[Preoperative embolization of the internal carotid artery in surgical treatment of meningioma in the base of the anterior and middle cranial fossae].

Preoperative embolization is a widely used technique that may decrease blood supply to rich-vascurized tumors of the brain. Its use allows a neurosurgeon to safely remove a tumor of different histological nature and site. The objects of preoperative embolization are most commonly meningiomas at convexital or parasagittal sites.

[Anastomoses between the meningeal arteries and the cavernous sinus: the clinical picture, diagnosis and treatment].

The findings of 106 patients with arteriosinus anastomoses formed by the meningeal arteries and cavernous sinus were analyzed. The clinical symptoms, the specific features of the course of this abnormality and the principle of its diagnosis are summarized. Based on angiographic data, 4 types of anastomoses were identified by X-ray and anatomic signs: 1) the anastomoses formed by the meningeal branches of the internal carotid and cavernous sinus (45.

[The visual functions of patients with traumatic carotid-cavernous anastomoses].

The visual functions in 100 patients with traumatic carotid-cavernous anastomoses were studied. In 54% of cases the visual functions were impaired, in 33% they were lost to various degrees, 21% of patients were practically blind. The most frequent cause of disorders of visual functions were hemodynamic changes in the optic nerve and retina, a less frequent cause was traumatic damage to the optic nerve in its canal.

[The effect of YAG laser capsulotomy on the hydro- and hemodynamics of the eye].

Tonographic studies of 18 patients with artiphakia and aphakia and rheo-ophthalmographic examinations of 36 patients with artiphakia after YAG laser discission of opaque posterior capsule of the lens have revealed significant impairment of ocular hydrodynamics, most manifest in the first hours postoperation, persisting for 24 hrs on an average. In patients, whose rheographic values were within the normal age-specific range, a marked RQ reduction 3-4 hrs postoperation was observed, still present in 24 hrs. No changes in the ocular hemodynamics were detectable in patients with initially lowered rheographic coefficient.
