FIG 3. Section obtained 12 weeks after embolization. Large vessels were packed with aggregated CELPHERE beads. The beads traveled to vessels approximately 200 µm in diameter without stretching the vessel wall or rupturing the internal elastic lamina. There is no evidence of perivascular hemorrhage or inflammatory change in the peripheral area. (Hematoxylin & eosin stain: A, original magnification x40; B, original magnification x100)
