Score Functional Outcome Questionnaire Response 0 No symptoms “I have no symptoms and I cope well with life.” 1 Minor symptoms “I have a few symptoms but these do not interfere with my everyday life.” 2 Some restriction in lifestyle “I have symptoms, which have changed my life but I am still able to look after myself.” 3 Significant restriction in lifestyle “I have symptoms, which have significantly changed my life and prevent me from coping fully, and I need some help looking after myself.” 4 Partly dependent “I have quite severe symptoms, which means I need to have help from other people but I am not so bad as to need attention day and night.” 5 Fully dependent “I have major symptoms, which severely handicap me and I need constant attention day and night.” 6 Dead Not applicable. Occlusion Grade No. of Aneurysms At treatment (n = 141) I 104 (74%) II 34 (24%) III 3 (2%) At follow-up (n = 94) I 74 (79%) II 17 (18%) III 3 (3%) Note—Average radiographic follow-up was 10 months. Occlusion grades were as follows: I, complete angiographic occlusion, no neck remnant, approximately 100%; II, subtotal occlusion, coils at the neck but some body filling or small neck remnant, approximately 95–99%; and III, incomplete occlusion, residual aneurysm body filling or sizable neck remnant or coil compaction, <95%.
