Abstract: front page image
(EN)A liquid embolic material and a preparation method therefor. The liquid embolic material comprises an alkyl cyanoacrylate, Fe3O4 nanoparticles, and a contrast agent. The preparation method comprises dispersing Fe3O4 nanoparticles in the alkyl cyanoacrylate to obtain a suspension, and then adding the contrast agent to the suspension under argon, to obtain the liquid embolic material. After the liquid embolic material is injected into an aneurysm cavity, Fe3O4 nanoparticles and the alkyl cyanoacrylate can form a porous cross-linked body, thereby forming an embolism body.
(FR)La présente invention concerne un matériau embolique liquide et un procédé de préparation de celui-ci. Le matériau embolique liquide comprend un cyanoacrylate d'alkyle, des nanoparticules de Fe3O4, et un agent de contraste. Le procédé de préparation comprend la dispersion de nanoparticules de Fe3O4 dans le cyanoacrylate d'alkyle pour obtenir une suspension, et ensuite l'ajout de l'agent de contraste à la suspension sous argon, pour obtenir le matériau embolique liquide. Après que le matériau embolique liquide a été injecté dans une cavité d'anévrisme, les nanoparticules de Fe3O4 et le cyanoacrylate d'alkyle peuvent former un corps réticulé poreux, de manière à former un corps d'embolie.
