ABSTRACT
INTRODUCTION: Woven EndoBridge (WEB) is an innovative device for the treatment of intracranial aneurysms especially wide-necked bifurcation aneurysms. Here we present our experience with the WEB device. MATERIAL AND METHODS: Patients treated using only the WEB device between September 2014 and November 2018 were included in the study. Follow up imaging studies and medical records of the patients were retrospectively reviewed. RESULTS: Forty-two aneurysm of 42 patients (27 female, 15 male; median age: 56, range: 32-76) were treated using the WEB device. The mean diameter of the aneurysms was 6.6â¯mm (range: 3-12â¯mm). The neck diameter was ≥4â¯mm in 57% of the aneurysms. The locations of the aneurysms were the middle cerebral artery bifurcation in 29 (69%), basilar tip in 5 (12%), anterior communicating artery in 5 (12%), internal carotid artery tip in 2 (5%), and M1 segment of the middle cerebral artery in 1 (2%) of the patients. Five patients had subarachnoid hemorrhage due to aneurysm rupture. The device could be successfully deployed in all of the cases. There were control imaging studies available for 36 patients who were followed up for a median of 7â¯months (range: 1-33â¯months). Adequate occlusion was observed in 35 of these 36 patients (97%). There was no treatment related morbidity or mortality. CONCLUSION: Although long term follow-up data are not available, WEB intrasaccular flow disruptor seems to be effective and safe for intracranial bifurcation aneurysm treatment in the mid-term follow up.
