Suitability of cerebral aneurysms for endovascular treatment: Evolution of criteria with technological developments
With the introduction of electrically detachable coils in 1991 and later the results of the ISAT trial in 2002, endovascular approach became the primary treatment for cerebral aneurysms in many countries. The suboptimal quality of anatomical results and the relatively high rate of aneurysm recurrence after treatment still hamper an even more widespread of the technique. In this paper, we will make a review of the anatomical factors associated with poor anatomical results as well as technological developments aiming at improvement of aneurysm healing.
