Filter by:Early identification of intracranial atherosclerotic disease (ICAD) may impact the management of patients undergoing mechanical thrombectomy (MT). The aim of the study is to develop and validate a scoring system for pre-thrombectomy diagnosis of ICAD in posterior circulation large vessel/distal medium vessel occlusion strokes (LVOs/DMVOs).
The investigators evaluated whether the characteristics of ischemic stroke patients, door-to-needle time, and stroke risk factors were predictive variables for different subtypes of post-alteplase hemorrhagic transformation of brain infarction.
This multicenter international prospective cohort study will include patients with AIS with a known or newly diagnosed anticoagulant-naïve AF. All centers will use the same transcranial Doppler machine for one-hour monitoring with bilateral 2-MHz probes within 24 hours of symptom onset. Recordings will be analyzed for MES by a blinded central reader. The primary aim is to determine the proportion of patients with MES and the association of MES with functional outcomes assessed by a modified Rankin scale (mRS) score at 90 days.
This study aims to explore the safety and efficacy of 0.9% normal saline （NS） infusion on stroke after intravenous thrombolysis (IVT), we decided to conduct this multi-centre randomized controlled trial for the first time. This trial will provide an innovative strategy to facilitate functional independence after stroke administered with IVT. This is a multi-center, randomized controlled two arm (1:1 ratio) clinical trial. The enrolled participators will be divided into NS group and control group randomly after confirming as acute ischemic stroke (AIS) according to symptoms and signs. In NS group, the patient will undergo NS 2000ml intravenous infusion swiftly after IVT, with the speed of 200ml/h. In control group, the patient will not undergo NS intravenous infusion after IVT. The primary efficacy is disability at days 90, as scored by means of the modified Rankin scale (mRS), dichotomized as a favorable outcome (a score of 0 or 1), or an unfavorable outcome (a score of 2 to 6). The secondary outcomes mainly comprise neurological deficits, disability, imaging and laboratory tests at each follow-up time. The safety outcomes include the cerebral edema at 24-hour post-IVT detected by cranial CT, the 24-hour fluctuation of blood pressure and the cardiac function detected by ultrasonic cardiogram within 3 days after IVT. Stata 15.1 and R software will be used for statistical analysis
The goal of this study is to develop a prognostic score for ischemic posterior circulation strokes, based on our previous work on with the ASTRAL scores (Acute STroke Registry and Analysis of Lausanne) on overall stroke prognosis, intracranial occlusion, recanalization and stroke recurrences. The main question it aims to answer is the modified Rankin score in 3 months after the event. Participants will be patients with acute ischemic stroke of the posterior circulation with mRS priot to event <3. All the data will be collected retrospectively from patients included in the ASTRAL registry between January 2003 and December 2021. The ASTRAL registry will be used as the derivation cohort of the score. Demographics, acute glucose, NIHSS score and acute imaging of each participant will be used from the derivation cohort in order to create an integer-based prognostic score. After internal validation, we plan to validate the score in external stroke registries to show its validity.
The CHOICE study suggested that the use of adjunct intra-arterial alteplase after successful endovascular reperfusion in large vessel occlusion acute ischemic strokes may result in a greater likelihood of excellent neurological outcome at 90 days. However, CHOICE was a phase-2 trial and almost exclusively enrolled anterior circulation occlusions. Therefore, data on the safety and efficacy of post-endovascular reperfusion IAT in posterior circulation stroke is lacking. In general, anterior circulation strokes are associated with a higher risk of ICH than posterior circulation strokes. Therefore, we believe it might be safer to perform post-endovascular reperfusion IAT posterior circulation stroke. Also, there are more perforator artery in the posterior circulation, IAT would be more likely to show its benefit. Therefore, we would like to explore IA rt-PA for posterior circulation stroke after successful MT in our RCT. In this study, one interim analysis will be performed when the enrollment volume reaches 50% of the total sample size (188 cases). DSMB will determine the premature termination or continuity of research.
The aim of this study is to evaluate the effect of early rehabilitation treatment by electroencephalographic neurofeedback on upper limb motor function after stroke. Researchers will compare : Interventional group: electroencephalographic neurofeedback + traditional reference rehabilitation programme Control group: SHAM electroencephalographic neurofeedback + traditional reference rehabilitation programme
The goal of this observational study is to compare severity and mortality rates of acute cerebral infarction(requiring thrombolysis or endovascular recanalization) depending on the type of oral antidiabetic drug taken before the onset of cerebral infarction. Researchers will compare the group that used DPP-4 inhibitors as anti-diabetic drugs before cerebral infarction and the group that did not use them to see the effect of DPP-4 inhibitors in reducing severity of cerebral infarction.
The CBI registry is a prospective, interdisciplinary, multimodal observational registry of patients with covert brain infarction. Methods: A standardized workup in analogy to manifest ischemic stroke including cerebral MRI, long-term rhythm monitoring (3 x 7 days ECG), echocardiography, laboratory work-up and risk factor assessment as well as noninvasive angiography of the cervical and intracranial arteries will be performed.
Emergent reperfusion is the main goal for acute ischemic stroke therapy (AIS). Endovascular therapy (EVT) is recommended within 6 hrs of stroke onset, and up to 24 hrs following perfusion imaging criteria. Despite the major benefit associated with MT, more than 50% of the patients remain disabled at 3 months. Reperfusion rates after MT are critical to determine functional outcome. However, complete reperfusion is obtained in only 50 % of the patients, due to, at least in part, erratic emboli and/or no-reflow processes. The aim of this study is to evaluate the efficacy of glenzocimab in addition to EVT and compared to EVT plus placebo, whether or not associated with ntravenous thrombolysis (IVT), on functional outcome at day 90.
