Filter by:Stroke is one of the important causes of disability and death in the world, in which more than half were ischemic strokes. About 1/4 of the ischemic stroke occurred in the vertebral basilar artery system, especially when in the presence of extracranial proximal vertebral artery stenosis. Vertebral artery stenting is a minimally invasive method for the reconstruction of vertebral artery stenosis and the early clinical studies showed that it was feasible, safe and effective, but the high rate of restenosis has become a bottleneck restricting its development. Previous systematic review had suggested that the drug eluting stent might reduce the incidence of restenosis of vertebral artery. However, prospective randomized controlled trials comparing the efficacy of bare metal stents and drug eluting stents on the prevention of restenosis remains absent.
Intravenous thrombolysis with recombinant tissue-type plasminogen activator (IV t-PA) has been the only proven therapy for acute ischemic stroke (AIS) for almost 20 years. Whether IV t-PA prior to endovascular clot retrieval is beneficial for AIS patients with a proximal vessel occlusion in the anterior circulation has currently become a matter of debate and is a relevant unanswered question in clinical practice. The main objective is to determine whether subjects experiencing an AIS due to large intracranial vessel occlusion in the anterior circulation will have non-inferior functional outcome at 90 days when treated with direct mechanical thrombectomy (MT) compared to subjects treated with combined IV t-PA and MT. The secondary objectives are to study causes of mortality, dependency and quality of life in these AIS patients.
The present study aims to develope a risk assessment model of ischemic stroke endpoint events combining multi-dimensional traditional Chinese medicine(TCM) indicators with modern medicine indicators. The proposed study is a registry study based participant survey conducted in 7 hospitals nationwide in China. After obtaining informed consent, a total of 3000 study patients diagnosed with ischemic stroke will be recruited. 1-year follow-ups are carried out on-site in hospitals and by telephone to track endpoint events. At the same time, we conducted a prospective, multicenter, real-world longitudinal cohort study at 7 hospitals in China to investigate the clinical effectiveness of Qilong capsule (QLC) combined with CT for IS with Qi deficiency and blood stasis syndrome.
In this study, the investigators aim to evaluate the indirect revascularization outcomes of a new combination therapy of multiple burrhole procedure with promotion of arteriogenesis by intravenous (IV) erythropoietin (EPO) pretreatment on Moyamoya patients with acute neurological presentation, and outline the clinical and vascular factors associated with revascularization through the burrholes.
The aim of the study is to determine if single-bolus recombinant nonimmunogenic staphylokinase is effective and save thrombolytic agent in patients with ischemic stroke in comparison to alteplase.
When to start anticoagulation in patients with an acute ischaemic stroke and atrial fibrillation (AF) is a relevant unanswered question in clinical practice. Direct oral anticoagulants (DOACs) are highly effective for secondary stroke prevention in these patients, but DOACs were never initiated <7 days after stroke onset in recent trials. The ELAN trial will determine the net benefit of early versus late initiation of DOACs in patients with acute ischaemic stroke related to AF. The main objective is to estimate the net benefit of early versus late initiation of DOACs in patients with acute ischaemic stroke related to AF. The secondary objectives are to assess all vascular events and all-cause mortality after early initiation of DOACs in patients with acute ischaemic stroke related to AF compared to late initiation.
The purpose of this study is to assess the ability of the Fluids Monitor to detect hemispheric bioimpedance asymmetry associated with acute brain pathology in patients presenting with suspected Acute Ischemic Stroke (AIS).
Patients presenting with acute cerebral ischemic events are randomly assigned into aspirin (n=40) or cilostazol (n=40) group in a double-blinded manner. FMD is measured as a primary outcome at baseline (T0) and 90 days (T1). Serious and non-serious adverse events were described.
The purpose of this investigator-initiated study is to compare the use of pupilometer and ultrasound assessment of optic nerve sheath diameter in predicting the ICP and to see if there is a value that could be used to indicate elevated ICP with either modality as these numbers are inconsistent throughout the literature. Patients that have either an external ventricular drain (EVD) or bolt placed will be enrolled in the study. After the EVD and bolt are placed the patient will undergo pupilometer examination (standard of care) followed by ultrasound assessment of the optic nerve sheath diameter (ONSD). The three values will be recorded. The same patient may have multiple readings performed if there is a change in ICP either spontaneously or due to intervention.
The ESUS concept was introduced recently to describe a non-lacunar stroke of undetermined etiology. The following etiological workup is required in this setting: head CT or MRI, 12-lead ECG, transthoracic echocardiography, continuous cardiac monitoring for at least 24 hours after stroke, vascular imaging (ultrasound, magnetic resonance angiography, CT angiography, catheter angiography). Transesophageal echocardiography (TEE) is considered not to be required. However, aortic arch atheroma as diagnosed by TEE in the setting of recent ischemic stroke is a major aortic source of embolism, as supported by numerous well conducted studies. The European Association of Echocardiography considers that TEE is the gold standard for the diagnosis and the characterization of aortic atheroma. It is also the method of choice for the diagnosis of infectious endocarditis. The aim of this work was to evaluate the rate of patients with a therapeutic modification induced by TEE (mainly anticoagulation and surgery), in consecutive patients admitted with ESUS at our institution stroke unit.
