Filter by:After acute ischemic stroke, the muscle strength of the limbs of the patients will decrease. Moreover, the respiratory muscles may also be affected. The respiratory muscle training may improve the respiratory recovery and prevent pulmonary complication.
The superiority of mechanical thrombectomy (MT) in patients with acute ischemic stroke from large vessel occlusion compared to standard medical therapy alone has been demonstrated by several randomized clinical trials and become the standard of care for these patients. A direct aspiration first pass technique (ADAPT) for the endovascular treatment of stroke using a large-bore catheter has been reported to be an effective method of achieving MT. Recent studies reported that ADAPT is as efficient and safe as stent retrievers, with a similar successful recanalization rate, but may have better functional outcomes, fewer procedure related-adverse events, and a tendency for faster revascularization compared to the stent-retriever thrombectomy. However, navigation of a large-bore aspiration catheter is not always possible due to unsuccessful passage of the ophthalmic artery origin ("ledge effect") or tortuous vascular anatomy. The coaxial technique comprises guiding the large-bore catheter with a smaller inner catheter and can facilitate distal access. However, there is a gap between the inner catheter and the distal tip of the large-bore outer catheter that creates a risk of damaging the vessel wall and causing dissection or subarachnoid hemorrhage. Even with this coaxial technique, it is not always possible to reach the clot site with the large-bore catheter. To decrease the gap between the two catheters, several authors have used, in place of the inner microcatheter, a compliant balloon catheter positioned and inflated at the distal tip of the large-bore catheter. The aim of the present study was to evaluate the safety and efficacy of ADAPT assisted by a compliant balloon (ADAPT-AB) when ADAPT using the coaxial technique fails to reach the clot site.
The regional health authorities of South-East Norway has commissioned Sørlandet Hospital (SSHF), Norway to establish mechanical thrombectomy in large-vessel occlusion stroke. SSHF is a limited volume stroke center, and introduction of thrombectomy may impose quality challenges. Therefore the implementation will be guided by a simulation based quality assurance program. In this study, we will monitor timelines, technical and clinical outcomes, including adverse events.
Non-invasive brain stimulation (tDCS) such as transcranial direct current stimulation (TDCS) has been reported to be effective in improving motor performance and safe in participants with cerebral infarction. However, few studies have been done in participants with acute cerebral infarction. In this study, the investigators want to see the effect of tDCS in acute cerebral infarction. the investigators perform tDCS in participants with acute ischemic stroke within 48 hours after stroke onset and the investigators measure motor weakness and function at early phase as well as at 3 months.
BALT has designed an electronic platform to continue collecting clinical data as part of the post-marketing clinical follow-up of its devices. This platform is purely exploratory, without hierarchical order of the objectives and associated outcomes.
This study aims to assess the incidence of atrial fibrillation (AF), documented using data recorded by an implantable Holter monitoring device (Reveal Linq, Medtronic) within 2 years after percutaneous closure of patent foramen ovale for cryptogenic stroke.
The CASES-TCM study is a prospective, multicenter, observational study, which will enroll 20,000 patients with acute stroke (ischemic stroke or intracerebral hemorrhage) within 7 days of symptom onset. This study attempts to depict major clinical characteristics of acute stroke in patients with Chinese medicine treatment and to explore any difference compared with other non-Chinese medicine use cohorts and the effectiveness and safety of Chinese medicine.
The management of cerebral infarctions (CI) is a real public health issue. The French National Authority for Health recommends Mechanical Thrombectomy (MT) either in combination with Intravenous Thrombolysis (IVT), or alone, after failure of IVT or in case of contraindication to IVT, within 6 hours of the onset of symptoms. The objective is to determine the factors predicting good functional recovery at 3 months in order to establish the typical profile of the "good responder" patient to MT and to evaluate functional recovery at 3 and 12 months (mRS ≤ 2) according to the modality of MT (depending on whether it is performed during the day or at night), the age of the patients, the equipment used for MT, the type of anaesthesia, as well as the impact of the metrics from the radiological evaluation in the patient's management. patient management.
The overall goal of the DISCOVERY study is to better understand what factors contribute to changes in cognitive (i.e., thinking and memory) abilities in patients who experienced a stroke. The purpose of the study is to help doctors identify patients at risk for dementia (decline in memory, thinking and other mental abilities that significantly affects daily functioning) after their stroke so that future treatments may be developed to improve outcomes in stroke patients. For this study, a "stroke" is defined as either (1) an acute ischemic stroke (AIS, or blood clot in the brain), (2) an intracerebral hemorrhage (ICH, or bleeding in the brain), (3) or an aneurysmal subarachnoid hemorrhage (aSAH, or bleeding around the brain caused by an abnormal bulge in a blood vessel that bursts). The investigators hypothesize that: 1. The size, type and location of the stroke play an important role in recovery of thinking and memory abilities after stroke, and pre-existing indicators of brain health further determine the extent of this recovery. 2. Specific stroke events occurring in individuals with underlying genetic or biological risk factors can cause further declines in brain heath, leading to changes in thinking and memory abilities after stroke. 3. Studying thinking and memory alongside brain imaging and blood samples in patients who have had a stroke allows for earlier identification of declining brain health and development of individualized treatment plans to improve patient outcomes in the future.
Dexmedetomidine can attenuate the activity of the sympathetic nervous system under stress response and improve ischemia-reperfusion injury. The investigators hypothesized that the prolonged sedation of dexmedetomidine after successful reperfusion of endovascular thrombectomy may improve the clinical outcome of acute ischemic stroke patients.
