Safety and Efficacy of Remote Ischemic Conditioning in Patients With Carotid Artery Stenosis Receiving Carotid EndArterectomy (SERIC-CASCEA)
Carotid Artery Stenosis
About this trial
This is an interventional treatment trial for Carotid Artery Stenosis focused on measuring Remote ischemic conditioning, Carotid artery stenosis, Carotid endarterectomy
Eligibility Criteria
Inclusion Criteria: Age≥18 years, <80 years, regardless of sex; Symptomatic or asymptomatic carotid artery stenosis. In symptomatic patients the degree of stenosis should more than 50% (Based on North American Symptomatic Carotid Endarterectomy Trial Collaborators (NASCET) Criteria), in asymptomatic patients the degree of stenosis should more than 70% (Based on NASCET Criteria); Baseline mRS 0-2; Can cooperate with and complete brain magnetic resonance imaging (MRI) examination; Signed and dated informed consent is obtained; Exclusion Criteria: Evolving stroke; Chronic complete occlusion of the carotid artery without obvious symptoms of cerebral ischemia; Severe dementia; The causes of cardiogenic embolism, such as rheumatic mitral or aortic valve stenosis, artificial heart valves, atrial fibrillation, atrial flutter, sick sinus syndrome, left atrial myxoma, left ventricular wall thrombosis or valve tumor, congestive heart failure, bacterial endocarditis, etc; Uncontrolled hypertension (defined as systolic blood pressure ≥ 180 mmHg or diastolic blood pressure ≥ 110 mmHg, despite medication taken at enrollment); Severe hepatic and renal dysfunction (defined as aspartate aminotransferase (AST) or alanine aminotransferase (ALT) ≥3 times higher than the upper limit of the normal range, creatinine >265umol/l (3mg/dl)); The patients who have the contraindication of remote ischemic conditioning treatment, such as severe soft tissue injury, fracture or vascular injury in the upper limb. Acute or subacute venous thrombosis, arterial occlusive disease, subclavian steal syndrome, etc; Pregnant or lactating women; He/She is participating in other clinical research or has participated in other clinical research or has participated in this study within 3 months prior to admission; Other conditions that the researchers think are not suitable for the group.

Remote ischemic conditioning (RIC) is induced by 5 cycles of 5 min of bilateral upper limbs ischemia followed by 5 min reperfusion. Limb ischemia was induced by inflation of a blood pressure cuff to 200 mmHg. RIC will be conducted twice daily for 6 consecutive days after enrollment. Additionally, the patients will be treated with carotid endarterectomy (CEA) and standard medical treatment according to the Chinese guideline for the secondary prevention of ischemic stroke and transient ischemic attack 2022.
