The purpose of this study is to evaluate the feasibility of the WEB device from a beginner’s point of view. Fifteen aneurysms were included. Aneurysm locations were the following: Acom (9), MCA (3), and basilar tip (3). The WEB devices were successfully delivered in all cases. Two patients changed their WEB size. Short-term angiographic occlusion was obtained in all cases. Aneurysm embolization with the WEB device appears feasible and effective. However, beginners should be better to try easy cases considering aneurysm height and the deviation of the aneurysm axis to the inlet flow line.

Disclosures D. Kim: None.
