【摘要】 目的 比较血管内弹簧圈栓塞术后不同改良的Raymond-Roy分级(MRRC)颅内动脉瘤患者近期及远期疗效。方法 纳入接受血管内弹簧圈栓塞术的颅内动脉瘤患者248例，按术后MRRC分级分为Ⅰ级、Ⅱ级、Ⅲa级和Ⅲb级，比较各组近期及远期疗效。结果 各组瘤体直径、瘤颈长度、动脉瘤位置、术前Hunt-Hess分级、手术方法和手术时长比较，差异均无显著性(P>0.05)。随MRRC分级提高，各组患者近期疗效改善率逐渐提高，恶化率逐渐降低(P<0.05)。248例患者中有53例出现复发，复发率为21.37%,MRRC分级Ⅰ、Ⅱ级患者远期复发率明显低于Ⅲa级和Ⅲb级患者(P<0.05)。结论 随MRRC分级提高，颅内动脉瘤患者近期疗效逐渐提高，远期复发率逐渐提高。更多还原

【Abstract】 Aim To compare the short-term and long-term efficacy of different modified Raymond Roy grading(MRRC) in patients with intracranial aneurysms after endovascular coil embolization. Methods 248 patients with intracranial aneurysms who underwent endovascular coil embolization were included. They were classified into grade Ⅰ, grade Ⅱ, grade Ⅲa, and grade Ⅲb based on postoperative MRRC grading. The short-term and long-term therapeutic effects of each group were compared. Results There were no significant differences in tumor diameter, tumor neck length, aneurysm location, preoperative Hunt-Hess grade, surgical procedure and surgical duration among all groups(P>0.05). As the MRRC grading increases, the improvement rate of short-term efficacy in each group gradually increases, while the deterioration rate gradually decreases(P<0.05). Relapse occurred in 53 of 248 patients, and the recurrence rate was 21.37%. The recurrence rate of MRRC grade Ⅰ and Ⅱ patients was significantly lower than that of MRRC grade Ⅲa and Ⅲb patients(P<0.05). Conclusion With the improvement of MRRC grading, the short-term efficacy of intracranial aneurysm patients gradually improves, and the long-term recurrence rate gradually increases.更多还原
