Treatment of recurrent aneurysms using the Woven EndoBridge (WEB): anatomical and clinical results

Background The safety and efficacy of the Woven EndoBridge (WEB) for the treatment of naive intracranial aneurysms has been confirmed. Purpose To analyze the safety and efficacy of the WEB in the treatment of recurrent aneurysms. Methods Anatomical and clinical results in consecutive patients with a recurrent aneurysm, who were treated using the WEB device in two French neurointerventional centers, were evaluated. Results Seventeen patients with 17 aneurysms were included. Treatment was feasible in 16 patients. In seven patients (41.2%), ancillary devices were used. Permanent morbidity due to a thromboembolic complication occurred in one patient (5.9%). There was no mortality. Follow-up angiographic studies were available for 15 patients after a mean of 12.16.1 months. Rates of complete occlusion, neck remnant, and aneurysm remnant were 33.3%, 40.0%, and 26.7%, respectively. Conclusions Treatment of recurrent aneurysms using the WEB device may be reasonably safe and effective.
