Endovascular aortic aneurysm repair (EVAR) is evolving into a viable alternative to open surgical repair for many patients with abdominal and thoracic aortic aneurysms. Endoleak development is a complication of EVAR and represents one of the limitations of this procedure. Endoleaks represent blood flow outside the stent-graft lumen but within the aneurysm sac. Lifelong imaging surveillance of patients after EVAR is critical to detect endoleaks for the patient's benefit and to determine the long-term performance of the stent-graft. Although computed tomographic angiography is the most commonly used examination for imaging surveillance, magnetic resonance angiography, ultrasonography, and digital subtraction angiography all have a role in endoleak detection and management. This review will focus on imaging techniques used for endoleak detection and the role imaging surveillance plays in the overall care of the post-EVAR patient.
对于许多患有腹主动脉瘤和胸主动脉瘤的患者而言，血管内主动脉瘤修复术（EVAR）正逐渐成为开放性手术修复的一种可行替代方案。内漏的发生是EVAR的一种并发症，也是该手术的局限性之一。内漏是指支架移植物管腔外但动脉瘤腔内的血流。EVAR术后对患者进行终身影像学监测对于检测内漏以造福患者以及确定支架移植物的长期性能至关重要。尽管计算机断层血管造影是影像学监测最常用的检查方法，但磁共振血管造影、超声检查和数字减影血管造影在内漏的检测和管理中都发挥着作用。本综述将聚焦于用于内漏检测的成像技术以及成像监测在EVAR术后患者整体护理中的作用。
