Fjärrstyrd ischemisk konditionering för akut ischemisk stroke behandlad med mekanisk trombektomi (RECAST-MT) (RECAST-MT)
Säkerhet och effekt av ischemisk konditionering på distans för akut ischemisk stroke behandlad med mekanisk trombektomi (RECAST-MT): En multicenter, randomiserad, kontrollerad, öppen, blindad endpoint-försök
For patients with acute ischemic stroke caused by large vessel occlusion, endovascular thrombectomy has been demonstrated to be the most effective therapy, as approximately 90% of the occluded vessels can be recanalized. However, less than 50% of patients could achieve functional independence, and over 15% died 90 days after stroke. Although the mismatch of successful recanalization with poor prognosis can be attributed to many factors, the infarct core formed during thrombectomy and reperfusion injury after thrombectomy may be among the most important and effective neuroprotective strategies urgently needed.
Remote ischemic conditioning (RIC) is a noninvasive strategy in which one or more cycles of brief and transient limb ischemia confer protection against prolonged and severe ischemia in distant organs. In the transient focal cerebral ischemia-reperfusion model, the application of remote ischemic conditioning before reperfusion or both before and after reperfusion reduces reperfusion injuries and the final infarct size. Because patients with acute ischemic stroke who are treated with endovascular thrombectomy can achieve a high rate of recanalization after focal ischemia, this patient population is akin to the model of transient focal cerebral ischemia-reperfusion. Furthermore, a pilot study has determined the safety and feasibility of remote ischemic conditioning in patients undergoing endovascular thrombectomy. However, whether remote ischemic conditioning could provide clinical benefits to patients with acute ischemic stroke who are treated with endovascular thrombectomy urgently needs investigations.
This study aims to investigate the safety and efficacy of remote ischemic conditioning in improving functional outcomes of patients with acute ischemic stroke treated with endovascular thrombectomy and explore the effect of treatment duration on the treatment outcome of remote ischemic conditioning.
