Height-preserving sizing method for the new Artisse intrasaccular device based on early findings from 26 cases of intracranial aneurysm embolization

In contrast to the Woven EndoBridge (WEB) device, excessive lateral compression and height reduction appear to undermine the stability of the Artisse 2.0. As a result, the device size for spherical or ovoid aneurysms can be determined using the '+1/-1' method, while the '+1/-0' approach is recommended for cylindrical aneurysms to improve neck coverage through height preservation. These proposed sizing strategies may serve as a practical interim solution until more clinical data and user experience become available.
