Safety and Efficacy Study of Remote Ischemic Conditioning Combined With Endovascular Thrombectomy for Acute Ischemic Stroke Due to Large Vessel Occlusion of Anterior Circulation

Safety and Efficacy Study of Remote Ischemic Conditioning Combined With Endovascular Thrombectomy for Acute Ischemic Stroke Due to Large Vessel Occlusion of Anterior Circulation: A Multicenter, Randomized, Parallel-controlled Clinical Trial

The purpose of this study is to determine the efficacy and safety of remote ischemic conditioning for patients of acute ischemic stroke who underwent endovascular thrombectomy due to large vessel occlusion of anterior circulation.

Study Overview

• Status: Completed
• Conditions: Acute Ischemic Stroke
• Intervention / Treatment: Procedure: Remote ischemic conditioning; Procedure: Sham remote ischemic conditioning

Detailed Description

In this study, 498 cases of ischemic stroke who undergo endovascular thrombectomy within 24 hours from the onset are included in 10 centers in China according to the principle of random, and parallel control. The experimental group receive basic treatment and remote ischemic conditioning for 200mmHg, 2 times per day for 7 consecutive days. The control group receive basic treatment and remote ischemic conditioning control for 60mmHg, 2 times per day for 7 consecutive days. Two groups will be followed up for 90 days to evaluate the efficacy and safety of remote ischemic conditioning for patients of acute ischemic stroke who underwent endovascular thrombectomy due to large vessel occlusion of anterior circulation.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Active Comparator: RIC+Standard medical treatment; RIC+Standard medical treatment Remote ischemic conditioning (RIC) is induced by 4 cycles of 5 min of healthy upper limb ischemia followed by 5 min reperfusion. Limb ischemia was induced by inflation of a blood pressure cuff to 200 mm Hg. RIC will be conducted twice daily for 7 days after endovascular thrombectomy. Additionally, the patients will be treated with standard medical treatment according to the Guidelines for diagnosis and treatment of acute ischemic stroke in China 2018.
