PURPOSE Age above 65 years is a strong negative prognostic factor for survival in patients with malignant gliomas (MG) treated with radiotherapy (RT) and its value has been questioned. We analyzed the effect of RT on the survival of elderly patients with malignant gliomas. METHODS AND MATERIALS We examined 85 consecutive elderly patients with a(More)
Neuroendoscopic procedures are increasing in frequency in neurosurgical practice. We describe the anesthetic technique and the perioperative complications found in 100 neuroendoscopic interventions performed at our institution. Cranial tumor biopsy or retrieval (62%) and cisternostomy for hydrocephalus (33%) were the most frequent indications for(More)
Intermittent high peak pressure values inside the endoscope during neuroendoscopic surgical procedures are associated with postoperative morbidity. Unexpected delay in awakening is the complication most frequently observed by the anesthesiologist as a result of high peak pressure values inside the endoscope. During eight neuroendoscopic procedures the(More)
BACKGROUND The clinical outcome of glioblastoma (GBM) patients who receive radiotherapy alone or with chemotherapy is well established. However, little is known about how many patients do not receive this treatment. We consider it is important to investigate why a proportion of operated patients do not receive further treatment after surgery. METHODS We(More)
Normal saline solution is currently used as the ventricular irrigation fluid during neuroendoscopic procedures. The aim of this study is to determine the alterations in the cerebrospinal fluid (CSF) composition after neuroendoscopic interventions. Twenty nine patients who underwent a neuroendoscopic procedure under general anaesthesia were studied.(More)
BACKGROUND AND PURPOSE Whereas fMRI postprocessing tools used in research are accurate but unwieldy, those used for clinical practice are user-friendly but are less accurate. We aimed to determine whether commercial software for fMRI postprocessing is accurate enough for clinical practice. METHODS Ten volunteers underwent fMRI while performing motor and(More)
OBJECTIVE The authors' objective is to report the initial appreciations on the use of the intraoperative near-infrared indocyanine green videoangiography during aneurysm surgery in our center. METHOD 10 surgical procedures have been made in 9 patients, 5 males and 4 females between 27 and 61 years old with an average of age of 49 years during a time of 10(More)
OBJECTIVE The aim of this study was to describe monitoring, anesthetic management, and risk factors for complications in neuroendoscopic surgery. PATIENTS AND METHODS Patients who underwent neuroendoscopy between 1994 and 2003 under general anesthesia, with monitoring of intracranial pressure from inside the neuroendoscope, were studied retrospectively.(More)
BACKGROUND Malignant gliomas are tumors of bad prognosis with a mean survival of 12 months. In the present report 74 patients diagnosed of malignant glioma were studied with the following aims: 1) evaluate how many could receive combined radiotherapy (RT) and chemotherapy (BCNU) treatment following surgery and 2) analyze whether the patients treated(More)
