Abstract
The Woven EndoBridge (WEB) device’s effectiveness and safety have been thoroughly assessed in several clinical practice trials. The availability of new WEB sizes expanded the indications for the endovascular treatment of intracranial wide-necked aneurysms. We retrospectively analysed data from all patients with intracranial aneurysms treated with a 6 × 2 or 7 × 2 WEB in two institutions; endovascular embolization was performed both in unruptured and ruptured aneurysms. Seven patients with 7 wide-necked aneurysms were included; one aneurysm was ruptured. All aneurysms involved the anterior circulation. Technical success of embolization performed with flat WEB devices was accomplished and no intraprocedural complications occurred. At 3 months follow-up, adequate occlusion was obtained for six treated aneurysms. With the availability of new WEB sizes, broad-based aneurysms with unfavourable height and aspect ratio are suitable for embolization using intrasaccular flow disruption in our preliminary experience; larger series are needed to confirm their long-term efficacy.
