About this study

Official title: Effects of Remote Ischemic Pre-Conditioning on Neurologic Complications in Adult Ischemic Moyamoya Disease Patients Undergoing Encephaloduroarteriosynangiosis

In the present study, investigators evaluated whether RIPC reduce the major neurological complications in adult moyamoya disease patients undergoing encephaloduroarteriosynangiosis (EDAS).

Read the detailed description

BACKGROUND: Brain ischemia and injury contributed to perioperative morbidity and mortality in revascularization surgery. Remote ischemic preconditioning (RIPC), brief periods of ischemia followed by reperfusion, can provide systemic protection for prolonged ischemia. Previous study found combined remote ischemic pre- and post-conditioning can be effective in reducing neurologic complications and the duration of hospitalization in moyamoya patients undergoing direct revascularization.In order to investigate whether RIPC before EDAS can protect these patients from the perioperative and long-term complications, a prospective randomized controlled trial will be performed in the current study.

DESIGNING: About 328 patients who are eligible for carotid artery stenting will be randomly assigned in 1:1 ratio to RIPC group and sham RIPC group (control). Remote limb ischemic preconditioning (RIPC) is consisted of five 5-min cycles of bilateral arm ischemia/reperfusion, it is induced by a sphygmomanometer placed on bilateral arm and inflated to 200 mmHg for 5-min followed by deflating the cuff for 5-min, patients in the RIPC group will do it twice a day for at least five days before EDAS. Patients in the sham RIPC group receive sham RIPC treatment, which is consisted of five 5-min cycles of bilateral arm ischemia/reperfusion, induced by a sphygmomanometer placed on bilateral arm and inflated to 60 mmHg for 5-min followed by deflating the cuff for 5-min, they will do it twice a day for at least five days before EDAS. Cerebral injury is assessed by plasma Human Soluble protein-100B (S-100B) and Neuron specific enolase (NSE). Clinical outcomes are determined by cerebrovascular events (including ischemic stroke, transient ischemic attack (TIA), cerebral hemorrhage and transient neurological deficit) and death or dependent.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Remote ischemic preconditioningProcedure or surgery

    Also called RIPC

    Remote ischemic preconditioning consisted of five 5-min cycles of bilateral arm ischemia/reperfusion, which is induced by a sphygmomanometer placed on bilateral arm and inflated to 200 mmHg for 5-min followed by deflating the cuff for 5-min.

  • Sham remote ischemic preconditioningProcedure or surgery

    Also called Sham RIPC

    Sham remote ischemic preconditioning consisted of five 5-min cycles of bilateral arm ischemia/reperfusion, which is induced by a sphygmomanometer placed on bilateral arm and inflated to 60 mmHg for 5-min followed by deflating the cuff for 5-min.

  • EncephaloduroarteriosynangiosisProcedure or surgery

    Also called EDAS

    Encephaloduroarteriosynangiosis is an indirect revascularization surgery of moyamoya disease

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Patients With Cerebrovascular Events.

    Cerebrovascular events included ischemic stroke, transient ischemic attack (TIA), cerebral hemorrhage and hyperperfusion syndrome.

    Measured: postoperative one month

  2. Number of Patients Dependent or Death

    Dependent included the modified Rankin Scale (mRS) > 2. Death included any reason caused death.

    Measured: postoperative one month

Secondary outcomes (7)
  1. The Severity of the Ischemic Stroke after Surgery

    The severity of the ischemic stroke was evaluated by the white matter hyperintensities volume on the MRI, the neurological deficits duration and the Modified Rankin Scale (mRS) of patients.

    Measured: postoperative one month

  2. Number of Patients Occured Re-stroke at Follow-up Period

    Re-stroke included ischemic stroke and hemorrhagic stroke.

    Measured: 6 months and 12 months after EDAS

  3. Number of Patients Dependent or Death at Follow-up Period

    Dependent included the modified Rankin Scale (mRS) > 2. Death included any reason caused death.

    Measured: 6 months and 12 months after EDAS

  4. Number of Patients with Improved Neurological Function at Follow-up Period

    The modified Rankin Scale (mRS) decreased at the follow-up period compared to preoperative scores

    Measured: 6 months and 12 months after EDAS

  5. Perfusion Status of Patients at Follow-up Period

    The perfusion status detected by stages of pre-infarction period based on computed tomography perfusion imaging

    Measured: 6 months and 12 months after EDAS

  6. Number of Patients With Any Side Effects of Remote Ischemic Preconditioning (RIPC) Treatment.

    The side effects referred to any side effects of RIPC or sham RIPC treatment, not including the sides effect of medications and EDAS.

    Measured: From baseline to 12 months after treatment

  7. Participants Who Got New Diffusion-weighted Imaging (DWI) Lesions on Post-treatment Magnetic Resonance Imaging (MRI) Scans.

    The presence of ≥1 new brain lesions on DWI

    Measured: Within 48 hours after EDAS
