Abstract/OtherAbstract:
Partial splenic arterial embolization (50% reduction in flow) was evaluated in dogs using polyvinyl alcohol foam or microspheres (20-500 mu) made of dextran, polystyrene, or silicone. Dextran and polystyrene were found to be superior for several reasons: they were easier to use, did not shatter when agitated, and produced permanent, homogeneous, peripheral occlusion with only one administration. Partial embolization with dextran or polystyrene increased platelet levels within 1 week and markedly reduced splenic size with minimal if any collateral filling within 6 weeks. Microscopically, no acute infarction or necrosis was seen at 6 weeks; there was some fibrosis, but the remaining parenchyma appeared normal.
