Abstract
Between March 1992 and January 1998, 100 stereotactic procedures were carried out in our Stereotactic Department. Of these, 24 were performed on patients under 18 years of age, 22 of them under a local anaesthetic and sedation. The ages of these patients ranged between 4 months and 18 years. The stereotactic procedures carried out were: 15 cerebral biopsies, 5 iodine-125 implants, 4 implantations of Rickham reservoirs with ventricular catheter, with additional holes to establish a connection between the cyst content and the ventricular system (internal drainage): 2 of these patients had arachnoidal cysts in the pineal region, 1 a thalamic neuroepithelial cyst and 1 a cystic craniopharyngioma, with excellent control of hydrocephalus. All cerebral biopsies were positive, including 3 in which brain stem tumours were detected. Of the 5 patients treated by brachytherapy, 4 had pilocytic astrocytomas and 1 an anaplastic astrocytoma. The sites of the tumours for which implants were used were the thalamus in 4 cases, and the basal ganglia (corpus striatum) in 1. In only 2 cases was there some transistory morbidity, and mortality was nil. The stereotactic procedures in this varied group were well tolerated, with low morbidity and mortality rates, which proves that this method is effective and safe for patients. It can also be used for the diagnosis of brain stem tumours. Midline cysts can also be treated by means of internal drainage with catheters (a minimally invasive form of surgery).
