We have developed a liquid material for embolization of arteriovenous malformations that is a mixture of ethylene vinyl alcohol copolymer and metrizamide dissolved in dimethyl sulfoxide. Upon contact with blood, dimethyl sulfoxide rapidly diffuses into the blood and forms an ethylene vinyl alcohol copolymer elastic soft sponge that obstructs both the feeder and the nidus. The material, which is not adhesive, was used for embolization of three left cerebral arteriovenous malformations with satisfactory results.
我们已经研发出一种用于动静脉畸形栓塞的液体材料,它是乙烯-乙烯醇共聚物和碘海醇溶解于二甲基亚砜中的混合物。与血液接触后,二甲基亚砜迅速扩散到血液中,并形成一种乙烯-乙烯醇共聚物弹性软海绵,从而阻塞供血动脉和畸形血管团。这种非粘性材料用于栓塞三例左侧脑动静脉畸形,效果令人满意。
