case_images: A1 fenestration [Figures 2a and b]. After performing the imaging at the working angle [Figure 3a], a 4-Fr Cerulean (Medikit Co., Ltd., Tokyo, Japan) was guided into the cavernous portion of the ICA, and SL10 (Stryker, Kalamazoo, MI, USA) with a 45  steam shape at 1 mm and 3 mm from the tip, respectively, was guided into the aneurysm using Traxcess (Terumo Corporation, Tokyo, Japan) [Figure 3b]. Then, Target 360 nano (2 mm x 3 cm; Stryker, Kalamazoo, MI, USA) was implanted [Figure 3c]; as no cerebral aneurysm was observed, the procedure was completed [Figure 3d].
