Endovascular treatment of intracranial aneurysm

The standard treatment of intracranial aneurysm is neurosurgical craniotomy and clipping. We developed intravascular treatment for these aneurysms because we encountered some cases that were difficult for surgical clipping. Between 1986-2000, we did embolization of the aneurysm by parent artery occlusion in 20 cases of intracranial aneurysm. In 1988-1995 detachable balloon, coil, and tissue adhesive to put inside the aneurysm for embolization in 24 patients. In 1997, Interlocking detachable coil was used in one patient. In 1997-2000, GDC was put inside the lumen of the aneurysm in 40 cases. As the materials for embolization improves with time, the treatment of intracranial aneurysm becomes safer. Endovascular treatment may become the treatment of choice for intracranial aneurysm in the future.
