Abstract：
Over the past two decades, there has been extensive research into surveillance methods for the post-endovascular repair of abdominal aortic aneurysms, highlighting the importance of these technologies in supplementing or even replacing conventional image-screening modalities. This review aims to provide an overview of the current status of alternative surveillance solutions for endovascular aneurysm repair, while also identifying potential aneurysm features that could be used to develop novel monitoring technologies. It offers a comprehensive review of these recent clinical advances, comparing new and standard clinical practices. After introducing the clinical understanding of abdominal aortic aneurysms and exploring current treatment procedures, the paper discusses the current surveillance methods for endovascular repair, contrasting them with recent pressure-sensing technologies. The literature on three commercial pressure-sensing devices for post-endovascular repair surveillance is analyzed. Various pre-clinical and clinical studies assessing the safety and efficacy of these devices are reviewed, providing a comparative summary of their outcomes. The review of the results from pre-clinical and clinical studies suggests a consistent trend of decreased blood pressure in the excluded aneurysm sac post-repair. However, despite successful pressure readings from the aneurysm sac, no strong link has been established to translate these measurements into the presence or absence of endoleaks. Furthermore, the results do not allow for a conclusive determination of ongoing aneurysm sac growth. Consequently, a strong clinical need persists for monitoring endoleaks and aneurysm growth following endovascular repair.
摘要：
在过去的二十年里，对腹主动脉瘤血管内修复后的监测方法进行了广泛的研究，强调这些技术在补充甚至取代传统图像筛查模式方面的重要性。这篇综述旨在概述血管内动脉瘤修复的替代监测解决方案的现状。同时还确定了可用于开发新监测技术的潜在动脉瘤特征。它提供了对这些最新临床进展的全面回顾，比较新的和标准的临床实践。在介绍了对腹主动脉瘤的临床认识并探讨了目前的治疗方法后，本文讨论了目前血管内修复术的监测方法，将它们与最近的压力传感技术进行对比。分析了三种用于血管内修复后监测的商用压力感测设备的文献。对评估这些器械安全性和有效性的各种临床前和临床研究进行了综述。提供他们结果的比较摘要。对临床前和临床研究结果的回顾表明，修复后排除的动脉瘤囊血压下降的趋势一致。然而,尽管动脉瘤囊的压力读数成功,尚未建立将这些测量结果转化为是否存在内漏的紧密联系。此外，结果无法确定正在进行的动脉瘤囊生长。因此,对于血管内修复术后内漏和动脉瘤生长的监测,临床仍存在强烈需求.
