Neck coverage ratios for treated aneurysms at day 14. Largest dimensions of the orifice (OF) of the aneurysm and the fibrous membrane (FM) that covers the orifice were recorded and calculated as FM/OF proportion (fibrous membrane/ length of orifice × 100%). Standard GDC (n = 23), 48.3% ± 20.5%; collagen GDC-I (n = 11), 89.4% ± 14.9%; vitronectin GDC-I (n = 6), 71.5% ± 7.0%; laminin GDC-I (n = 4), 76.5% ± 11.0%; fibrinogen GDC-I, 74.8% ± 13.9% (n = 6); fibronectin GDC-I (n = 6), 87.5% ± 15.0%.
