Endofiberscopic intracranial stereotopography and endofiberscopic neurosurgery.

The possibilities of endoscopic operative procedures in preformed and artificial intracranial and intracerebral cavities are described. Endoscopic investigations were carried out on 166 cadavers; death was due to extracranial pathology and severe brain injury. 132 patients with intracranial lesions were operated on endoscopically. An extended description of endofiberscopic intracranial topographical relationships and endofiberscopic neurosurgical approaches is given. Endoscopic stereotopography of more than 130 intracranial structures is studied.

[Experience using intracranial endoscopy in neurologic traumatology].

The endoscopic anatomy of the subdural space structure and endoscopic semiotics of intracranial lesions are presented. The direct vision of the lesion substrate outside projection of a small trepanation opening raised the reliability of diagnosis, provides a wide and atraumatic access for the removal of spreaded hematomas and other foci, allows surgery to be fulfilled even in critical patients. The application of intracranial endoscopy in neurotraumatology is considered as a technical principle.

[Echotomography of the posterior cranial fossa].

The use of ultrasound tomography for the study of the posterior cranial fossa through intact bones of the skull permits to detect the contour of the cerebellar hemispheres. A scanning of the operational defect of the occipial bone allows one to determine the echotographical structure of the posterior cranial fossa and the adjacent area in a 2 plane picture which is easily correlated with the anatomical sawing of the head in the same plane. It was also possible to eliminate the contours of a recurrent cystous tumour of the cerebellum. The clinical results are correlated with the data of autopsies in experimental studies. The authors are of the opinion that the method of echoencephalotomography during surgical operations of the posterior cranial fossa is quite perspective.

[Two-dimensional echoencephalography through a trepan defect in the skull].

With the aid of a non-adapted equipment echoencephalotomogrammes were obtained that revealed fine details of intracranial structures in normals and in patients with space-occupying lesions, these tomogrammes being comparable to those obtained after anatomic sections of the skull in the same planes. This becomes possible thanks to the absence of the bone as a limiting factor. Interpreting the conducted examinations as a model of intraoperative scanning, and considering the results of experimental craniotomies, a conclusion is made as the importance of such investigations especially in cases of bilateral space-occupying lesions.

[Endoscopic anatomy of the superior petrosal vein].

The structural topographic features of a constantly present surgically significant formation--the superior petrosal vein--were disclosed on the basis of postmortem examination of the region of the cerebellopontile angle (204 cases) by means of fine endofibroscopes introduced through a small trephination opening behind the mastoid process of the temporal bone. The method provides for detailed appraisal of the microtopography of the vessel in three-dimensional space without disturbing the regional structural relationships, and makes it possible to disclose more exactly the character of the connection of the vein with the meninges and to determine the variants of the topography of its orifice and the types of formation of the main venous collector without damaging this easily injured vessel. The surgical significance of the recorded features of the structure of the superior petrosal vein is shown.
