To evaluate the clinical benefits and risks of hybrid operating techniques in management of complex intracranial aneurysms, which could coexists with multiple risk factors.
Purpose: Have an evaluation of clinical benefits and risks of hybrid operating techniques in management of complex intracranial aneurysms (CIAs), which could coexists with multiple risk factors. Meanwhile, as a new cooperative interventional modality, optimized workflows, technical key knots and operation routines will be explored in the study.
Objects: Patients with CIAs, coincident with inclusion and exclusion criterion and admitted in participating organizations.
Methods: Patients will be distributed into 2 groups, including traditional therapy group(control group) and hybrid operating group(trial group), and conduct with traditional neurosurgical management or one-stage hybrid operating management correspondingly. Peri-operative mortality rate is considered to be the primary observing indicator, and morbidity rate of peri-operative cerebral hemorrhagic/ischemic event, morbidity rate of aneurysmal residuals, morbidity rate of neural functional deteriorations, and health-economic indicators are secondary indicators.The information of operations will be recorded in detail as evidence of optimization of workflow and technical key knots.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Hybrid operation group | Experimental | Intervene with hybrid operating techniques, eg. microsurgical clipping+endovascular coiling or with the assistant of balloon occlusion. |

| Hybrid Operating Techniques | Procedure | It is a cooperation of existing endovascular interventional techniques and microsurgical techniques. Different from traditional management, hybrid operating techniques make it possible for 2 existing techniques conducting simultaneously in a hybrid operating theater. It optimizes the traditional microsurgical techniques for complex intracranial aneurysms and avoids the transportation of patients and the risks of intervals between stages in traditional ones. It includes balloon-assisted parental arterial occlusion, one-stage aneurysm clipping/wrapping/isolation and embolization/diverter implantation, etc. |
| Measure | Description | Time Frame |
|---|---|---|
| operation-related mortality rate | the mortality rate related to the operation | From the time of operation begin to 48 hours after operation |
| Measure | Description | Time Frame |
|---|---|---|
| Morbidity rate of peri-operative intracranial hemorrhage | Intracranial hemorrhagic events happening during the peri-operative period, including subarachnoid hemorrhage, intracranial hemorrhage, intraventricular hemorrhage caused by the rupture of aneurysms with neuro-imaging evidence. | From date of admission to the 7 days after operation |
