Treatment of brain deep lesions by stereotaxy / 医学研究生学报

ABSTRACT

Objectives:To discuss the effects of stereotactic techniques in treating brain deep lesions. 　Methods: Eighty-two patients with deep brain lesions were treated by fisher stereotactic apparatus and ASA-601S. Among these, stereotactic biopsy was performed in 22, clearance of haematoma in 5 (2 located in brain stem), aspiration of brain abscess in 2 and placement of Ommaya tube into cystic craniopharyngioma in 53.　Results: All of the 22 biopsies were pathologically diagnosed, which included 10 cases of glioma, 4 cases of germ cell tumor, 3 cases of brain parasite, 4 cases of metastatic lung tumor and one case of hyperplasia of colloid cells at rear end of third ventricle, which turned to be glioma in follow-up period. Tumor resection was performed in 4 patients with glioma and radiation therapy for other tumors. After the treatment, 6 patients were fully recovered ( 4 with germ cell tumor and 2 with metastatec tumor). All brain parasite, brain abscess and brain haematoma were cured. Three patients with craniopharyngioma were cured after the placement of Ommaya tube (with radiation therapy inside the cyst), and others were improved. 　Conclusions:Stereotaxy has the advantages of precise location, less damage, easy manipulation and on the safe side. It is worth advocating.
