探讨LVIS支架在颅内破裂微小动脉瘤介入治疗中的安全性及有效性。

回顾性分析四川省医学科学院·四川省人民医院神经外科自2014年8月至2019年8月采用LVIS支架辅助弹簧圈栓塞的32例颅内破裂微小动脉瘤患者的临床资料，评价介入治疗的临床效果、手术并发症发生情况及预后情况。

32例患者均成功进行LVIS支架辅助弹簧圈栓塞术。术后即刻栓塞结果：Raymond分级Ⅰ级30例（93.8%），Ⅱ级2例（6.2%）；31例患者支架完全展开，1例患者支架展开不良。术后6~12个月，28例患者行DSA随访，其中Raymond分级Ⅰ级27例（96.4%）、Ⅱ级1例（3.6%）。临床随访32例，无再出血、致死、致残病例，改良Rankin量表（mRs）评分0分28例，mRs评分1~2分4例。随访期间32例患者均未出现脑卒中相关事件。

应用LVIS支架辅助弹簧圈栓塞治疗颅内破裂微小动脉瘤方法安全、有效，但需长期、大量样本病例的随访观察。

To investigate the safety and efficacy of LVIS stent in the treatment of intracranial wide-necked small aneurysms.

The clinical data of 32 patients with intracranial ruptured small aneurysms treated with LVIS stent-assisted coil embolization from August 2014 to August 2019 in the neurosurgery department of Sichuan Academy of Medical Sciences & Sichuan Provincial People’s Hospital were retrospectively analyzed. The clinical effect, complications and prognosis of interventional therapy were evaluated.

LVIS stent-assisted coil embolization were successfully performed in 32 patients. Raymond classification right after the surgery hinted grade Ⅰ in 30 patients (93.8%), grade Ⅱ in 2 patients (6.2%). There was 1 patient enjoying suboptimal opening of LVIS stent. Raymond classification 6-12 months after surgery hinted grade Ⅰ in 27 patients (96.4%), grade Ⅱ in 1 patient (3.6%). Modified Rankin scale indicated that 28 patients had 0 point and 4 had 1-2 point. No procedure-related complications occurred during follow-up.

The LVIS stent is safe and effective in the treatment of intracranial ruptured small aneurysms. The long-term efficacy remains to be confirmed by larger studies with longer follow-up duration.
