About this trial

This is an interventional prevention trial for Aneurysm

Eligibility Criteria

18 Years - undefined (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Age 18 years or older
  • Unruptured brain aneurysm deemed suitable for neuroendovascular repair
  • Normal baseline brain MRI
  • Female subjects of childbearing potential have a negative pregnancy test.
  • Signed informed consent prior to entering study

Exclusion Criteria:

  • Dissecting or mycotic brain aneurysm.
  • Planned endovascular vessel sacrifice as the primary modality for aneurysm treatment
  • Severe, sustained hypertension (SBP > 185 mmHg or DBP > 110 mmHg)
  • Contraindication for remote ischemic conditioning: severe soft tissue injury, fracture, or peripheral vascular disease in the upper limbs
  • Pre-morbid modified Rankin scale score of greater than 1
  • Patients with a pre-existing neurological or psychiatric disease that would confound the neurological or functional evaluations
  • Patients who are unable to have an MRI scan for any reason.
  • Currently participating or previously participated in any investigational drug or device study within 6 months

Outcomes

Primary Outcome Measures

The presence of ≥1 new brain lesions on DWI
Assessed by DWI

Secondary Outcome Measures

Number of new ischemic lesions
Volume of new ischemic lesions
National Institutes of Health Stroke Scale
Scores on the National Institutes of Health Stroke Scale (NIHSS) range from 0 to 42, with higher scores indicating more severe neurologic deficits.
Cerebrovascular events
Cerebrovascular events included ischemic stroke, hemorrhagic stroke, and TIA.
Nondisabling events
Scores on the National Institutes of Health Stroke Scale (NIHSS) range from 0 to 42, with higher scores indicating more severe neurologic deficits.National Institutes of Health Stroke Scale ≤3 or TIA is defined as nondisabling events
Modified Rankin Scale
Scores on the modified Rankin scale of functional disability range from 0 (no symptoms) to 6 (death).

5. Study Description

Brief Summary
The overall incidence of DWI positive for thromboembolic events following endovascular treatment of intracranial aneurysms is proximately 50%. Whether remote ischemic conditioning was safe and effective to reduce ischemic brain lesions on DWI after endovascular treatment of intracranial aneurysms is still unclear. The investigators' hypothesis is that remote ischemic conditioning is a safe and effective strategy to reduce new ischemic lesions in intracranial aneurysms patients undergoing endovascular treatment.
