[Effect analysis of treating intracranial wide-neck bifurcation aneurysms through Woven EndoBridge].

Objective: To explore the clinical effect of Woven EndoBridge (WEB) in the treatment of wide-neck bifurcation aneurysms. Methods: The clinical and imaging data of 11 patients with intracranial wide-neck bifurcation aneurysms treated by WEB alone at Department of Neurosurgery of the Northern Theater General Hospital from September 2017 to May 2018, were retrospectively analyzed. The patients were 7 males and 4 females, aged (54±11) years (ranged from 31 to 66 years). The aneurysms of 5 patients were located in the anterior communicating artery, 3 in the top of the basilar artery, and 3 in the bifurcation of the middle cerebral artery. The intraoperative and postoperative conditions of the patients were recorded, and the degree of aneurysm embolization was evaluated by WEB embolization aneurysm occlusion scale (WOS). Results: The intraoperative WEB release of all the 11 patients was good, with 3 cases of WOS grade A, 1 of grade B and 7 of grade C, with no intraoperative acute complications occurring. The imaging follow-up was not carried out in 1 patient due to economic reason, and the clinical follow-up was good until 3 years after the operation; 10 patients were followed up by imaging for 6 months to 3 years, and no postoperative complications occurred in the target treatment area. Among the 2 patients with WOS grade A and 1 patient with grade B during operation, according to the postoperative follow-up, all were WOS grade A; among the 7 patients with WOS grade C during operation, 4 were still of grade C and 3 were of grade D according to the follow-up. Among the 3 patients with WOS grade D, 1 patient received secondary embolization due to poor recurrence morphology, unstable hemodynamics and high possibility of rupture of aneurysm, stent assisted coil embolization was adopted, with good immediate effect; the other 2 cases had recurrent aneurysms, but the aneurysms had good morphology and stable hemodynamics, therefore, clinical follow-up was continued and no secondary surgery was performed. No complications occurred in all these 11 patients. Conclusions: The operation of treating unruptured intracranial wide-neck bifurcation aneurysms with WEB device alone is simple, and there is no need for anticoagulation and antiplatelet treatment before and after the operation, the clinical effect is being good. WEB device provides a new treatment option for intracranial wide-neck bifurcation aneurysms.目的： 探讨使用Woven EndoBridge（WEB）治疗宽颈分叉部动脉瘤的临床效果。 方法： 回顾性分析北部战区总医院神经外科2017年9月至2018年5月使用WEB治疗的11例颅内宽颈分叉部动脉瘤患者的临床和影像学资料。男性7例，女性4例，年龄（54±11）岁（范围：31~66岁）。动脉瘤位于前交通动脉5例，基底动脉尖3例，大脑中动脉分叉部3例。记录患者术中及术后随访情况，采用WEB栓塞动脉瘤闭塞量表（WOS）评估动脉瘤栓塞程度。 结果： 11例患者术中WEB均释放良好，术中WOS A级3例，B级1例，C级7例，无术中急性并发症发生。1例患者因经济原因未行影像学随访，临床随访至术后3年，恢复良好；10例患者获得影像学随访，随访时间6个月至3年，无患者出现术后靶治疗区并发症。2例术中WOS A级、1例WOS B级的患者，术后随访时WOS均为A级；7例术中WOS C级患者中，4例随访时仍为C级，3例为D级。在获得随访的3例D级患者中，1例因动脉瘤复发形态不佳、血流动力学不稳定、破裂出血可能性较大接受二次栓塞治疗，采用支架辅助弹簧圈栓塞术式，术后即刻效果良好；余2例虽动脉瘤复发，但动脉瘤形态良好，血流动力学稳定，故继续临床随访，未予以二期手术治疗。11例患者均无并发症发生。 结论： 使用WEB装置治疗颅内未破裂宽颈分叉部动脉瘤的手术操作简单，手术前后无需抗凝、抗血小板治疗，临床效果较好，为颅内宽颈分叉部动脉瘤提供了新的治疗选择。.
