We present our experience and discuss the value of cerebral intravenous digital subtraction angiography (IV DSA) in the diagnosis of brain death. A total of 140 patients presenting with clinical signs of brain death were studied by IV DSA. According to the angiographic appearance of the vertebrobasilar system, the patients were divided into four groups.(More)
BACKGROUND Prognostication in comatose survivors of cardiac arrest is a major clinical challenge. The authors' objective was to determine whether an assessment with diffusion tensor imaging, a brain magnetic resonance imaging sequence, increases the accuracy of 1 yr functional outcome prediction in cardiac arrest survivors. METHODS Prospective,(More)
BACKGROUND AND PURPOSE Controversy still surrounds the question of when and how to manage cases of subarachnoid hemorrhage of Hunt and Hess grade IV and V aneurysms. Several authors are in favor of surgical treatment, reporting improved clinical outcomes and lower mortality rates. Considering that endovascular procedures are currently being increasingly(More)
BACKGROUND Existing methods to predict recovery after severe traumatic brain injury lack accuracy. The aim of this study is to determine the prognostic value of quantitative diffusion tensor imaging (DTI). METHODS In a multicenter study, the authors prospectively enrolled 105 patients who remained comatose at least 7 days after traumatic brain injury.(More)
To fulfill their crucial duty of relieving suffering in their patients, physicians may have to administer palliative sedation when they implement treatment-limitation decisions such as the withdrawal of life-supporting interventions in patients with poor prognosis chronic severe brain injury. The issue of palliative sedation deserves particular attention in(More)
French law 2005-370 of April 22, 2005 (Leonetti's law) brings new rights to patients and clarifies medical practices regarding end of life care. This new law prohibits unreasonable obstinacy in investigations or therapeutics and authorizes the withholding or withdrawal of treatments when they appear "useless, disproportionate or having no other effect than(More)
Spontaneous intracranial hypotension (SIH) is a well-known, but under- or misdiagnosed, condition caused by cerebrospinal fluid leak resulting from idiopathic dural breach. Blind lumbar epidural blood patch is an effective treatment in most cases, but occasionally, even targeted epidural blood patch fails to lead to improvement. In these cases, the(More)
BACKGROUND AND PURPOSE The aim of this study was to monitor the 24 h cerebrospinal fluid (CSF) outflow and intracranial pressure (ICP) in hydrocephalic adult patients with external ventricular drainage (EVD). PATIENTS AND METHODS Twelve patients (5M/7F) aged 30-69 years suffering from acute hydrocephalus requiring EVD were admitted in the neuro-intensive(More)
