[Video endoscopy in neurosurgery].

The authors present an analysis of their experiences with performing more than 330 video endoscopic operations on the autopsy material and in 172 patients. In 54 of these patients operations were performed for traumatic intracranial convex hematomas, in 21 for adenomas of the hypophysis, in 14--for arterial aneurysms, and 53 patients with discogenic radiculitis, spinal tumors, consequences of severe spinal traumas. In 25 patients the endoscopic videomonitoring was made during excision of the tumors, paratumorous cysts and abscesses of the brain, decompression of the optic nerve, plasty of the anterior cranial fossa fundus with closing the liquor fistulas. Intraoperative angioscopy in carotid endarterectomy was fulfilled in 5 patients. The video endoscopy was proved to result in less traumaticity of the radical surgery. It is a valuable and highly informative method giving optimum results in performing many microsurgical operations.

[The combined use of intraoperative video endoscopy and contact microvascular dopplerography in the surgery of cerebral aneurysms].

The article describes results of an anatomo-clinical investigation using video-endoscopy and contact microvascular dopplerography in surgery of cerebral aneurysms. The endoscopic anatomy of cisterns of the cerebral base was studied in 36 corpses of adult humans. More than 200 video-endoscopic operative interventions were performed on sectional material. Video-endoscopy in combination with contact microvascular dopplerography was conducted in the clinic on 20 patients with aneurysms of the brain. Main advantages of endoscopy used in combination with microvascular dopplerography during clipping the aneurysm are formulated. Complex using the two methods described gives less volume of the access and traumaticity of the intervention but not less radical effect. It is a valuable and highly informative method which optimizes performing the operation and has less amount of postoperative complications.

[Transsphenoidal surgery for large and giant pituitary adenomas by intraoperative video endomonitoring].

The paper analyzes the outcomes of surgical treatment of patients with pituitary adenomas on the basis of 614 performed transsphenoidal surgical appliances, of which there were 209 large and giant pituitary adenomas. The use of intraoperative video endomonitoring during these interventions could substantially reduced the number of complications, enhance the radicalism and selectivity of a surgical appliance. By using such advantages as endoscopy as powerful lighting, an endomicroscopic phenomenon, and a lateral view, at surgery we could precisely determine the borders of an adenoma, the site and sizes of non-removed tumors fragments. The lateral view of an endoscope permits removal of a tumor via the optimal access, prevention of traumatization of cerebral structures and the contents of cavernous sinuses. If there is intraoperative liquorrhea, the latter can be verified and eliminated. Thus, the accumulated experience allows the authors to recommend using intraoperative video endomonitoring during transsphenoidal surgery for pituitary adenomas.
