FIG 2. Subarachnoid hemorrhage in a 37-year-old woman.
Left ICA angiogram (A) shows an anterior communicating artery aneurysm with a length of 11 mm and a width that varied from 5 to 7 mm.
Selective embolization with complex Orbit coils only: five coils were delivered within the aneurysm lumen including a 9 mm/25 cm coil (B), a 7 mm/21 cm coil (C), a 5 mm/15 cm coil (D), a 3 mm/3 cm coil. (E), and a 2 mm/2 cm coil.
Conventional nonsubstracted (F) and substracted (G) angiograms at the end of the procedure show a neck remnant.
Follow-up MRA (H) at 6 months shows a complete aneurysm occlusion.

FIG 3. Incidental cerebral aneurysm in a 44-year-old woman.
A, Left ICA angiogram shows a round 7 mm aneurysm of the ICA bifurcation.
Selective coiling with complex Orbit coils only: four coils were delivered in a concentric fashion within the aneurysmal sac including a 7 mm/21 cm coil (B), a 4 mm/7 cm coil (C), a 3 mm/4 cm coil (D), and a 2 mm/2 cm coil.
E, Conventional angiogram at the end of the embolization shows a complete occlusion.
F, Follow-up MRA at 6 months shows a slight recanalization of the neck (arrow).
