WEB as part of a multimodality treatment in complex, large, and partially thrombosed XXXX : a single-center observational study of technical success, safety, and recurrence.

INTRODUCTION: Complex, large, wide-neck @entity439 , but particularly partially thrombosed @entity438 (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 @entity439 and may thus reduce PTIA recurrence. OBJECTIVE: 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. METHODS: Among 43 @entity439 treated with the WEB in our center, eight complex, large, wide-neck @entity439 were treated in conjunction with other implants (additional WEBs, coils, stents, flow diverters). Six of these eight @entity439 were PTIAs. All @entity1 were followed up by DSA between 3   and 38   months. RESULTS: All eight (100%) of the complex, large, wide-neck @entity439 were treated successfully and without periprocedural adverse events (0%). At follow-up, the two non-thrombosed @entity439 were @entity2300 , but all six PTIAs recurred (75%) and were re-treated. There was no morbidity or mortality in these eight @entity1 . CONCLUSIONS: Treatment of large, complex @entity439 with the WEB in conjunction with other implants was technically successful and safe but did not prevent recurrence of partially thrombosed @entity439 in our center. PTIA re-treatment was possible and not limited by the previously placed WEB.
