypertension, an inferior omphalo-azygos flow by the right ascending lumbar vein was noticed. Finally, the left venous system may either be the major element of the azygos system (mainly by a big ascending lumbar vein) or be divided in 2 distinct streams to the azygos venous trunc. The final disposition of the azygos system seems to correlate well with a progressive evolution towards an unique trunc, linking directly the two caval systems (this being confirmed by foetal data). Practically, the study of the arterial and venous relations of the azygos crossing have interesting applications in surgery.
