FIG 1. Pre- and posttreatment images of an unruptured intracranial aneurysm in a 46-year-old woman who underwent occlusion with 3D Micrus coils.
A and B, Lateral (A) and anteroposterior (B) 3D angiograms of the right internal carotid artery show a periophthalmic aneurysm with a maximum sac size of 9 mm and a neck size of 6 mm.
C and D, Lateral road mapping image (C) and oblique unsubtracted angiogram (D) of the right internal carotid artery after placement of the first spherical coil (9-mm coil loop diameter) show that the 3D configuration of the coil provides an anatomically compliant frame within the aneurysm and a scaffold that covers the neck.
E and F, Lateral (E) and anteroposterior (F) subtracted posttreatment angiograms show complete occlusion of the aneurysm.
