PURPOSE Blood blister-like aneurysms (BBAs) have a high risk of early recurrence and postoperative rebleeding. This study compared the clinical outcomes and complications between endovascular intervention with low-profile visualized intraluminal support (LVIS) stent-assisted coiling and the surgical clipping in patients with BBAs. METHODS This retrospective study enrolled 39 patients with BBAs who underwent endovascular intervention with LVIS stent-assisted coiling (n = 21) or surgical clipping (n = 18) between January 2013 and July 2018. Primary outcomes were mortality and modified Rankin scale (mRS). Secondary outcomes were hospital stay, intensive care unit (ICU) stay and operation parameters. Complications were also retrospectively collated. RESULTS At baseline, the two groups were well balanced in patient characteristics. The hospital stays, ICU stays, operation time and intraoperative infusion volume were all significantly lower in LVIS group than that in clipping group (p < 0.05). A second operation was performed in 6 cases in the clipping group but none in the LVIS group (p = 0.006). The mean mRS score in the LVIS group was significantly lower than that of the clipping group both at hospital discharge and final follow-up (p < 0.001). Adverse outcomes occurred in 1 case in LVIS group and 7 in clipping group, with significant difference (p = 0.015). Complications were reported in 8 cases in LVIS group and 16 cases in clipping group, with significant difference (p < 0.001). CONCLUSION The endovascular intervention with LVIS stent-assisted coiling has better prognosis than surgical clipping. It decreased the risk of a second operation and procedure-related complications compared with surgical clipping.

使用低调可视化腔内支撑支架与手术夹闭血管内介入治疗血泡样动脉瘤：一项回顾性研究。

目的 血泡样动脉瘤 (BBA) 具有早期复发和术后再出血的高风险。本研究比较了血管内介入与低位可视化管腔内支持 (LVIS) 支架辅助线圈与 BBA 患者的手术夹闭之间的临床结果和并发症。方法 这项回顾性研究纳入了 39 名 BBA 患者，这些患者在 2013 年 1 月至 2018 年 7 月期间接受了 LVIS 支架辅助弹簧圈（n = 21）或手术夹闭（n = 18）的血管内介入治疗。主要结果是死亡率和改良的 Rankin 量表 (mRS) . 次要结果是住院时间、重症监护室 (ICU) 住院时间和手术参数。并发症也进行了回顾性整理。结果 在基线时，两组患者特征平衡良好。住院，LVIS组ICU住院时间、手术时间和术中输液量均显着低于夹闭组（p < 0.05）。夹闭组 6 例进行了二次手术，而 LVIS 组未进行二次手术（p = 0.006）。LVIS 组的平均 mRS 评分在出院和最终随访时均显着低于夹闭组（p < 0.001）。LVIS组1例、夹闭组7例出现不良结局，差异有显着性意义（p=0.015）。LVIS组8例报告并发症，夹闭组16例报告并发症，差异有显着性意义（p < 0.001）。结论 LVIS支架辅助弹簧圈血管内介入治疗预后优于手术夹闭。
