Computed tomography demonstrated diffuse subarachnoid hemorrhage with no laterality [Figure 1a]. Cerebral digital subtraction angiography (DSA) revealed a very small aneurysm in the dorsal side of the AcomA [Figure 1a and b].
Postoperative cone beam computed tomography showing the implanted Low-prolife Visualized Intraluminal Support Junior stent from the left A2 to the right A1 covering the anterior communicating artery (a). 3D- RA at 3 months after the treatment demonstrating complete occlusion of the aneurysm (b).

Sufficient expansion and patency of the stent were confirmed [Figure 2a]. DSA at postoperative day 14 showed that the aneurysm remained unchanged; however, complete occlusion was achieved 3 months after the treatment [Figure 2b].
