Results
Out of the 16 treated patients,
no failure of deployment were witnessed,
while in four patients (25%) it was required to change the size of the first deployed WEB SL.
Average neck size was 3.6 mm (range 2.2-5.5 mm),
while average dome size was 5.1 mm (range 2.5-8 mm).
We registered only one procedural complication (6%) due to distal embolization during catheterization of the vessel which led to frontal ischemia with persistent disability at discharge (mRS: 4).
In the 12 patients that underwent radiological follow-up,
we recorded a good rate of aneurysm exclusion; with complete exlusion in 7/12 patients (58%) considered as a grade 0-0' on BOSS scale and grade A on Lubicz occlusion scale; 4 patients presented a small neck remnant that did not require intervention (33%).
Only one patient presented a significant aneurysm remnant at 3 months follow-up (BOSS grade: 3 and Lubicz scale grade: D) which required retreatment with flow-diverter deployment.
At clinical follow-up no rebleeding were witnessed; three patients died due to infective complications (mortality: 19%) during intensive care unit stay while one patient developed tetraplegia and was sent to hospice care (mRS: 5).
Overall patient morbidity was 19%.
