可膨胀水凝胶弹簧圈在颅内动脉瘤急性破裂期栓塞中的应用

Application of the hydrocoil in embolization of acute ruptured intracranial aneurysms

目的 探讨可膨胀水凝胶弹簧圈（Hydrocoil）在颅内动脉瘤急性破裂期栓塞中的应用价值。方法应用Hydrocoil栓塞急性破裂期15例17个颅内动脉瘤，并选择同期应用裸性铂金弹簧圈栓塞的18例颅内动脉瘤进行对比分析。结果经X2检验。结果Hydrocoil栓塞的17个动脉瘤，致密栓塞16个、大部栓塞1个。裸性铂金弹簧圈栓塞的18例动脉瘤，致密栓塞11例、大部栓塞7例。两者疗效差异有统计学意义（X2=5．402，P〈0．05）。患者术后6个月至1．5年内DSA检查，应用Hydrocoil栓塞的患者无复发；应用裸性铂金弹簧圈栓塞的患者动脉瘤复发5例。两者复发率差异有统计学意义（X2=5．510，P〈0．05）。结论Hydrocoil可提高颅内动脉瘤的致密栓塞程度，并降低颅内动脉瘤栓塞术后的复发率。

Objective To study the application of endovascular treatment of the acute ruptured intracranial aneurysms with the hydrocoil. Methods Fifteen patients （treatment group） with 17 acute ruptured intracranial aneurysms were treated with the hydrocoils. In the same period, 18 patients （control group） with acute ruptured intracranial aneurysms were treated with the bare platinum coil. Results In treatment group, 16 aneurysms received dense embolization, and one aneurysm had subtotal embolization. In control group, 11 aneurysms achieved dense embolization ,7 aneurysms had subtotal embolization. There was a significant difference between the two groups （ X2 = 5. 402, P 〈 0. 05 ）. After follow-up by DSA from 6 months to l. 5 years, no recurrence was showed in the treatment group, while recurrence occurred in 5 cases in the control group aneurysm, with a significant difference between the two groups （X2 = 5.510, P 〈 0. 05 ）. Conclusion The hydrocoil is an effective therapy for the endovascular treatment of intracranial aneurysms with improving the packing density of intracranial aneurysm embolization and reducing the recurrence rate.
