case_images: Preoperative DSA result (a and b) 3-dimensional (working angle) (c and d) 2-dimensional. Right ICA aneurysm, dome 20 mm x 14 mm, neck 13 mm. DSA: Digital subtraction angiography, ICA: Internal carotid artery.

case_images: The ICA aneurysm measured 20 mm x 14 mm with a neck of 13 mm in the right C1 segment on digital subtraction angiography (DSA) [Figure 1].
case_images: Operative image (a and d) VasoCT. (b and e) after the coil embolization (There was a shortening of the proximal side of FD after PTA). (c and f) Postoperative DSA result (working angle). FD: Flow diverter, CT: Computed tomography, PTA: Percutaneous transcatheter angioplasty, DSA: Digital subtraction angiography.

case_images: After the procedure, we confirmed the absence of intracranial hemorrhage using cone-beam computed tomography (CT) [Figure 2].
case_images: Computed tomography images of the sudden disturbance.
