The use of dynamic computed tomography angiography (dCTA) for the detection of endoleaks in patients who underwent endovascular repair of abdominal aortic aneurysms is gaining interest. This study aims to provide an overview of the current applications of dCTA technologies in vascular surgery. : We performed a comprehensive review by searching in the PubMed database and Cochrane Library (last search: 1 November 2024). We included studies considering endoleak investigation after endovascular aneurysm repair (EVAR). We included papers that reported the outcome of applications of dCTA, excluding case reports or very limited case series (≤4). Finally, 14 studies regarding 377 computed tomography angiographies (CTA) were included and evaluated. : Persistent perfusion of the aneurysm sac is the most common complication after EVAR. Imaging-based surveillance post-EVAR is essential with the aim of early detection, characterization, and localization of endoleaks to guide therapeutic intervention or follow-up. dCTA detected 36 type I endoleaks versus 16 identified with standard CTA and 138 versus 95 type II endoleaks. The emergence of dCTA offers a promising solution through enhanced temporal resolution, allowing the visualization of real-time flow dynamics within the aneurysmal sac essential to establishing endoleak treatment or post-EVAR follow-up.
动态计算机断层血管造影（dCTA）用于检测接受腹主动脉瘤血管内修复术患者的内漏，正日益受到关注。本研究旨在概述dCTA技术在血管外科中的当前应用情况。：我们通过在PubMed数据库和Cochrane图书馆中检索进行了全面综述（最后一次检索时间：2024年11月1日）。我们纳入了考虑血管内动脉瘤修复（EVAR）后内漏调查的研究。我们纳入了报告dCTA应用结果的论文，排除了病例报告或非常有限的病例系列（≤4例）。最后，纳入并评估了14项关于377次计算机断层血管造影（CTA）的研究。：动脉瘤囊持续灌注是EVAR后最常见的并发症。基于影像学的EVAR术后监测对于早期检测、鉴别和定位内漏以指导治疗干预或随访至关重要。dCTA检测到36例假性动脉瘤I型内漏，而标准CTA检测到16例；检测到138例假性动脉瘤II型内漏，而标准CTA检测到95例。dCTA的出现通过提高时间分辨率提供了一个有前景的解决方案，能够可视化动脉瘤囊内的实时血流动力学，这对于确定内漏治疗或EVAR术后随访至关重要。
