Registration Number

Lead Sponsor
Capital Medical University
Brief Summary

Moyamoya disease is a common reason of transient ischemic attack (TIA) and stroke in children. Remote ischemic conditioning (RIC) has been shown to prevent recurrent stroke in intracranial arterial stenosis, but it is unclear whether RIC can prevent TIA or stroke in children with moyamoya disease. This study aims to evaluate the effect of RIC on TIA/stroke in children with moyamoya disease.

Detailed Description

This study will provide insights into the preliminary proof of principle, safety, and efficacy of RIC in pediatric MMD patients, and this data will provide parameters for future larger scale clinical trials if efficacious

Primary Outcome Measures
NameTimeMethod
The incidence rate of transient ischemic attack(TIA)during baseline to 12months after therapy

TIA means transient ischemic attack, two neurologists will evaluate patients with ischemic symptoms and make diagnosis.magnetic reasoning imaging (MRI) scan will be performed to confirm intracerebral hemorrhage, and the imaging will be evaluated by two independent neuroradiologists who are blinded to the study assignment.

The incidence rate of ischemic strokeduring baseline to 12months after therapy

Two neurologists will evaluate patients with ischemic symptoms and make diagnosis.magnetic reasoning imaging (MRI) scan will be performed to confirm intracerebral hemorrhage, and the imaging will be evaluated by two independent neuroradiologists who are blinded to the study assignment.

Secondary Outcome Measures
NameTimeMethod
Palpation for tendernesschanges from baseline to 6, 12months after therapy

Professional doctors will definite whether there's a palpation for tenderness

The number of patients not tolerating RIC procedure,and refuse to continue the RIC procedureduring baseline to 12months after therapy

The investigator will record the number.

The score of National Institute of Health stroke scale scoreduring baseline to 12months after therapy

National Institute of Health Stroke Scale (NIHSS) is considered as a standardized assessment of neurological functions in the acute phase of stroke, and it is generally used to quantify patient's neurological impairments on 15 items in 11 fields of different neurological status.The score of the scale ranges from 0 to 42.And higher score indicates worse neurological function.The NHISS will be assessed by certified study investigator, who is blinded to the treatment assignment.

Cerebral perfusionchange from baseline to 12months after therapy

cerebral perfusion status in the operation side at 12 months posttreatment as assessed by single photon emission computed tomography (SPECT).

The mean blood flow velocity of cerebral vascular detected by TCCDchanges form baseline to 6months,12months after therapy

TCCD means tran-scranial color-coded duplex sonography.

Incidence rate of symptomatic intracerebral hemorrhageduring baseline to 12months after therapy

Symptomatic intracranial hemorrhage, including any subarachnoid hemorrhage associated with clinical symptoms and symptomatic intracerebral hemorrhage. Head computed tomography or magnetic reasoning imaging (MRI) scan will be performed to confirm intracerebral hemorrhage, and the imaging will be evaluated by two independent neuroradiologists who are blinded to the study assignment.

The rate of death and adverse eventduring baseline to 12months after therapy

All causes of death will be included to compute mortality at 12 months after therapy

The number of patients with erythema,and/or skin lesions related to RICchanges from baseline to 6, 12months after therapy

Professional doctors will check it and the investigator will record the number.

The number of patients with any other adverse events related to RIC interventionduring baseline to 12months after therapy

The investigator will record the number.

The level of matrix metalloproteinase 9 (MMP-9)change from baseline (pre-RIC treatment) to 6 months ,12 months after therapy

Blood samples will be drawn from cubital vein to test these biomarkersThese samples will be centrifuged immediately after collection and stored at - 80 until batch evaluation

The score of Modified Rankin scale scoreduring baseline to 12months after therapy

The Modified Rankin Scale Score (mRS) is the most comprehensive and most widely used primary outcome measurement to assess the neurological functional disability in contemporary acute stroke trials. The mRS is an ordinal, graded interval scale that assigns patients among 7 global disability levels, which ranges from 0 (no symptom) to 5 (severe disability) and 6 (death). The investigators will use mRS to evaluate the degree of disability or dependence during daily activities. The mRS will be assessed by certified study investigator, who is blinded to the treatment assignment.

The number of cerebral lacunar infarctionchanges from baseline to 12months after therapy

magnetic reasoning imaging (MRI) scan will be performed to confirm intracerebral hemorrhage, and the imaging will be evaluated by two independent neuroradiologists who are blinded to the study assignment.

Number of distal radial pulseschanges from baseline to 6, 12months after therapy

professional doctors will check the distal radial pulses

The score of ABCD2during baseline to 12months after therapy

When subjects are diagnosed as TIA within 12 months after therapy ,The investigators use this scale to evaluate the patients' risk of stroke who with TIA .The score of the scale ranges from 0 to 7, and the higher score indicates higher risk of stroke in the patients who with TIA.The scale will be assessed by qualified investigator who are blinded to the treatment assignment.
