RESUMO
OBJECTIVE: To evaluate the efficacy of surgery in reducing neurological symptoms in patients with focal brain tuberculosis. MATERIAL AND METHODS: Seventy-four patients with tuberculosis meningoencephalitis were studied. Among them, 20 people with a life expectancy of at least 6 months were identified, in whom foci with a ring-shaped accumulation of contrast along the periphery were determined during MSCT of the brain. Formed tuberculomas and abscesses were removed from 7 patients (group 1) under neuronavigation control. Indications for the operation were: the absence of a reduction in size for 3-4 months, the limitation of the lesion to 1-2 foci with reduction of perifocal edema according to MSCT and normalization of cerebrospinal fluid. Six patients had contraindications or refusals from operations (group 2). In 7 patients, there was a decrease in formations by the control period (group 3). Neurological symptoms in the groups at the beginning of the observation were similar. The duration of observation was 6-8 months. RESULTS: In group 1, patients were discharged with improvement, postoperative cysts were determined in all of them at discharge. In group 2, 67% died. In group 3, 43% of patients had a complete reduction of foci during conservative treatment, in 57% cysts formed in place of foci. Neurological symptoms decreased in all groups, with the most decrease in group 1. However, statistical analysis did not show significant differences between the groups regarding the reduction of neurological symptoms. A significant difference in the mortality criterion between groups 1 and 2 was obtained. CONCLUSION: Despite the absence of a significant effect on the reduction of neurological symptoms, the high survival rate of operated patients shows the need to remove tuberculosis formations in all the cases.
