Filter by:This observational study was designed for observe the cerebral hemodynamics and dynamic cerebral autoregulation (dCA) after endovascular thrombectomy (EVT) in acute ischemic stroke (AIS) patients. And analysis the relationship between the dCA damage degree and hemorrhage transformation (HT) and clinical outcome. Patients: patients with AIS caused by middle cerebral artery or internal carotid artery occlusion who accepted EVT. dCA Examination: dCA examinations were performed at 24 hours, 48 hours, 72 hours, and 5 days after EVT. The objectives of the study were as follows: The changes of cerebral hemodynamics and parameters of dCA in different time periods after EVT were analyzed. So as to determine the correlation between hemodynamics and dCA change and HT and clinical outcome after EVT and to explore the predictors of HT and adverse clinical outcomes.
The efficacy and safety of methylprednisolone in acute ischemic stroke patients with large infarct cores (ASPECTS score < 6) due to anterior circulation large vessel occlusion have not been clearly established. This is a multi-center, randomized, double-blind, placebo-controlled trial to investigate early combination therapy with methylprednisolone for reperfusion in acute large core infarction.
Background: Stroke is a leading cause of mortality and disability globally, with acute ischemic strokes(AIS) due to Large Vessel Occlusion (LVO) presenting significant treatment challenges. Mechanical thrombectomy (MT) has emerged as an effective intervention for AIS within an 8-hour window from symptom onset. However, the potential to extend this window up to 24 hours for select patients could revolutionize outcomes for those arriving late at comprehensive stroke centers. This study investigates the efficacy and safety of Cerebrolysin as an adjunct therapy to MT in extended time window and improving patient recovery. Methods: We conducted a multi-center, prospective, randomized study within the Chang Gung Memorial Hospital system in Taiwan, targeting 100 AIS patients eligible for MT beyond the traditional 8-hour window. Participants were randomized to receive either standard care or Cerebrolysin post-MT, initiated within 24 hours of stroke onset and continued for 14 days. The study assessed neurological, neuropsychological, and biomarker outcomes at multiple time points post-stroke to evaluate the effects of Cerebrolysin on recovery. Results: The primary outcome will measure the proportion of patients achieving favorable functional outcomes (modified Rankin Scale 0-2) at 90 days. Secondary outcomes include the impact of Cerebrolysin on secondary hemorrhagic transformation, brain edema, mortality rates, and quality of life. The study aims to provide comprehensive data on the benefits of adding Cerebrolysin to the standard post-MT care, focusing on its potential to protect against reperfusion injuries and maintain blood-brain barrier integrity. Conclusion: By evaluating the role of Cerebrolysin in conjunction with MT, this study aims to extend the therapeutic window for AIS treatment, offering hope for improved outcomes for patients who would otherwise be ineligible for current reperfusion therapies. The findings may pave the way for new guidelines in stroke management, emphasizing the importance of integrated care approaches in enhancing patient recovery.
This study intends to construct the goal-oriented integrated intervention model for AIS in-hospital procedure through the spatiotemporal positioning and the P-D-C-A cycle for continuous improvement (FAST model). Then a multicenter, evaluator-blind, cluster-randomized controlled study aims to verify the validity and safety of this FAST model.
The purpose of this study was to evaluate the effectiveness of early administration of BXOS110 for injection in reducing overall disability in patients with acute ischaemic stroke.
The objective of this clinical trial is to determine whether rapid local ischemic postconditioning (RL-IPostC) is effective in preventing brain edema and safe in acute ischemic stroke (AIS) patients treated with mechanical thrombectomy. In this trial, researchers will block antegrade cerebral blood flow temporarily by the way of balloon inflation/deflation in AIS patients immediately after revascularization. It makes the ischemic reperfusion brain tissue have a capacity of adaptation through intermittent blood flow restoration. Researchers will evaluate the protective role and safety of different duration of balloon inflation/deflation. The optimal postconditioning intervention dose will be determined for further confirmative investigation.
Phase III Clinical Trial of GD-11 for Injection in the Treatment of Acute Ischemic Stroke - A Multi-Center, Randomized, Double-Blind, Parallel, Placebo-Controlled Phase III Clinical Study with the primary objective of evaluation of the efficacy and safety of GD-11 for injection in the treatment of acute ischemic stroke patients within 48 hours. The subject has a clinical diagnosis of acute ischemic stroke, within 48 hours from stroke onset to start of study treatment, with a National Institutes of Health Stroke Scale (NIHSS) between 6 and 20, had a total score of upper and lower limbs on motor deficits ≥ 2. The primary outcome is the proportion of subjects with mRS score ≤ 1 at 90 days after treatment.
The DOWN-SUITE study is multicenter, randomised, controlled, open-label clinical trial with blinded outcome assessment comparing collateral status in patients with acute ischemic stroke treated with an in-hospital application of head down tilt -10° to -15° (HDT15) versus usual positioning (0° to +30°) before endovascular mechanical thrombectomy. This study will involve adult patients who are eligible for mechanical thrombectomy and who have acute ischemic stroke due to left or right middle cerebral artery occlusion (M1 segment). The investigators hypothesise that HDT15, applied in acute ischemic stroke patients with a large vessel occlusion, will improve collateral circulation, prolong the survival of the ischemic penumbra and improve the clinical benefit from mechanical thrombectomy compared with standard of care (usual positioning 0° to +30°).
To establish a predictive model and scoring system for predicting severe complications after thrombectomy. This scoring system can be used to identify high-risk patients after endovascular thrombectomy, guide the early use of adjunctive interventions, and provide reference for future clinical trials.
Acute ischemic stroke with large vessel occlusion is a frequently occurring life-threatening condition. Although endovascular treatment can effectively open occluded vessels, the successful reperfusion rate exceeds 80%, but the rate of good prognosis is less than 50%. The current clinical focus is on how to improve futile recanalization. Tirofiban is widely used in the treatment of stroke, as it can effectively prevent vascular reocclusion and improve microcirculation perfusion. It has the potential to improve futile recanalization, but there is a lack of high-level evidence-based medical support. This multicenter, prospective, double-blind, randomized controlled trial was conducted to assess the effectiveness and safety of sequential tirofiban therapy following successful mechanical thrombectomy within 24 hours of onset.
