INTRODUCTION: Decompressive hemicraniectomy in large hemispheric infarctions has been reported to lower mortality and improve the unfavorable outcomes. Hematoma volume is a powerful predictor of 30-day mortality in patients with intracerebral hemorrhage (ICH). Hematoma volume adds to intracranial volume and may lead to life-threatening elevation of intracranial pressure. METHODS: Records ...

BACKGROUND: Oncological treatment of a neoplasm is more than surgical removal of the tumor. Probably, this truth is the reason for the ongoing discussion on cavernous sinus meningiomas in the last decade. Debate on optimal management of cavernous sinus meningiomas aims to compare the different treatment strategies: (a) radical surgical ...

Spinal meningiomas are usually benign, slow-growing tumours and are commonly associated with good patient outcome following surgery. However, the existence of a severe preoperative neurological deficit has been considered to be a possible predictor of poor functional outcome after surgery. We retrospectively reviewed data from 33 patients with 35 spinal ...

There are relatively few reports detailing the outcome of children and adolescents with arteriovenous malformations (AVMs) treated with stereotactic radiosurgery (SRS). We reviewed our experience over the past decade to determine whether the outcomes and toxicity were similar to those reported in adults. Seventeen patients 18 years of age or ...
Veznedaroglu Erol - - 2004
OBJECTIVE: Despite the success of stereotactic radiosurgery, large inoperable arteriovenous malformations (AVMs) of 14 cm(3) or more have remained largely refractory to stereotactic radiosurgery, with much lower obliteration rates. We review treatment of large AVMs either previously untreated or partially obliterated by embolization with fractionated stereotactic radiotherapy (FSR) regimens using ...

OBJECT: Stereotactic evacuation of hematoma has been reported to reduce the incidence of mortality and to improve functional outcome in patients with spontaneous putaminal hemorrhage. Stereotactic evacuation of hematoma has not been widely accepted as a standard therapy, however, because its effect on functional outcome has been regarded as marginal ...
Schneck Michael J - - 2004
Objective: We sought to identify predictors of death or discharge to home for patients with nontraumatic subdural hematoma (NT-SDH). Background: Because neurologists are often involved in evaluation of patients with NT-SDH, we sought to identify factors that would be important in guiding patients and families about outcomes after diagnosis (and ...
