Little is known about the effect of fMRI navigation in the intracranial arteriovenous malformation surgery. The investigators aim to perform a multicenter prospective randomized single -blind clinical trial to assess the effect and safety of fMRI navigation in the brain arteriovenous malformation surgery.

Primary Outcome Measures:
  • modified Ranking Scale [ Time Frame: six months after operation ]

    The scale runs from 0-6, running from perfect health without symptoms to death. 0-No symptoms.

    1. No significant disability. Able to carry out all usual activities, despite some symptoms.
    2. Slight disability. Able to look after own affairs without assistance, but unable to carry out all previous activities.
    3. Moderate disability. Requires some help, but able to walk unassisted.
    4. Moderately severe disability. Unable to attend to own bodily needs without assistance, and unable to walk unassisted.
    5. Severe disability. Requires constant nursing care and attention, bedridden, incontinent.
    6. Dead.

Secondary Outcome Measures:

Detailed Description:

Intracranial arteriovenous malformations (AVMs) are congenital lesions that consist of multiple arteries and veins, connecting as a fistula without an intervening normal capillary bed. Surgical removal is thought as a major treatment option for AVMs. However, compared with stereotaxic radiosurgery and endovascular embolization, microsurgery of AVMs is regarded with high mortality and morbidity, particular for high level classification AVMs .

Blood oxygen level dependent fMRI can be used to mapping the motor and language regions of the brain noninvasively. It has been one of the most advanced functional imaging techniques and it has quickly grown to be a vital tool for clinical and cognitive neuroscience research. Many clinical researches have been reported about the utility of fMRI in brain tumor surgery. However, the effect of fMRI navigation for neurofunction protection in the intracranial arteriovenous malformation surgery was unclear.

We aim to perform a multicenter prospective randomized single -blind clinical trial to assess the safety and effect of fMRI navigation in the intracranial AVMs surgery. We hypothesize that application of blood oxygen level dependent fMRI is able to improve long term prognosis of patients.
