We report the first use of Onyx in the embolization of spinal tumors in 2 cases of aggressive vertebral hemangioma. In both cases, Onyx embolization provided effective preoperative tumor devascularization after the initial prolonged particulate embolization with Embospheres made little overall impact. Onyx enables a more rapid and visible embolization than particles and is less technically demanding than traditional liquid embolic agents, such as n-butyl cyanoacrylate.
我们报告了在2例侵袭性椎体血管瘤的脊柱肿瘤栓塞中首次使用Onyx。在这两例病例中,在用Embospheres进行初始长时间颗粒栓塞后总体效果不佳的情况下,Onyx栓塞提供了有效的术前肿瘤去血管化。与颗粒相比,Onyx能实现更快速且可见的栓塞,并且在技术上比传统液体栓塞剂(如正丁基氰基丙烯酸酯)要求更低。
