Outcome Measures

Primary Outcomes (4)

  • Instant residual rate of AVMs

    The instant post-operative residual rate of AVMs

    up to 1 week after operation

  • 3 months' residual rate of AVMs

    3 months' residual rate after AVM operation

    the date of 3rd month after operation, ±1 week

  • 6 months' residual rate of AVMs

    6 months' residual rate after AVM operation

    the date of the 6th month after operation, ±1 week

  • 1 year's residual rate of AVMs

    1 year's residual rate after AVM operation

    the date of the 12th month after operation, ±1 week

Secondary Outcomes (7)

  • Morbidity rate of post-operative complications

    7 days after operation

  • Post-operative mortality rate

    48 hours after operation

  • Morbidity rate of neural functional deterioration-48 hours after operation

    the assessing time points is 48 hours after operation

  • Morbidity rate of neural functional deterioration-1 week after operation

    1 week after operation

  • Morbidity rate of neural functional deterioration-3 months after operation

    the 3rd month after operation, ±1 week

  • +2 more secondary outcomes

Study Arms (2)

Traditional neurosurgical techniques

OTHER

Unsimultaneous endovascular interventional embolisation/radiotherapy followed by microsurgical resection, as traditional clinical routines.

Procedure: hybrid operating techniques

Hybrid operating techniques

EXPERIMENTAL

A one-stage hybrid operation combining endovascular intervention and microsurgical techniques will be conducted simultaneously

Procedure: hybrid operating techniques

Interventions

A one-stage cooperation of existing endovascular interventional techniques and microsurgical techniques, including microsurgical resection, endovascular embolization, balloon occlusion.

Also known as: endovascular interventional embolisation, endovascular interventional balloon occlusion, microsurgical resection
Hybrid operating techniquesTraditional neurosurgical techniques

Eligibility Criteria

Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • newly ruptured AVM with stable hematoma, selective operation is practical;
  • with rupture history;
  • recurrent epilepsy, failed in AED management;
  • giant AVM with deterioration of neurological functions;
  • grade AVM (Spetzler-Martin grading system) with no symptom and not located in eloquent area.

You may not qualify if:

  • \>70 in age, with low rupture risk;
  • newly ruptured AVM with unstable hematoma, engaged in emergency operation;
  • ≥5 grade in Spetzler-Martin grading system;
  • AVM located in hypothalamus, brainstem, cerebellopontine angle;
  • cannot tolerant the operation;
  • patient or relative refuses to participate the trail.
