Wide-neck and giant cerebral aneurysms are difficult to treat with conventional endovascular or surgical means [1]. Recently, stand-alone stent treatment has been explored as a viable treatment option for these aneurysms. Two goals of standalone stent design are to permit flexible conformation of the stent through tortuous vessels and to provide sufficient coverage across the aneurysmal neck [2]. Stents that achieve those goals can facilitate the long-term physiological processes that exclude the aneurysmal sac from circulation. Thrombosis within the sac is an important intermediate step, which may begin with the elimination of aneurysmal inflow [3].
