摘要
A histological staining technique that allows quantification of previously unmeasured parameters involved in surgical AVM embolization. The invention allows the evaluation of the polymerization characteristics of various ratios of embolization agents, such as Lipiodol/NBCA/glacial acetic acid (GAA) mixtures, by virtue of a new tissue sample preparation protocol and staining technique. ;To determine the depth of NBCA penetration within the AVM model and to characterize the polymerization patterns of various mixtures within a model vessel, histologic cross—and longitudinal sections were prepared for microscopy using a new staining method comprising the use of europium aryl-&bgr;-diketone complex and petroleum ether. Paraffin-embedded tissue sections were subjected to the staining protocol to improve differentiation between NBCA and Lipiodol.
