Immunohistochemical Characterization of Specific Inflammatory Tissue Reactions following Embolization with Four Different Spherical Agents in the Minipig Kidney Model

Pronounced immunomarker expression was seen 4 weeks after embolization with small Embosphere particles. However, in general, modern spherical embolic agents cause a fairly low level of inflammatory reaction. In the present experimental setting, which is highly sensitive for specific tissue-to-agent reactivity, Embozene presented with low inflammatory results.
