    through study completion, an average of 1 year

Secondary Outcomes (4)

  • Duration of hospitalization

    through study completion, an average of 1 year

  • Duration of total operating time

Study Arms (2)

Traditional therapy

OTHER

Consists of microsurgical aneurysmal operating techniques, endovascular techniques for intracranial aneurysms, endovascular techniques for cerebrovascular stenosis, and carotid endarterectomy, which are presented by stages.

Procedure: Microsurgical aneurysmal operating techniquesProcedure: endovascular techniques for cerebrovascular stenosisProcedure: endovascular techniques for intracranial aneurysmsProcedure: carotid endarterectomy

Hybrid operation

EXPERIMENTAL

Consists of microsurgical aneurysmal operating techniques, endovascular techniques for intracranial aneurysms, endovascular techniques for cerebrovascular stenosis, and carotid endarterectomy, which are presented in one-stage in hybrid operating theater.

Procedure: Microsurgical aneurysmal operating techniquesProcedure: endovascular techniques for cerebrovascular stenosisProcedure: endovascular techniques for intracranial aneurysmsProcedure: carotid endarterectomy

Interventions

The microsurgical techniques used to evacuate the aneurysm out of circulation or reduce its risk of rupture by aneurysmal clipping, wrapping,or isolation.

Also known as: microsurgical aneurysmal clipping, microsurgical aneurysmal wrapping, microsurgical aneurysmal isolation
Hybrid operationTraditional therapy

The endovascular techniques that recanalize the narrowed or occluded cerebrovascular, including stent implantation, balloon dilatation.

Also known as: endovascular stenting, endovascular balloon dilatation
Hybrid operationTraditional therapy

The endovascular techniques that embolize the cavity of aneurysms to reduce the risk of rupture, including coiling embolization, balloon-assisted occlusion.

Also known as: endovascular coiling, endovascular balloon occlusion, flow diverter
Hybrid operationTraditional therapy

A microsurgical technique to recanalize the stenosis or occluded proximal segment of carotid artery.

Hybrid operationTraditional therapy

Eligibility Criteria

Age18 Years - 70 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • For aneurysms:
  • with diagnosed complex intracranial aneurysm by digital subtraction angiography(DSA);
  • got SAH in history;
  • neural functional deficits due to aneurysms;
  • with \<4 in Hunt-Hess Grades;
  • ≥5.0mm in the maximum diameter;
  • \<70 years old;
  • with irregular morphological features and high rupture risk.
  • and for stenosis
  • Intracranial vessels:
  • \>50% in rate of stenosis with ischemic symptoms/perfusing evidence/lacunar infarction in supplying territory, failed in conservative treatment;
  • with a deliverable position of intracranial stents devices.
  • or Vertebral arterial system:
  • ≥70% in the rate of stenosis, with contralateral vertebral arterial occlusion;
  • symptomatic vertebral arterial stenosis, accompanied with posterior inferior cerebellum artery derived from the affected artery and related symptoms are caused/clinical benefits can be achieved through angioplasty.
  • +3 more criteria

You may not qualify if:

  • \>70 in age, with low rupture risk;
  • stroke history in 6 weeks (contraindication for endovascular intervention);
  • coexistence with intracranial tumor or AVM;
  • cannot tolerant the operation;
  • patient or relative refuses to participate the trail

Model Details: Patients of intracranial aneurysms with coexistence of cerebrovascular stenosis, coincident with inclusion and exclusion criterion, will be distributed into traditional therapy group(control group) and hybrid operating group(test group), and conduct with traditional neurosurgical management or one-stage hybrid operating management separately. Traditional therapy group: intervene the aneurysms and vascular stenosis unsimultaneously. Clipping procedure is preferred to aneurysms, while endovascular intervention is preferred to stenosis. Hybrid operation group: one-stage hybrid operating technique is conducted. The aneurysms and vascular stenosis will be executed via the cooperation of microsurgical procedure and endovascular interventional techniques.
