Functional magnetic resonance imaging (fMRI) was performed in patients with Parkinson's disease during deep brain stimulation of the subthalamic nucleus (three patients) and during deep brain stimulation of the ventral intermedius nucleus of the thalamus (one patient). All showed an increase in blood oxygenation level-dependent signal in the subcortical(More)
OBJECT Meningioma is the most frequent benign tumor treated with Gamma Knife surgery (GKS); however, the assessment of its efficacy and safety in slow-growing tumors is an ongoing process, requiring analysis of long-term results. METHODS Three hundred sixty-eight patients harboring 400 meningiomas treated between 1992 and 1999 at Na Homolce Hospital were(More)
Meningiomas are the most frequent benign tumors treated by gamma knife radiosurgery and the majority of them are located on the skull base. Between 1992 and 1999, 197 skull base-located meningiomas in 192 patients were treated by gamma knife in Prague. Contact with the chiasma or optic tract was not regarded as a contraindication for gamma knife(More)
OBJECTIVE Although relevant information exists regarding the chance of obliterating arteriovenous malformations (AVMs) using radiosurgery, the overall chance of cure after gamma knife radiosurgery is usually only extrapolated from a portion of all monitored patients. This chance and the risks involved in radiosurgery, including repeat treatment when(More)
OBJECT The authors present the long-term follow-up results (minimum 5 years) of patients with essential trigeminal neuralgia (TN) who were treated with gamma knife surgery (GKS). METHODS One hundred seven patients (61 females and 46 males) underwent GKS. The median follow up was time was 60 months (range 12-96 months). The target was the trigeminal root,(More)
PURPOSE When gamma knife radiosurgery (GKS) does not achieve control of the growth of a tumour, the need to repeat treatment is considered. The results and risks of repeat treatment of patients with a vestibular schwannoma were reviewed to assess its efficacy and safety. METHODS Between 1992 and 2001, we treated 351 patients with a vestibular schwannoma(More)
PURPOSE Minimally invasive percutaneous single trajectory stereotactic radiofrequency amygdalohippocampectomy was used to treat mesial temporal lobe epilepsy (MTLE). The aim of the study was to evaluate complications and effectiveness of this procedure. MATERIALS AND METHODS A group of 51 patients with MTLE was treated using stereotactic thermo-lesion of(More)
Between October 1995 and October 1996, we treated 49 patients suffering from trigeminal neuralgia with Gamma Knife radiosurgery. There were 23 males and 26 females. The mean age was 68 (range 38-94 years) The root of the trigeminal nerve close to brain stem was chosen as the target. The maximum dose was 70 Gy in 24 cases and 80 Gy in 25 cases. A single shot(More)
Leksell Gamma Knife was used to treat 66 patients with glomus jugulare tumour at 6 European sites between 1992-1998. The age of the patients ranged between 18-80 years (median 54 years). Gamma Knife radiosurgery was a primary treatment in 30 patients (45. 5%). Open surgery preceded radiosurgery in 24 patients (36.4%), embolisation in 14 patients (21.2%) and(More)
BACKGROUND To review our experience with morphological developments during the long-term follow-up of patients treated by Gamma Knife radiosurgery for mesial temporal lobe epilepsy. METHOD Between 1995 and 1999, we treated 14 patients with marginal doses of 24 Gy (n = 6) and 18-20 Gy (n = 8). Nine of these were operated on for insufficient seizure(More)
