PURPOSE This article is the first prospective documentation of the efficacy and safety of gamma knife surgery (GKS) in the treatment of drug-resistant epilepsies of mesial temporal lobe origin. METHODS From July 1996 to March 2000, three European centers selected 21 patients with mesial temporal lobe epilepsy (MTLE) for a temporal lobectomy. The(More)
PURPOSE To better predict permanent complications from arteriovenous malformation (AVM) radiosurgery. METHODS AND MATERIALS Data from 85 AVM patients who developed symptomatic complications following gamma knife radiosurgery and 337 control patients with no complications were evaluated as part of a multi-institutional study. Of the 85 patients with(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)
¶ 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%)(More)
PURPOSE To determine the efficacy of gamma knife radiosurgery in the treatment of mesial temporal lobe epilepsy due to mesial temporal sclerosis. METHODS Between November 1995 and May 1999, 14 patients underwent radiosurgical entorhinoamygdalohippocampectomy with a marginal dose of 18, 20, or 25 Gy to the 50% isodose following a standard preoperative(More)
Stereotactic radiosurgery (SRS) using the Leksell gamma knife promotes acute and chronic local changes in glucose metabolism. We have been able to find very few papers on Medline on the subject of assessment of metastases by 2-[18F]fluoro-2-deoxy-D-glucose positron emission tomography (FDG PET) after SRS. The aim of this work was to specify the additional(More)
Background. The goal of nonsecreting pituitary adenoma radiosurgery is to halt tumour growth and to maintain normal performance of the hypophysis and the functionally important structures around the sella. The effectiveness of gamma knife radiosurgery was evaluated. Method. Over a period of 10 years (1993–2003), 140 patients with nonsecreting pituitary(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)
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. Between 1992 and 2001, we treated 351 patients with a vestibular schwannoma by GKS, control of(More)
 For 6 years (1992–1998) we have treated 67 patients with cavernous sinus meningioma using the Leksell gamma knife in the Hospital Na Homolce, Prague. The age of the patients ranged between 19–82 years, median 57 years. Radiosurgery was the primary treatment in 64,2% of the patients, in the rest a microsurgical resection preceded. The volume of the tumour(More)
