Blood blister-like aneurysms (BBAs) are rare cerebrovascular lesions that face serious challenges in surgical as well as endovascular treatment. In this paper, we present our experience in treating BBAs using the LVIS EVO stents. A total of 10 patients (mean age of 56.1 years) with 13 BBAs, who were admitted to our university hospital between April 2020 and November 2021 with a subarachnoid hemorrhage (SAH) due to aneurysm rupture, were treated using the LVIS EVO stents. Treatment of the BBAs consisted of stent-assisted coiling in four patients and stenting in six patients. The aneurysms were located within ICA (84.6%), VA (7.7%), and MCA (7.7%). Placement of the LVIS EVO stents was successful in all patients. No technical complications were observed. One in-stent thrombotic event occurred during the procedure. MRA for one-year follow-up was performed in nine patients. One patient died (Hunt and Hess Grade IV). LVIS EVO stents may be a beneficial treatment option for BBAs, as they provide high occlusion rates. However, the long-term efficacy remains uncertain.
血疱样动脉瘤（BBAs）是罕见的脑血管病变，在外科手术和血管内治疗方面面临严峻挑战。在本文中，我们介绍了使用LVIS EVO支架治疗BBAs的经验。共有10例患者（平均年龄56.1岁），患有13个BBAs，于2020年4月至2021年11月因动脉瘤破裂导致蛛网膜下腔出血（SAH）入住我院，接受了LVIS EVO支架治疗。BBAs的治疗包括4例患者采用支架辅助弹簧圈栓塞，6例患者采用单纯支架置入。动脉瘤位于颈内动脉（ICA）（84.6%）、椎动脉（VA）（7.7%）和大脑中动脉（MCA）（7.7%）。所有患者LVIS EVO支架置入均成功。未观察到技术并发症。术中发生1例支架内血栓形成事件。9例患者进行了为期一年的磁共振血管造影（MRA）随访。1例患者死亡（Hunt和Hess分级IV级）。LVIS EVO支架可能是治疗BBAs的一种有益选择，因为它们具有较高的闭塞率。然而，其长期疗效仍不确定。
