Filter by:Objective: To observe the practical application of the standardized green channel treatment system for stroke in Xi 'an in the real world. Methods: Clinical data and information of patients with acute ischemic stroke who received standardized green channel treatment for stroke were collected, and a multicenter observational clinical study was carried out in the real world to evaluate the prognosis, mortality, incidence of asymptomatic and symptomatic cerebral hemorrhage, incidence of pneumonia, and recurrence rate of stroke after 90 days.
The aim of the study was to establish a clinical and advanced imaging database of acute ischemic stroke patients treated with mechanical thrombectomy due to large vessel occlusion of anterior circulation within 24 hours from stroke onset in China, and to investigate the predictors and potential mechanisms of futile recanalization after mechanical thrombectomy.
The purpose of this study is to evaluate the safety and efficiency of normobaric hyperoxia combined with endovascular treatment for acute ischemic stroke patients with stroke onset 6-24 hours.
The overall incidence of good outcome for AIS following endovascular treatment is only proximately 50%. Whether NBO was safe and effective to improve acute ischemic stroke prognosis is still unclear. The investigators' hypothesis is thatNBO is a safe and effective strategy to improve longterm outcome in AIS patients undergoing endovascular treatment.
Based on the development of new tools, including drug coated balloon, paclitaxel eluting stent, interwoven stents, debulking tools, More and more acute or subacute thromboembolic occlusions of lower extremity included stage IIb were treated with endovascular procedures. Most guidelines suggests only stage I and stage IIa lesions are suitable for endovascular treatments. Therefore, a well-designed real-world study that track the safety and clinical relevant outcomes, are required to determine the optimal therapies for patients with acute or subacute thromboembolic occlusions of lower extremity.
Endovascular treatment（ET）is an effective therapy for acute ischemic stroke(AIS) with great vessel obstruction. However, acute complications such as high postoperative perfusion injury, hemorrhagic transformation and restenosis resulted in functional independence in only about 50% of patients 90 days after interventional surgery. Therefore, it is very important to protect the neurologic function after emergency endovascular treatment. The investigators' previous studies have shown that combined with intravenous thrombolytic therapy and remote postconditioning（RIPC）can significantly improve the neurological impairment and short-term and long-term prognosis in patients with acute stroke. In this multicenter, randomized controlled trial, the investigators assumed patients with acute ischemic stroke who had successfully revascularization after ET might benefit from RIPC as well. Patients in the RIPC group had five cycles of 5-min cuff inflation followed by 3-min deflation to the bilateral upper arm after ET. The primary endpoint measure was the proportion of patients with a favorable recovery of nerve function deficient assessed by Modified Rankin Scale （mRS≤2） 90 days after surgery. Secondary endpoints included the following: (1) Symptom endpoints: Neurological intelligence and function scores, postoperative hemorrhagic transformation rate, etc. (2) Blood index test: postoperative inflammatory factors, neuron-specific enolase (NSE) and other indicators. (3) Imaging endpoints: MRI-FLAIR , TCD, etc.
EVTRNA is to analyze the differentiated expression pattern of circular RNA (circRNA), long non-coding RNA (lncRNA) and micro-RNA (miRNA) by next-generation sequencing in acute ischemic stroke patients before and/or after endovascular treatment. The candidate circRNA/lncRNA/miRNA will be verified as the biomarker and regulator for progression and prognosis of acute ischemic stroke with endovascular treatment. Further, the candidate non-coding RNA will be used to evaluate the effect of endovascular treatment on both peripheral and central immune after stroke.
