The HydroCoil Embolic System (HES) was developed to reduce recurrences of aneurysms relative to platinum coils. But the HydroCoil Embolic System was characterized with many limitations. The manufacturer had recognized the challenge and recently a new design of hydrogel-coated coil-HydroSoft has become available in the market as the new generation HydroCoil. We reported our initial experience using HydroSoft coil versus HydroCoil in our center.
75 aneurysms embolized primarily using HydroSoft Coils from July 2008 to May 2009 were compared with 66 volume- and shape-matched aneurysms treated with HydroCoils from March 2006 to August 2008. Outcome measures included length and number of coils used, contrast volume, and length of hospital stay. During embolization, a stable framework was first established with bare coils, and hydrogel-coated coils were used subsequently to increase the packing density. Follow-up angiographic results 6 months after treatment were evaluated among some of the patients.
Successful coil embolization was achieved in all patients. There were no differences in average total coil length used per aneurysm. There were no differences in length of hospital stay and packing density. HydroSoft coils were more suitable using as the finishing or final coil. HydroSoft coil decreased the procedure-related retreated rates, and aneurysm packing was finished with soft, flexible HydroSoft coil and decreased the neck remnant rates. Follow-up angiography in HydroSoft-treated patients at 6 months revealed aneurysm stability without significant residual neck.
HydroSoft coil allowed us to deploy coated coils with good packing density. A slight expansion of these coils at the neck can be expected to reduce neck remnant and potentially inhibit recurrence.
HydroCoil 栓塞系统（HES）的开发是为了降低相对于铂线圈的动脉瘤复发率。但是 HydroCoil 栓塞系统具有许多局限性。制造商已经认识到这一挑战，最近一种新的水凝胶涂层线圈-HydroSoft 已作为新一代 HydroCoil 在市场上推出。我们报告了我们在中心使用 HydroSoft 线圈与 HydroCoil 的初步经验。
2008 年 7 月至 2009 年 5 月，我们使用 HydroSoft 线圈对 75 个动脉瘤进行了主要栓塞，与 2006 年 3 月至 2008 年 8 月使用 HydroCoil 治疗的 66 个体积和形状匹配的动脉瘤进行了比较。结果包括使用的线圈长度和数量、对比剂体积和住院时间。在栓塞过程中，首先用裸线圈建立稳定的框架，然后使用水凝胶涂层线圈增加包装密度。一些患者在治疗后 6 个月进行了随访血管造影结果评估。
所有患者均成功实现了线圈栓塞。每个动脉瘤平均使用的总线圈长度没有差异。住院时间和包装密度没有差异。HydroSoft 线圈更适合作为收尾或最终线圈使用。HydroSoft 线圈减少了与程序相关的复发率，动脉瘤包装完成后使用柔软、灵活的 HydroSoft 线圈，减少了颈部残余率。在 6 个月时对接受 HydroSoft 治疗的患者进行的随访血管造影显示动脉瘤稳定，无明显颈部残留。
HydroSoft 线圈允许我们以良好的包装密度部署涂层线圈。这些线圈在颈部的轻微扩张可以预期减少颈部残余并潜在抑制复发。
