Current endovascular devices for the treatment of ICAs and their advantages and limitations.

Device	Advantages	Limitations/Complications
GDCs (bare coils)	Gold standard for ICA endovascular treatment	Complete occlusion of 49–65%, high recurrence (44% in 5–6 years) and assisting devices required for the treatment of wide-necked ICAs
Hydrogel coils	Higher packing for improved aneurysm sac filling	Recurrence and complete occlusion are not better than GDCs
Liquid embolic devices	Potential higher packing and maximized aneurysm sac filling	High potential for device migration and FDA approval not granted yet
WEB	Designed for wide-necked aneurysms without assisting device	Limited occlusion, prone to compression in large ICAs, and very high recurrence (∼72%)
Flow diverter	Can treat complex ICA geometry and ideal for side-walled ICAs	Limited geometries can be treated, high delayed rupture and prone to immediate failure
TrelliX	Improved packing density	Not approved by the FDA yet (in clinical trial—NCT03988062)
