[Endovascular neurointervention for cerebral aneurysm].
Embolization would have an advantage in the treatment of cerebral aneurysms by eliminating the need for craniotomy. The recent protocol of endovascular treatment for cerebral aneurysm is classified into two main categories; is parent artery occlusion and intra-aneurysmal embolization. For aneurysms with a broad neck and large sac, it is recommended to consider proximal arterial occlusion if tolerance is confirmed by cerebral blood flow study at the time of balloon Matas' test. Parent artery occlusion is a classical technique, but still mandatory and effective clinically. In patients who have aneurysms with a has well-defined neck and who are not good candidates for craniotomy, intra-aneurysmal embolization would be recommended as an alternative means of treatment. Care should be taken to prevent problems and complications, including careful catheter and guidewire manipulation. Careful selection of cases and appropriate pre-, intra-, and post-procedure patient management is essential. Since the clinical application of Gugliemi's detachable coil (GDC) started, the potential of endovascular treatment for cerebral aneurysm has changed considerably. Preliminary results of embolization using GDC suggest that endovascular treatment would offer marked improvement in the management of patients harboring cerebral aneurysms.
