Revascularization and bypass procedures are useful in the treatment of complex aneurysms. Extracranial to intracranial bypass grafts are used to augment the distal circulation as an adjunct to proximal vessel occlusion for aneurysm treatment. Bypass grafts are used also to ensure adequate distal circulation during aneurysm trapping procedures. Recent improvements in vascular exposures at the skull base have allowed the development of vessel replacement or interposition grafts for arteries harboring aneurysms at the skull base. Intracranial interposition grafts are used to reconstruct arteries harboring aneurysms that cannot be occluded directly using clip or coil techniques. These techniques in the treatment of cerebral aneurysms are discussed.
