Brief Summary

Currently, early reperfusion is considered as the most effective therapy for the treatment of acute ischemic stroke (AIS). Over the past 20 years, intravenous tissue plasminogen activator (IV tPA) has been demonstrated to be the only effective therapy for AIS. More recently, several large randomized clinical trials have concluded the superiority of endovascular mechanical thrombectomy for AIS. Furthermore, with the development of materials and techniques, the occluded artery can be recanalized with high percentage (60%-90%), and the rate of recanalization is still being improved. A great number of AIS patients are now eligible for revascularization therapy and there should be a good prognosis of AIS after recanalizing the occluded artery using mechanical thrombectomy. However, things are never as simple as wished to be. The rate of patients with functional independence is less than 50% and over 15% patients died at 3 months post thrombectomy. The discrepancy between the functional outcome and recanalization rates encourage researchers to explore strategies that further improving the functional outcome of AIS patients.

Remote ischemic conditioning has been demonstrated to reduce cerebral infarct size in mouse model of focal cerebral ischemia. And clinical researches demonstrated the protective effects of remote ischemic conditioning in AIS patient treated with IV tPA,. However, whether remote ischemic conditioning is safe and effective in protecting patients with large-vessel ischemic stroke and undergoing endovascular treatment is still unknown.

Detailed Description

In the present study, the investigators will assess the safety and feasibility of remote ischemic condition paired with endovascular treatment for AIS. A single arm of AIS patients treated with endovascular therapy will be recruited, and remote ischemic conditioning will be applied prior to reperfusion therapy and in combination with post reperfusion therapy.

Study Groups

RIC & ET

Remote ischemic conditioning paired with endovascular treatment. RIC is a physical strategy performed by an electric autocontrol device with cuffs placed on bilateral arms and inflated to 200 mmHg for 5-min followed by deflation for 5-min, the procedures is performed repeatedly for 5 times. Endovascular treatment of acute ischemic stroke is performed by experienced neuroradiologist according to the latest guideline from American Heart Association and American Stroke Association. It includes thrombectomy, intra-arterial thrombolysis, thrombus aspiration, stenting and balloon angioplasty.
