FIG 5. Angiographic and pathologic findings after coil occlusion. Selected views from angiographic (A, B, and C), macroscopic (D, E, and F), and microscopic (G, H, and I) studies performed 12 weeks after standard platinum (A, D, and G) and radioactive coil (B, C, E, F, H, and I) implantation. Arteries treated with standard platinum coils were recanalized (D and G). Arteries treated with radioactive coils exhibited either subocclusions or total occlusions. Suboccluded arteries treated with radioactive coils (B, E, and H) had increased fibrous tissue content while permitting restricted blood flow (B, arrow). Occluded arteries treated with radioactive coils (C, F, and I) showed uniform fibrous filling of the lumen. Original magnification in D through F, x5; original magnification in G through I, x20.
