Sicherheit und Wirksamkeit von RIC bei pädiatrischen Patienten mit Moyamoya-Krankheit, die mit einer Revaskularisierungstherapie behandelt wurden (RIC-PMD)

11. November 2026 aktualisiert von: Ji Xunming,MD,PhD, Capital Medical University

Sicherheit und Wirksamkeit der ischämischen Fernkonditionierung bei pädiatrischen Patienten mit Moyamoya-Krankheit, die mit einer Revaskularisierungstherapie behandelt wurden

Revascularization surgery has been the standard treatment to prevent ischemic stroke in pediatric Moyamoya disease (MMD) patients with ischemic symptoms. However, perioperative complications, such as hyperperfusion syndrome, new infarct on imaging, or ischemic stroke, are inevitable. Remote ischemic conditioning (RIC) is a noninvasive and easy-to-use neuroprotective strategy, and it has potential effects on preventing hyperperfusion syndrome and ischemic infarction.

Zeitfenster
The score of National Institute of Health stroke scale score
Zeitfenster: change from baseline (preoperation) at 24 hours, 48 hours, 72 hours, and at 5-7 days or if discharged earlier

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.

change from baseline (preoperation) at 24 hours, 48 hours, 72 hours, and at 5-7 days or if discharged earlier
The score of Modified Rankin scale score
Zeitfenster: change from baseline (pre-RIC treatment) at 180 days after revascularization 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). We 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, at 90 days postoperation. The distribution of mRS will be compared between groups

change from baseline (pre-RIC treatment) at 180 days after revascularization therapy
Symptomatic intracerebral hemorrhage
Zeitfenster: during the first 180 days after revascularization 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.
