Filter by:Mechanical thrombectomy (MT) with a stent retriever (SR) device is now the standard intervention in ischemic stroke with large vessel occlusion. Favorable outcome is strongly associated with the successful reperfusion status. New device of MT such as contact aspiration seems promising to increase reperfusion status and clinical outcome. The main hypothesis is to show the superiority of combining the use of contact aspiration with a stent retriever compared to a stent retriever alone in treatment of acute stroke due to proximal arterial occlusion. The primary endpoint is the rate of perfect reperfusion score at the end of the endovascular procedure.
This is a Phase II study to assess the safety and tolerability of DM199 in acute ischemic stroke patients. The study will be randomized, placebo controlled at multiple centers.
Cerebral infarction is a type of stroke that can lead to sometimes disabling sequelae. Among these sequelae, fatigue is frequently reported by patients. It is therefore important for doctors to understand why patients suffer from fatigue after cerebral infarction and to determine whether treatments given for the cerebral infarction may have an impact on this fatigue. The aim of this research was to study the frequency of fatigue after cerebral infarction, the associated factors, in particular the impact of treatments administered in the acute phase.
This is a single institutional registry database for the patients with stroke and cerebrovascular diseases. Stroke is the fifth leading cause of death in the United States. Despite extensive research, most of the patients die or suffer from varying degree of post-stroke disabilities due to neurologic deficits. This registry aims to understand the disease and examine the disease dynamics in the local community.
The cerebral amyloïd angiopathy ( AAC) is a disease characterized by deposits of beta-amyloid peptids in the walls of the arteries of young and average calibre of the brain and the leptomeninx. The incidence of the AAC increases strongly with the age and represents a major cause of spontaneous brain haemorrhage to people over 60. The main demonstration is the lobar brain haemorrhage, the other ones are bleedings under arachnoid cortical and microbleedings leading to cognitive decline. Anatomical studies reported the presence of cortical infarcts in patients having amyloïd deposits suggesting an association between asymptomatic cortical cerebral infarcts and AAC. However prevalence and meaning of these infarcts in patients having an AAC remain badly known because of studies on low number of patients and the rarity of radiological analyses of these infarcts .A better knowledge of these asymptomatic cortical infarcts would allow to dread better cognitive disorders(confusions) presented by these patients, and to develop preventive strategies. Besides, the risk factors of severity of the AAC are little studied.
A number of large trials have confirmed the benefits of thrombolysis in acute stroke, but there are gender differences. The authors sought to examine the relationship between sex and outcome after thrombolysis. Previous reports [1-6] concerning sex-related differences in stroke management and outcome are inconsistent and sometimes difficult to interpret, and so the reasons for gender disparities in stroke outcome have remained unclear. Functional outcomes and quality of life after stroke are consistently poorer in women despite adjustment for baseline differences in age and prestroke function, and the fact that comorbidities and clinical outcomes were not different between women and men [3, 7] . Once the reasons for these differences are better understood, intervention might be possible to help provide the best care for all patients. This work is a continuation and extension of the Ebrictus Study [8-10] . Prior work has suggested sex-based differences in thrombolytic therapy in subjects with acute stroke [11] .The authors will explore whether sex might modify the effect of thrombolysis on survival and functional outcomes in patients with acute ischemic stroke [12] beyond the usually evaluated time period of 6 months after stroke and compared this with the group without thrombolytic treatment.
Acute ischemic stroke (AIS) represents an economical challenge for health systems all over the globe. Despite increasing knowledge of the pathophysiology of AIS, there is no satisfactory treatment to revert the resulting brain damage. Changes of neuroactive steroids have been found in different neurological diseases. In this regard, the investigators have previously demonstrated that old patients with AIS show changes of plasma cortisol and estradiol concentrations, in that increased steroid levels are associated with a deterioration of neurological status and a worse cognitive decline. The present study assessed in patients with AIS if changes of behavior, brain-derived neurotrophic factor (BDNF) and nitrites (NO-2) (nitric oxide soluble metabolite) bear a relationship with the degree of hypercortisolism. To this purpose, the investigators recruited patients hospitalized at the Central Military Hospital emergency room within the first 24 hours of AIS. Subjects were divided into two groups, each one composed of 40 control subjects and 40 AIS patients, including men and women. The neurological condition was assessed using the NIHSS and the cognitive status with the Montreal Cognitive Assessment (MoCA test). The emotional status was evaluated using the Montgomery-Asberg Depression Rating Scale (MADRS), whereas the Modified Rankin Scale (MRS) was used to determine the functional condition. BDNF and NO-2 plasma levels were measured by ELISA and the Griess reaction method, respectively.
The purpose of this study is to determine the safety and feasibility of remote limb ischemic conditioning(RIC) in acute ischemic stroke patients who received r-tPA thrombolytic therapy.
This is a multi-centre, prospective cohort study. The aim of this study is to investigate causes, risk factors, clinical course, management and outcomes of severe ischaemic stroke in a real-world setting in tertiary hospitals in China. Patients with acute ischaemic stroke from nine tertiary hospitals in western China will be recruited. Participants will be visited within 24 hours after admission, on day 3, day 7 and at discharge, to collect their clinical data, blood biomarkers, and brain imaging. A structured telephone interview will be conducted for each participant at 3 months and 1 year after stroke onset, respectively, to collect their functional outcomes. In-hospital outcomes include haemorrhagic transformation, brain oedema and death, 3-month and 1-year outcomes include survival status (death or survival) and functional outcome (scores of modified Rankin scale, mRS).
Remote ischemic postconditioning (RIPC) is suggested to protect the cerebral cell against ischemia in various settings. However, the effect of RIPC in patients with acute ischemic stroke who undergo thrombolysis has yet to be examined. In this single-center, randomized controlled trial, we examined the effect of RIPC on the resolution of nerve function deficient in response to thrombolysis. Patients in the RIPC group had five cycles of 5-min cuff inflation followed by 3-min deflation to the bilateral upper arm after thrombolysis. The primary endpoint was the recovery of nerve function deficient assessed by National Institutes of Health Stroke Scale(NIHSS), Activities of Daily Living(ADL), Modified Rankin Scale(mRS), CT cerebral perfusion imaging (CTP) and CT angiography(CTA). Secondary endpoints included the following: angiogenesis assessed by the level of vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF).
