OBJECTIVE
Suprarenal bare metal stent separation is a rare complication after endovascular aneurysm repair. In this report, two new cases of this type of device failure are presented and the literature is reviewed to identify similar cases and evaluate associated clinical characteristics.
METHODS
A literature search was conducted in March 2022 using PubMed, Embase, and The Cochrane Library, with MeSH terms including aortic aneurysm, stents, and device failure. Two authors independently selected studies eligible for inclusion.
RESULTS
Twelve patients with endovascular graft suprarenal bare metal stent separation were identified. Endovascular aneurysm repair (EVAR) devices were implanted between May 1996 and November 2017. Suprarenal bare metal stent separation was detected after a median duration of five years post-operatively.
CONCLUSION
Endovascular graft suprarenal bare metal stent separation demands a high level of awareness. A better understanding of the involved failure mechanisms and associated risk factors is required to further optimise EVAR follow up protocols.
目的
肾上腺裸金属支架分离是血管内动脉瘤修复术后一种罕见的并发症。在本报告中，介绍了两例这种类型的器械故障新病例，并对文献进行了回顾，以识别类似病例并评估相关临床特征。
方法
2022年3月使用PubMed、Embase和Cochrane图书馆进行文献检索，医学主题词包括主动脉瘤、支架和器械故障。两位作者独立选择符合纳入标准的研究。
结果
确定了12例血管内移植物肾上腺裸金属支架分离患者。血管内动脉瘤修复（EVAR）装置于1996年5月至2017年11月植入。术后中位时间5年后检测到肾上腺裸金属支架分离。
结论
血管内移植物肾上腺裸金属支架分离需要高度警惕。需要更好地了解相关的故障机制和相关危险因素，以进一步优化EVAR随访方案。
