Abstract

PURPOSE

To evaluate the safety and efficacy of covered stents for treatment of visceral artery aneurysms (VAA).

METHODS

This multicenter retrospective study included patients with VAAs who were treated with covered stents between January 2015 and December 2020. A total of 65 patients (mean age, 58 years; range, 27-89 years) with 70 VAAs (60 true aneurysms [86%], 10 pseudoaneurysms [14%]) were included. Of the 65, 48 patients (74%) were asymptomatic. Patient demographics, endovascular treatments, and follow-up results were analyzed.

RESULTS

All patients received covered stents. The mean diameter was 2.9 cm (range, 1.0-7.6 cm) for symptomatic aneurysms and 2.5 cm (range, 1.0-9.0 cm) for asymptomatic aneurysms. Of the asymptomatic aneurysms, 89% had a saccular shape. The mean distance between the ostium of the artery in which the aneurysm occurred and the aneurysm was 3.9 cm (median, 3.0 cm; range, 0.5-10 cm). Additional coil embolization was used in 7 aneurysms (10%). During the procedure, 68 (97%) aneurysms were completely excluded, while 2 (3%) had a Type Ib endoleak. After a mean follow-up of 20 months (range, 1-75 months), all patients were asymptomatic. Four endoleaks were recorded and left for close observation. Four stents (7%) had mild restenosis, while the rest of the stents were patent.

CONCLUSIONS

Placement of covered stents in patients with VAAs excluded aneurysms and maintained artery patency.

摘要

目的

评估覆膜支架治疗内脏动脉动脉瘤（VAA）的安全性和有效性。

方法

本多中心回顾性研究纳入了 2015 年 1 月至 2020 年 12 月期间接受覆膜支架治疗的 VAA 患者。共纳入 65 例（平均年龄 58 岁；范围 27-89 岁）70 个 VAA（60 个真性动脉瘤[86%]，10 个假性动脉瘤[14%]）。65 例患者中，48 例（74%）无症状。分析了患者的人口统计学资料、血管内治疗和随访结果。

结果

所有患者均接受了覆膜支架治疗。有症状动脉瘤的平均直径为 2.9cm（范围 1.0-7.6cm），无症状动脉瘤的平均直径为 2.5cm（范围 1.0-9.0cm）。无症状动脉瘤中，89%为囊状。动脉瘤发生部位与动脉开口之间的平均距离为 3.9cm（中位数 3.0cm；范围 0.5-10cm）。7 个动脉瘤（10%）额外使用了线圈栓塞。术中，68 个（97%）动脉瘤完全被排除，2 个（3%）发生 Ib 型内漏。平均随访 20 个月（范围 1-75 个月）后，所有患者均无症状。记录到 4 例内漏，予以密切观察。4 个支架（7%）有轻度再狭窄，其余支架通畅。
