The authors analyzed of the long-term complications that occur 2 or more years after gamma knife surgery (GKS) for intracranial arteriovenous malformations (AVMs).Patients with previously untreated AVMs were managed by GKS and followed at least treatment selected analysis (237 cases). Complete AVM obliteration was attained in 130 cases (54.9%), incomplete 107 (45.1%). Long-term observed 22 patients (9.3%). These included hemorrhage (eight cases), delayed cyst formation increase seizure...
The objective of the present study was an evaluation incidence and risk factors for erroneous histopathological diagnosis low-grade glioma after stereotactic biopsy. Twenty-eight tumors diagnosed as biopsy surgically resected thereafter were analyzed. There 13 astrocytomas, 7 oligodendrogliomas, 8 mixed gliomas. All neoplasms had a lobar location. Seven contrast enhancement on MRI. number tissue samples obtained during one in 19 cases, two 4, three or more 5. Complete diagnostic agreement...
OBJECT There is no standard therapeutic strategy for low-grade glioma (LGG). The authors hypothesized that adjuvant therapy might not be necessary LGG cases in which total radiological resection was achieved. Accordingly, they established a treatment based on the extent of (EOR) and MIB-1 index: patients with high EOR low index were observed without postoperative treatment, whereas those and/or received radiotherapy (RT) chemotherapy. In present retrospective study, reviewed clinical data...
The objective in the present study was to evaluate usefulness of cortico-cortical evoked potentials (CCEP) monitoring for intraoperative assessment speech function during resection brain tumors.Intraoperative CCEP applied 13 patients (mean age 34 ± 14 years) removal neoplasms located within or close language-related structures dominant cerebral hemisphere. For this purpose strip electrodes were positioned above frontal language area (FLA) and temporal (TLA), which identified with direct...
OBJECTIVE: Evaluation of results the neurofiberscopic biopsy tumors pineal region and posterior third ventricle. METHODS: From 2001 to 2004, 23 patients (mean age, 30.6 yr) with located in or ventricle underwent simultaneous ventriculostomy. The procedure was indicated for verification histological diagnosis neoplasm, which planned be treated by radiotherapy and/or chemotherapy without open surgery (eight patients), establishment pathological further choice most appropriate treatment...
Object. The authors analyzed of the long-term complications that occur 2 or more years after gamma knife surgery (GKS) for intracranial arteriovenous malformations (AVMs). Methods. Patients with previously untreated AVMs were managed by GKS and followed at least treatment selected analysis (237 cases). Complete AVM obliteration was attained in 130 cases (54.9%), incomplete 107 (45.1%). Long-term observed 22 patients (9.3%). These included hemorrhage (eight cases), delayed cyst formation...
Object. The purpose of this study was to evaluate an original neurofiberscope-guided strategy for the management slit-ventricle syndrome that occurs after shunt placement. Methods. Between 1995 and 2003 15 patients with (mean age 14.2 years) underwent endoscopic third ventriculostomy (ETV) removal. During initial surgical procedure a neurofiberscope small outer diameter inserted along tube into collapsed ventricle endoscopically controlled removal ventricular catheter evaluation brain...
Optimal management of cavernous sinus hemangiomas remains unclear. Total microsurgical removal these neoplasms may be extremely difficult due to their rich vascularization. Three cases hemangioma treated with low-dose Gamma Knife radiosurgery are presented. Marginal dose varied from 10 13 Gy. Treatment planning and radiation dosimetry were done a goal conformal selective coverage the lesion 50% prescription isodose line using multiisocenter technique. In all significant shrinkage neoplasm...
Abstract The optimal technique of microvascular decompression (MVD) for trigeminal neuralgia (TN) caused by venous conflict remains unclear. objectives this study are to characterize the offending veins identified during MVD TN and evaluate intraoperative applied their management. From 2007 till 2019, 308 surgeries were performed in 288 consecutive patients with TN, 58 them, pure was identified. In 44 patients, vein interrupted, as done small arising from cisternal nerve (CN V) or its root...
<i>Rationale:</i> Two or three decades ago, cancer pain was treated by surgical/chemical hypophysectomy. In one report, the control of central (thalamic syndrome) also approached with chemical Although in most patients these treatments resulted a decrease severe pain, concomitantly adverse effects (panhypopituitarism, diabetes insipidus and visual dysfunction) occurred patients. This historical evidence prompted us to perform Gamma Knife surgery (GKS) for this kind intractable...
Object. The authors have treated intractable pain, particularly cancer pain related to bone metastasis, with various protocols. Cancer has been by gamma knife radiosurgery (GKS), targeted the pituitary gland—stalk, as an alternative new control method. purpose of this study was investigate a prospective multicenter protocol prove efficacy and safety treatment. Methods. Indications for patient inclusion in treatment were: 1) metastasis; 2) no other effective options; 3) general condition...
