Clinical Management of Cerebral Aneurysms-: Endosaccular

Eytan Raz et al. Neuroimaging Clin N Am. 2025 Aug.

Abstract

Although the concept of treating cerebral aneurysms by filling the sac from the inside (endosaccular) started many years ago first with detachable balloons and then coils, the use of a single metallic resheathable device acting as a flow disruptor is a much more recent innovation. The most studied device among these is certainly the WEB, which became part of standard clinical practice for treatment of wide-neck bifurcation aneurysms. This study reviews the most important features of the WEB device with a short summary of the most important literature. A small section at the end reviews also other endosaccular devices.

Keywords: Aneurysm; Artisse; Contour; Endosaccular; Flow disruptor; SEAL; WEB.
