O a r c r f o a o C omplex cerebral aneurysms remain a formidable challenge to the combined neurovascular team (1). Because the majority of such complex aneurysms were excluded rom the International Subarachnoid Aneurysm Trial, the quest ontinues regarding the best management strategy for such esions. Recent advances in endovascular techniques, especially he introduction of self-expanding stent for intracranial use, have reatly expanded the scope of intracranial aneurysms amenable o endovascular obliteration. As Fraser et al. (2) stated, complexecision making should be done based on case-based as well as vidence-based approaches. Durability of treatment for prevenion of rupture is important consideration and should be weighed gainst risks of various kinds of treatment especially in unrupured cases.
