Abstract:
Objective To explore the methods, efficacy and advantages ofstereotactic surgery.Methods A retrospective analysis of 29 consecutive patients with 37 lesions (mean age, 34.6 years),received surgery between Dec 2002 and Nov 2009, was performed. Histological findings showed 11 craniopharyngiomas, 5 cystic gliomas, 3 metastases and 10 cerebral abscesses. Eighteen patients underwent cyst aspiration by the Ommaya reservoir system combined with 32P endocavitary irradiation;median irradiation doses were 800 μCi. One was treated with aspiration and then radiotherapy only. Ten patients with cerebral abscesses received cystic drainage (8 cases) and aspiration (2 cases). Results No operative bleeding and death were found in this experiment. Follow up was performed for a median of 10.6 months (range, 1-60 months) and 4 were out of contact. All patients with craniopharyngiomas remained stable without recurrence after treatment; complete resolution was achieved in all patients with cerebral abscess; in the other 8 patients with tumors(12 lesions), 5 were under control of the symptoms for an average of 14 months and 3 (2 with metastases and 1 with glioblastoma) did not get improvement after the treatment. Two patients with craniopharyngioma experienced a transient slightly worsening of hypothalamic functions, including transient diabetes insipidus, low fever and vomit. Conclusion Stereotactic technique has its advantages in treating patients with cerebral abscess, craniopharyngiomas,metastatic tumors and gliomas that were small size, while it does not that effective in the cystic metastases that are in large size and difficult to control in a short term.
