Abstract
BACKGROUND: The Woven EndoBridge (WEB) device is a new treatment modality developed for broad-necked unruptured intracranial aneurysms (IA) but shows potential for the treatment of ruptured IAs as well. Our aim was to describe 6-month aneurysm obliteration rates, clinical outcomes and procedure related complications after WEB treatment for ruptured IAs from two academic centers.
METHODS: We conducted a retrospective observational study, including all consecutive patients treated with the WEB device (WEB Single Layer [SL] and Single-Layer Sphere [SLS]) for a ruptured IA causing acute subarachnoid hemorrhage (SAH) between 2014 (start of use) and 2017. Primary outcome was angiographic aneurysm obliteration (Beaujon Occlusion Scale Score [BOSS]) rate. Secondary outcomes were early re-bleedings, complications and patient outcome (death and modified Rankin Scale).
RESULTS: A total of 33 patients with ruptured IAs were treated 0-4 days from IA rupture. Out of 27 survivors, six-month angiographic follow-up was available for 26 patients, out of which 81% showed complete occlusion. Of the 27 survivors, 24 patients (89%) had a favorable neurological outcome at six-months after SAH. Two aneurysms were re-treated (8% of all). There was one fatal procedure related complication. No early aneurysm re-bleedings were noted.
CONCLUSION: For anatomically suitable ruptured IAs, WEB device treatment seems to be safe and results in acceptable occlusion rates. Still, larger studies with long-term results are needed before recommendations can be made.
