Methods and materials
We retrospectively evaluated 16 patients,
14 of which were treated in emergency settings after subarachnoid haemorrhage due to aneurysm rupture.
All patients were evaluated pre-operatively with CT and CTA to analyze the dome-neck ratio and feasibility for the endovascular procedure.
During Digital Subtracted Angiography (DSA) we performed 3D-XA in all patients to better estimate shape and size of the aneurysm and select the appropriate "WEB SL" device.
Exclusion criteria were a dome-neck ration >1.6 which led to a different endovascular approach (coiling) or aneurysm size >1 cm due to lack of WEB large enough to treat them.
Radiological follow-up was performed,
when possible,
with DSA or CTA at 3,
6 and 12 months.
We evaluated aneurysm occlusion with both Beaujon Occlusion Scale Score (BOSS) and Lubicz occlusion scale.
Primary outcome was angiographic aneurysm obliteration.
Secondary outcomes were early re-bleedings,
complications and patient outcome (death and modified Rankin Scale).
