Abstract： 目的通过检测钨丝弹簧圈血管内治疗前后30例病人血钨浓度以证实其在体内的溶解和吸收现象以及吸收与再通的关系.方法随机抽取应用钨丝弹簧圈栓塞的30例病人进行调查.动静脉畸形(AVM)14例,硬脑膜动静脉瘘(DAVF)6例,动静脉瘘(AVF)5例,颈动脉海绵窦瘘(CCF)2例,动脉瘤3例.分别于术前及术后留取非抗凝血5ml并进行高速离心,取血清应用电感耦连等质子光谱仪(ICP-MS)经双盲法测定血钨浓度并进行自身配对统计学处理.对栓塞后的病人全部检查其肝肾功能及电解质.结果栓塞后血钨浓度明显升高(P＜0.01).虽然血钨浓度明显升高,但病人的肝肾功能及电解质无异常.结论钨丝弹簧圈栓塞后在体内存在溶解和吸收现象,但金属钨对人体并不产生毒性.弹簧圈吸收后,动脉瘤不会复发,但AVM肯定复发.
