Abstract: Objective: To discuss the management of complex condition in 15 cases during endovascular treatment for intracranial aneurysms Methods: Narrow necked aneurysms were embolized with GDC directly, wide-necked aneurysms were remodeled with stent, then were embolized with GDC In giant and false aneurysms the parent artery was embolized with detachable balloon or coil Results: 3 aneurysms in 3 cases were broken during embolization with GDC,but all were cured by continue embolization 3 cases of wide-necked aneurysms were cured by stenting combining with GDC Among 9 cases of giant and false aneurysms, 8 of them were cured but brain infarction occurred in 1 case because of anaemia Conclusion: Endovascular embolization with GDC or GDC combining with stent is a minimal traumatic, secure and effective method of treatment for intracranial aneurysms Of all the factors that can estimate the compensative capability of cerebral blood flow, anemia were very important while deciding to embolize the parent artery
