动脉化疗栓塞是先经动脉灌注化疗药物后,再予以可吸收颗粒栓塞的一种技术,以期通过局部高浓度,延长药物作用时间和选择性缺血达到抗肿瘤作用[1～4]。栓塞剂的开发和应用是动脉化疗栓塞治疗中重要环节,理想的栓塞剂应具备以下条件:无毒、无抗原性、有好的生物相容性、易消毒、不 Arterial chemoembolization is a technique of first embolizing chemotherapeutic drugs via arterial infusion and then embedding absorbable particles in order to achieve anti-tumor effect through local high concentration, prolonged drug action time and selective ischemia [1 ~ 4]. The development and application of embolic agent is an important part in the treatment of arterial chemoembolization. The ideal embolic agent should have the following conditions: non-toxic, non-antigenic, good biocompatibility, easy disinfection, no
