内血管动脉瘤修复 (EVAR) 失败,如I型和III型内漏,需要重新干预. 了解设备特定的故障模式对于长期监测和成功的EVAR结果至关重要.
科学领域:
- 血管外科 血管外科
- 血管内干预 血管内干预
- 大动脉动脉瘤修复修复
背景情况:
- 在内血管动脉瘤修复 (EVAR) 后的I型和III型内泄漏会导致严重的并发症,需要重新干预.
- 不同的内移植器件在整个随访期间可能会呈现出不同的故障模式.
研究的目的:
- 审查对1型和3型内脏泄漏以及各种器械的其他严重故障进行大动脉内脏移植再干预的机构经验.
- 分析与不同EVAR设备相关的故障模式和结果.
主要方法:
- 在2002年至2019年期间,对在EVAR后接受开放转换或主要内血管干预进行I/III型内泄症的患者进行了回顾性审查.
- 收集了229名患者的基线特征,程序细节,再干预类型和结果.
主要成果:
- 1A型内皮漏洞是再次干预的最常见迹象 (63.8%),其次是IB型 (20.1%),IIIA型 (16.6%) 和IIIB型 (6.5%).
- 靠近的迁移是常见的AneuRx设备,类型III内泄与AFX设备,和类型IB内泄与Ancure设备.
- 18%的患者呈现出破裂动脉瘤,9%的患者在重新干预时有症状.
结论:
- 随着时间的推移,EVAR设备的严重故障模式会发生变化,需要对设备进行特定监控.
- 了解遗留的内移植失败模式对于定制长期监测和修复策略至关重要.

Types of Errors: Detection and Minimization
Absolute error in a measurement is the numerical difference from the true or central value. Relative error is the ratio between absolute error and the true or central value, expressed as a percentage.
Errors can be classified by source, magnitude, and sign. There are three types of errors: systematic, random, and gross.
