Wide-neck aneurysms present a challenge in endovascular treatment. Multiple treatment options include balloon or stent-assisted coilings, flow diverters, and intra-saccular devices.

Balloon or stent-assisted coilings, though a viable option, presents higher complication risks and lower intra-procedural control in comparison to intra-saccular devices. In this case, due to the almost square aneurysm shape, wide neck, and a bifurcation location, a Woven EndoBridge (WEB) device was chosen due to its proven effectiveness and more experience at this institution (more than 8 years after the first trial). Slight compaction is sometimes seen on follow-up and especially more so over time, and is considered normal if it does in a dome to neck fashion, however, very few studies have been assessed this phenomenon.

Newer intra-saccular devices such as Contour have been released and are approved for use in some countries.
