Purpose Flow disruption with the WEB-DL device has been used safely for the treatment of wide-necked bifurcation aneurysms. The stability of aneurysm occlusion after this treatment was evaluated in short- and midterm, but not in long-term. This retrospective multicenter European study is the continuation of an already published series dealing with short-and midterm anatomical results and analyzes long-term data in patients treated with WEB-DL.

Methods Twelve European neurointerventional centers initially participated to the study. In addition to data collected for the initial publication, images obtained at long-term follow-up were collected and independently analyzed by the same experienced interventional neuroradiologist.

Results Out of the initial 45 patients, 26 (20 females and 6 males) aged 35 to 73 years (mean: 55.2 +/- 10.6 years; median: 55.5 years) harboring 26 aneurysms treated with the WEB-DL device had long-term follow-up (median: 27.4 months). Three out of 26 patients (11.5%) were retreated between short- and midterm follow-up and none between mid- and long-term. Long-term aneurysm occlusion in the 19 patients treated with WEB only and not retreated during follow-up was complete occlusion in 13/19 patients (68.4%) including aneurysms with opacification of the proximal recess (9/19 patients, 47.4%), neck remnant in 3/19 patients (15.8%), and aneurysm remnant in 3/19 patients (15.8%). In all patients (100.0%), aneurysm occlusion was stable between midterm and long-term follow-up.

Conclusions The results suggest that WEB treatment of wide-neck bifurcation aneurysms offers long-term stable occlusion.
