Abstract
Complex, large, wide-neck aneurysms, but particularly partially thrombosed intracranial aneurysms (PTIAs), have a greater tendency to recanalize after coil occlusion. The Woven Endovascular Bridge (WEB) combines shape memory wires braided to a relatively uniform, dense surface, which may limit its compaction and its incorporation into an existing aneurysm clot and may thus reduce PTIA recurrence. To carry out a retrospective analysis of our experience with the WEB as part of a complex treatment in conjunction with other implants to assess the efficacy and safety of this technique. Among 43 aneurysms treated with the WEB in our center, eight complex, large, wide-neck aneurysms were treated in conjunction with other implants (additional WEBs, coils, stents, flow diverters). Six of these eight aneurysms were PTIAs. All patients were followed up by DSA between 3½ and 38 months. All eight (100%) of the complex, large, wide-neck aneurysms were treated successfully and without periprocedural adverse events (0%). At follow-up, the two non-thrombosed aneurysms were completely occluded, but all six PTIAs recurred (75%) and were re-treated. There was no morbidity or mortality in these eight patients. Treatment of large, complex aneurysms ...Continue Reading
