摘要
Abstract
Objective To assess the embolic effects and biocompatibility of Eudragit mixture, a new liquid embolic agent.Methods In vitro, the viscosity and precipitation time of Eudragit mixtures at several concentrations were measured to study the best proportion of components of the mixture. In vivo, a branch of the right external carotid artery was embolized with Eudragit mixture in 12 rabbits, and with n-butyl cyanoacrylate in another 12 rabbits for a comparative study of the general, angiographic and histopathologic changes between the two groups.Results Eudragit mixture containing 7.5g Eudragit, 50ml absolute ethanol and 50ml iopromide was shown in vitro to have good properties including rapid precipitation and soft elastic sponge formation upon contact with blood; in vivo, to be nontoxic, nonadherent to the microcatheter and able to embolize the vascular lumen completely without later recanalisation.Conclusion Eudragit mixture is an effective, nontoxic, safe and promising liquid embolic agent.关键词
