Repeated laser-assisted high-flow bypass for recurrent giant intracranial aneurysm. 
The treatment of intracranial aneurysms is changing as endovascular obliteration possibilities and long-term results are being published in regard to outcome.  However, not all aneurysms are amenable to direct endovascular or surgical treatment.  In such situations, a high flow bypass for flow preservation can be considered as indirect treatment alternative, enabling a trapping of the aneurysm or occlusion of the feeding artery.  We present the case history of a 57 year-old patient suffering of a recurrent giant intracranial carotid aneurysm.  The aneurysm could be excluded using a new cerebral high-flow bypass technique for which no temporary occlusion of any intracranial vessels is required.  This technique reduces the risks of perioperative neurological complications.
