CYSTIC BRAIN LESIONS: AN EXPERIENCE OF THE STEREOTACTIC TECHNIQUE USE IN SURGERY

The aim of this study was the analysis of 24 cases when navigation system Stealth Station® TREON®Plus Medtronis (USA) and stereotactic system Zamorano-Dujovny were used in the treatment of brain lesions with cystic component.

The patients were distributed according to localization of tumors: corpus callosum — 1 patient, the medial parts of the frontal lobe — 5, thalamus — 6, occipital lobe — 1, temporal lobe — 5, sellar area — 3, third ventricle — 3.

Materials and methods. There were 15 men and 9 women. The age of patients ranged from 22 to 68 years. Karnavskyy score before surgery ranged from 50 to 90 points (average 76,4±4,5). Tumor size ranged from 2.8 to 4 cm in greatest size (mean 3.55±0.70 cm). A comprehensive preoperative examination included ophthalmological and neurological examination, CT and MRI of the brain. MRI was performed in 10 cases, the MR-scanner Magnetom P8 (Siemens) with a voltage of 0.2 T magnetic field. In all cases, amplification was performed intravenously by magnevist or tomovist.

Conclusions: in general, all patients who performed stereotactic treatment of cystic neoplasms discharged with improvement of neurological, cerebral state index and the average Karnavskyy (from 63 points to 71 points). Histological diagnosis verification was not received in 1 case.
