BACKGROUND AND PURPOSE This study arose from a need to systematically evaluate the clinical and angiographic outcomes of intracranial aneurysms treated with modified coils. We report the procedural safety and clinical outcomes in a prospective randomized controlled trial of endovascular coiling for ruptured and unruptured intracranial aneurysms, comparing(More)
Pulmonary arteriovenous malformations (PAVMs) are uncommon lesions, but are the cause of considerable morbidity and occasional mortality. They most commonly occur in association with hereditary haemorrhagic telangectasia and screening of families with this condition is therefore important. Embolization of PAVMs by coils is a well tolerated effective(More)
Sturge-Weber syndrome (SWS) is a neurocutaneous disorder that is typically associated with progressive neurological deterioration. We describe a 12-year-old girl with SWS who suffered a permanent cerebral insult as the result of a period of protracted status epilepticus. The case illustrates the unique susceptibility of patients with SWS to uncontrolled(More)
In this paper the authors describe the first use of a new liquid embolic agent (Onyx) to treat spinal cord arteriovenous malformations (AVMs). Because its properties make it more predictable to use than currently available liquid agents, the authors believe that this material has great potential in the endovascular management of both spinal cord and brain(More)
INTRODUCTION Cerebral angiography is an invasive procedure associated with a small, but definite risk of neurological morbidity. In this study we sought to establish the nature and rate of complications at our institution among a large prospective cohort of consecutive patients. Also, the data were analysed in an attempt to identify risk factors for(More)
AIM To assess the efficacy of stereotactic radiosurgery (STRS) for the treatment of dural arteriovenous fistulae (DAVF). MATERIALS AND METHODS Between November 1987 and December 1998, 17 patients with a total of 18 DAVF were treated with STRS at the National Centre for Stereotactic Radiosurgery, Sheffield. Clinical and radiological data was collected(More)
Modeling of flow in intracranial aneurysms (IAs) requires flow information at the model boundaries. In absence of patient-specific measurements, typical or modeled boundary conditions (BCs) are often used. This study investigates the effects of modeled versus patient-specific BCs on modeled hemodynamics within IAs. Computational fluid dynamics (CFD) models(More)
The purpose of this study is to describe our initial experience of imaging adults with localisation-related epilepsy using MR imaging at 3.0T. We discuss the findings in the context of the recently released NICE guidelines that provide detailed advice on imaging people with epilepsy in the UK. 120 consecutive people over the age of 16 years with(More)
Gluten sensitivity can manifest with ataxia. The metabolic status of the cerebellum was investigated in 15 patients with gluten ataxia and 10 controls using proton MR spectroscopy. Significant differences were present in mean N-acetyl aspartate levels at short echo time and N-acetyl aspartate/choline ratios at long echo time between the patient and control(More)
