Filter by:Vitamin D has been shown to impact prognosis in a variety of retrospective and randomized clinical trials within an intensive care unit (ICU) environment. Despite these findings, there have been no studies examining the impact of hypovitaminosis D in specialized neurocritical care units (NCCU). Given the often significant differences in the management of patients in NCCU and more generalized intensive care units there is a need for further inquiries into the impact of low vitamin D levels in this specific environment. This study proposes a randomized, double-blinded, placebo-controlled, single center evaluation of vitamin D supplementation in the emergent NCCU patient population. The primary outcome will involve length-of-stay for emergent neurocritical care patients. Various secondary outcomes, including in-hospital mortality, ICU length-of-stay, Glasgow Outcome Score on discharge, complications and quality-of-life metrics. Patients will be followed for 6 months post-discharge.
Patients with intracerebral aneurysm will be screened for sleep apnea using out of center polysomnography/polygraphy. Baseline blood pressure and medication will be assessed. Patients will be followed for up to 5 years to examine the increase in aneurysm size, rupture rate and changes in medication.
After endovascular treatment of the intracranial aneurysm, recanalization may occur, with a risk of recurrent subarachnoid haemorrhage or long-term angiographic recurrences of aneurysms. Few data exist on patients' long-term follow-up after subarachnoid haemorrhage caused by ruptured intracranial aneurysms.
Aneurysmal subarachnoid hemorrhage (SAH) is a form of stroke in which secondary neurological deterioration is an important cause of mortality and morbidity. These secondary changes, so called delayed cerebral ischemia (DCI), are caused by lysis of erythrocytes which can react to form iron, an toxic substance to the brain. Iron chelators remove the excess of iron and are standard care in iron-overloaded patients. Deferoxamine (DFO) an chelator has not been evaluated in SAH patients. This study evaluates the safety of deferoxamine in SAH patients.
The purpose of this study is to examine the percentage of patients who present with abdominal aortic aneurysms (AAA) will also have intracranial aneurysms (IA) and conversely; to examine the percentage of patients who present with intracranial aneurysms will also have abdominal aortic aneurysms.
During the last decade, the embolization has become the treatment of choice for ruptured intracranial aneurysms, to improve the neurological outcome of patients. At the same time, for his safety, she also became the technique allowing prophylactic treatment of unruptured intracranial aneurysms discovered incidentally during imaging exams. Regarding patients with ruptured intracranial aneurysms, patients who survive often have a reduced quality of life while one in two has a good neurological outcome after embolization. Depression, anxiety and fatigue, whose the psycho-social impact is important, are often cited. This description has often been done without considering the realized type of treatment (surgery or embolization) and mostly of neurological and functional status of the patient remotely (disability or not in daily activities). Regarding patients with unruptured intracranial aneurysms, they are mostly asymptomatic and embolization is programmed. They would present an cognitive impairment in one case in five at 1 month of treatment. If depression, fatigue and difficult return to working life are logically found in patients with severe sequelae (disability in daily activities) of their ruptured intracranial aneurysms, the question arises for patients with a ruptured intracranial aneurysms with a favorable evolution and for asymptomatic patients with unruptured intracranial aneurysms. A precise status of these populations is necessary, especially as the discovery and treatment of their intracranial aneurysms is often early (between 40 and 60 years) and that their good neurological status should allow "a priori" to return easily at the active life.
Endovascular treatment of ruptured and unruptured intracranial aneurysms presents complications, mainly the thrombo-embolic complication. No specific studies have been conducted to study factors associated with the occurrence of thromboembolic complications (symptomatic or not) post endovascular treatment of intracranial aneurysms.
Intracranial aneurysm (IA) is an asymptomatic cerebrovascular abnormality affecting 3.2% of the general population. The devastating complication of IA is its rupture, resulting in subarachnoid haemorrhage that can lead to severe disability and death. Unfortunately, there are neither reliable clues nor diagnostic tools to predict the formation and/or the fate of an IA in a given individual. Also, there is no pharmacological drug available to prevent the rupture of aneurysm and subsequent subarachnoid haemorrhage. Current treatments are invasive with a significant risk of procedural morbidity. Thus, still now, the management of patients with IA remains extremely challenging and still controversial. Although the pathogenesis of IA has been the subject of many studies for the last decade, the mechanisms underlying IA formation, growth and rupture are still mostly unknown and relevant animal models of IA are not available. Familial history of IA predisposes to IA formation and rupture and increasing evidence suggest a genetic component of IA formation, with heterogeneous modes of inheritance and penetrance. This project, gathering neuroradiologists, geneticists and vascular biologists, addresses the urgent need to understand the pathogenic mechanisms of IA to develop diagnostic and predictive tools of risk of IA. The investigators propose to identify IA-causing variants by whole-exome sequencing in familial forms of the disease. The investigators hypothesises that the functional analysis of the causal / susceptibility variants thus identified will provide clues to understanding the pathological mechanisms of IA formation, and the bases for developing diagnostic tools. This project aims at meeting this challenge. Based on preliminary data that already allowed to identify such a variant, and the combination of genetic and functional investigations, the specific objectives of this project are: - To identify IA-causing variants in familial forms of the disease by whole-exome sequencing; - To understand the function of these genes/ variants in the formation and rupture of IA by molecular and cellular approaches and generation of relevant animal models; - To discover potential biomarkers of risk of IA formation and/or rupture.
The first purpose of this study is to find out the clinical benefit and risk of oral aspirin for unruptured intracranial aneurysm (small than 7mm) combined with cerebral ischemia in patients in the real world. The second purpose of this study is to get the prediction model of aneurysm's rupture in patients who has unruptured intracranial aneurysm (small than 7mm) combined with cerebral ischemia , and find out who is suitable for oral aspirin.
This study aims to investigating the efficacy and safety of low profile visualized intraluminal support (LVIS) stents for the treatment of ruptured intracranial saccular aneurysms. The follow-up duration is 1 year.
