To determine technical feasibility and results of stent-assisted coiling of visceral artery aneurysms (VAAs) with self-expandable LEO PLUS neurointerventional stent.
In this retrospective study, 11 consecutive patients (mean age 61.9 y ± 8.9; range, 45-76 y) with VAAs (splenic, n = 3; common hepatic, n = 2; renal, n = 5; celiac, n = 1) treated with neurointerventional stents were included. MR angiography was evaluated for aneurysmal occlusion and patency of the parent arteries.
Technical success was 90.9%. A minor technical complication developed in 1 patient (9%), and thrombosis of the distal part of the stent was seen just after deployment in another patient, but it resolved after tirofiban injection. Complete occlusion was determined in all patients on MR angiography at 6-month follow-up.
Self-expandable LEO PLUS neurointerventional stents could become a useful tool in the treatment of VAAs. Studies with larger groups of patients, including control groups, are needed to assess the true outcome of this treatment method.
确定使用自膨式LEO PLUS神经介入支架辅助栓塞内脏动脉瘤（VAA）的技术可行性及结果。
在这项回顾性研究中，纳入了11例连续的接受神经介入支架治疗的VAA患者（平均年龄61.9岁±8.9岁；范围45 - 76岁），其中脾动脉瘤3例、肝总动脉瘤2例、肾动脉瘤5例、腹腔干动脉瘤1例。通过磁共振血管造影评估动脉瘤闭塞情况及供血动脉通畅情况。
技术成功率为90.9%。1例患者（9%）出现轻微技术并发症，另1例患者在支架置入后即刻出现支架远端血栓形成，但在注射替罗非班后血栓溶解。在6个月随访的磁共振血管造影检查中，所有患者均实现完全闭塞。
自膨式LEO PLUS神经介入支架可能成为治疗VAA的一种有用工具。需要开展纳入更大患者群体（包括对照组）的研究来评估这种治疗方法的真实疗效。
