WEB Flow Disruption for Aneurysm Treatment

Laurent Pierot

Laurent Pierot

Endovascular treatment is now the first-line treatment for both ruptured and unruptured aneurysms.1,2  Some complex aneurysms (fusiform, wide-neck, large, and giant) are in some cases untreatable or difficult to treat with standard coiling. For this reason, more complex endovascular techniques have been developed, such as balloon-assisted coiling, stent-assisted coiling, and flow diversion.3,4

Intracranial broad-based aneurysms located at bifurcations remain a challenge for endovascular treatment. The WEB device (Sequent Medical, Aliso Viejo, California) was initially designed to address this kind of aneurysm. It allows placing within the sac of the aneurysm an intrasaccular device that will divert the flow towards the parent vessel.

From the very beginning, we have … more »

Intrasaccular flow disruption is an innovative endovascular aneurysm treatment. The WEB-DL (Woven EndoBridge Dual-Layer; Sequent Medical, Aliso Viejo, California) is an intra-aneurysmal flow disruption device developed to modify the  blood flow at the aneurysm neck and, therefore, to promote thrombosis of the aneurysm sac. It has been used mainly to treat complex wide-neck bifurcation aneurysms, and the … more »

During the last 10 years our department became a referral center for the development and the evaluation of new neuroendovascular devices. Therefore, I was asked more than 4 years ago, by the Sequent Medical company, to be among the first physicians to treat patients with the WEB device.

I have used this new endovascular tool strictly for complex … more »

Intrasaccular Flow-Disruption Treatment of Intracranial Aneurysms: Preliminary Results of a Multicenter Clinical Study

Thomas Liebig

Thomas Liebig

I have been focusing on interventional neuroradiology for about 15 years now and have conducted and supervised research on aneurysm treatment, especially flow diversion, with great interest. The technology described in this article is a combination of intrasaccular occlusion and flow diversion or disruption. The focus on ruptured aneurysms was a logical step because this … more »

The WEB aneurysm embolization system (Sequent Medical, Aliso Viejo, California) is a promising device dedicated to the treatment of challenging wide-neck intracranial bifurcation aneurysms. While this device is still under evaluation, preliminary results are promising.

In the department of Professor Jacques Moret in Paris (Neuri – Brain Vascular Center), we have been using C-arm VasoCT (Philips Healthcare, … more »
