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.

Arm Intervention/treatment
Experimental: Remote ischemic conditioning Device: remote ischemic conditioning
Remote ischemic conditioning is performed by using an electric autocontrol device with cuffs that inflated to a pressure of 200 mm Hg during the ischemic period (Patent No. CN200820123637.X, China)

Sham Comparator: Sham remote ischemic conditioning Device: sham remote ischemic conditioning
sham remote ischemic conditioning is performed by using an electric autocontrol device with cuffs that inflated to a pressure of 60 mm Hg




Primary Outcome Measures :
  1. The presence of ≥1 new brain lesions on DWI [ Time Frame: within 72 hours after endovascular treatment ]
    Assessed by DWI


Secondary Outcome Measures :
  1. Number of new ischemic lesions [ Time Frame: within 72 hours after endovascular treatment ]
  2. Volume of new ischemic lesions [ Time Frame: within 72 hours after endovascular treatment ]
  3. National Institutes of Health Stroke Scale [ Time Frame: 7 days or discharge ]
    Scores on the National Institutes of Health Stroke Scale (NIHSS) range from 0 to 42, with higher scores indicating more severe neurologic deficits.

  4. Cerebrovascular events [ Time Frame: 30 days ]
    Cerebrovascular events included ischemic stroke, hemorrhagic stroke, and TIA.

  5. Nondisabling events [ Time Frame: 30 days ]
    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

  6. Modified Rankin Scale [ Time Frame: 30 days ]
    Scores on the modified Rankin scale of functional disability range from 0 (no symptoms) to 6 (death).


Other Outcome Measures:
  1. Occurrence of adverse events and serious adverse events [ Time Frame: 30 days ]
    Occurrence of adverse events and serious adverse events
