BACKGROUND AND PURPOSE We sought to describe the clinical outcome and results obtained in the endovascular therapy of ruptured cerebral aneurysms in the elderly over an 8-year period. We compared endovascular therapy results in patients aged > or =65 and <65 years. METHODS During 1993-1999, 52 patients aged 65 to 85 years (mean age, 71.5+/-4.7 years) were(More)
Neuroepithelial dysembryoplastic tumor (DNT) is usually considered as a supratentorial benign neoplasm. DNT of the posterior fossa is a very rare entity and only four previous cases were reported in the literature. We describe a case of a 26-Year-old woman presenting recurrent episodes of vertigo. Magnetic resonance imaging revealed four cystic lesions(More)
The aim of this study was to assess the safety and efficacy of intraventricular fibrinolysis (IVF) for aneurysmal subarachnoid hemorrhage (aSAH) with severe intraventricular hemorrhage (IVH). In this randomized controlled trial, between 2005 and 2009, patients with aSAH and severe IVH were randomly assigned into two groups: one treated with external(More)
We propose a dynamic model of cerebrospinal fluid and intracranial pressure regulation. In this model, we investigate the coupling of biological parameters with a 3-D model, to improve the behavior of the brain in surgical simulators. The model was assessed by comparing the simulated ventricular enlargement with a patient case study of communicating(More)
STUDY DESIGN Retrospective review of prospectively collected data. BACKGROUND There is no consensus regarding the ideal treatment of thoraco-lumbar spine fractures without neurological compromise. Many surgical techniques have been described but none has proved its definite superiority. The main drawback of these procedures is directly related to the(More)
Two cases of Brown-Sequard syndrome following a stab wound of the cervical spinal cord are reported. Spinal cord hemisection was confirmed by magnetic resonance imaging and surgical exploration. Both patients presented leakage of the cerebrospinal fluid and underwent surgical repair. In the first case, the pia-mater was sutured to close the wound and(More)
INTRODUCTION Cervical discectomy with interbody fusion is a common procedure in spinal surgery. The resultant biomechanical alterations accelerate degeneration of the adjacent segment, but the contribution of natural degeneration to adjacent segment disease is unclear. OBJECTIVE To assess the long-term rate of surgery to discs adjacent to cervical(More)
Single-use surgical instruments were recently introduced to improve OR efficiency and reduce infection risks. This study aimed to investigate clinical results 1 year after instrumented lumbar fusion, with the aid of single-use surgical instruments, with particular attention to surgical site infection and Oswestry Disability Index (ODI). This prospective(More)
Controlled trials have shown that total disc replacement (TDR) can provide pain and disability relief to patients with degenerative disc disease; however, whether these outcomes can also be achieved for patients treated in normal surgical practice has not been well documented. This prospective, international study observed changes in disability and back(More)
During the past years, the development of new technologies and techniques has been applied to brain tumor surgery, leading to decreased surgical morbidity and increased efficiency. These techniques can be used to reduce the invasiveness of the surgical approach (endoscopy, neuronavigation, robotics), to improve guidance (stereotaxy, neuronavigation), to(More)
