Complete occlusion. Pre-embolization angiogram (A) and postembolization angiogram (B). Complete occlusion was achieved in the anterior communicating aneurysm of a 62-year-old woman. This unruptured aneurysm measured 8.2 mm × 6.0 mm × 6.8 mm. A total of 19 coils (136 cm) were deployed, of which 13 (116 cm) were PGLA-coated. Packing attenuation was calculated to be 68%.

Near-complete occlusion. Pre-embolization angiogram (C) and postembolization angiogram (D). Near-complete occlusion was achieved in the basilar top aneurysm of a 38-year-old man, presenting with subarachnoid hemorrhage. This aneurysm measured 12.8 mm × 10.2 mm × 10.9 mm. A total of 11 coils (185 cm) were deployed, of which 6 (105 cm) were PGLA-coated. Tiny contrast-filled spaces are seen near neck of the aneurysm. Packing attenuation was calculated to be 19%.
