Filter by:The purpose of this study is to determine the impact of in situ fibrinolysis on the mortality at 30 days in case of subarachnoid hemorrhage.
It is a "proof of concept" study, aimed to evaluate whether the "optimal CPP", defined by the best PRx, corresponds to the acceptable CBF values in patients affected by CBF disfunction caused by TBI or SAH.
The primary objective of this project is to investigate the effect of statin therapy on cerebral blood flow in patients with aneurysmal SAH who are randomized to receive or not receive statins in a blinded design.
The purpose of this study is explore how cerebrospinal fluid (CSF) drainage impacts outcomes for patients diagnosed with subarachnoid hemorrhage (SAH). This is a non-randomized observational study of two physician-prescribed approaches to managing intracranial pressure monitoring and CSF drainage for SAH patients. The study will enroll only those patients who have intracranial pressure (ICP) monitoring in situ. Because this is an observational study, there are no physical risks to the patient, the only risk is loss of confidentiality.
The study investigates safety, feasibility and effectiveness of cervical spinal cord stimulation (SCS) in prevention of cerebral arterial vasospasm following aneurysmal subarachnoid hemorrhage (aSAH). It is postulated that 2 week long stimulation of the cervical spinal cord using an implanted epidural electrode will prevent or decrease severity of cerebral arterial vasospasm following aSAH.
Intracranial bleeding from ruptured blood vessels (called a subarachnoid haemorrhage -SAH) affects 7000 patients each year in the UK and is a source of considerable death and disability, even in young adults. Recent observations indicate that these bleeds can cause reduced cerebral blood flow which leads to a bad outcome. High rates of death and disability occur, and are particularly prevalent when low cerebral blood flow results in stroke. Prevention of cerebral artery spasm and improvement in blood vessel reflexes are the target of modern therapy. Candidate drugs include statins which have an impeccable safety record and multiple potential beneficial actions (improve cerebral blood flow, reduce inflammatory processes, reduce adverse blood coagulation) following SAH. The investigators plan to use a statin, Simvastatin (40 mg) to improve cerebral blood flow and reduce inflammation. We have already completed a phase 11 study (n=80) which demonstrated potential benefits for acute statin therapy following SAH, and the investigators now wish to conduct a multi-centre phase 111 study to explore any potential clinical benefits in a larger population (n=1600). The purpose is to see whether the positive effects of statins seen in our phase II study translate into clinical benefits - both short term (e.g. reduced need for intensive care) and long term (outcome and wellbeing at 6 months).
In all the Western populations, the annual incidence of subarachnoid hemorrhage (SAH) increase with age. In patients older than 70 years, the occurrence of SAH exposes them to high risk of morbidity and a poor quality of life. In this age bracket, the single randomized which compared endovascular coiling to microsurgical clipping (ISAT Study) showed that the relative risk of morbidity increased after coiling. Moreover, some prospectives studies about endovascular coiling described favorable outcome in 48% to 63% of patients, complete occlusion in 51% to 69% and a procedural complication rate in 13% to 19%. From prospectives series, the proportion of favorable outcome after microsurgical clipping was estimated around 66% but the procedural complications are few reported. The outcome for patients treated conservatively was catastrophic. Lastly, the hydrocephalus in this age class is common, occurring in 55% of patients. The study hypothesis is that, in this age class, no difference exists between the 2 obliteration procedures. An accurate evaluation of result in term of functional disability, quality of life and prognosis predictive factors seems a judicious question.
The PRET study aims at comparing two types of coils used in the endovascular treatment of intracranial aneurysms. The first type made of platinum has been used for more than 15 years. The other, referred to as hydrocoil, containing in addition to platinum a polymer layer that expands when in contact with blood, has been in use since 2002. The hypothesis of the PRET study is that the newer hydrocoil will be more effective and yet as safe as the older platinum coil.
To show that the use of intravenous levetiracetam(LEV;Keppra)for seizure prevention in patients in the Neuroscience Intensive Care Unit will result in fewer side effects compared to the current standard of care anticonvulsant and will be at least as effective as the current standard of care in preventing clinical and sub-clinical seizure activity.
Subarachnoid haemorrhage (SAH) may cause damage to the hypotalamo-pituitary-adrenal axis (HPA) thus disturbing the hormonal response of these structures. The aim of our study is to characterize the function of HPA-axis acutely and over time up to three months in patients with SAH.
