(EVAR) Endovascular Aneurysm Repair of abdominal aortic aneurysms have mandated the need for surveillance imaging and other follow-up testing to minimize the complications of endograft failure and potential for abdominal aortic aneurysms rupture. The 2-dimensional and 3-dimensional contrast-enhanced computed tomography imaging currently serves as the gold standard for serial (EVAR) Endovascular Aneurysm Repair assessment, but this recommendation is being modified by successful clinical experience using duplex ultrasound, magnetic resonance imaging, and implantable wireless sac pressure sensors. Nearly all stent graft devices and abdominal aortic aneurysm-related complications after (EVAR) Endovascular Aneurysm Repair can be detected using available surveillance modalities assuming a compliant patient during follow-up. Alternating complementary surveillance techniques (contrast and noncontrast computed tomography, ultrasound, and pressure measures) can be used to reduce contrast dye and radiation exposure and can be tailored to patients with chronic renal insufficiency.
腹主动脉瘤的血管内动脉瘤修复术（EVAR）要求进行监测成像和其他随访检查，以尽量减少血管内移植物失败的并发症以及腹主动脉瘤破裂的可能性。二维和三维对比增强计算机断层扫描成像目前是连续血管内动脉瘤修复术（EVAR）评估的金标准，但使用双功超声、磁共振成像和植入式无线囊内压力传感器的成功临床经验正在改变这一推荐。假设随访期间患者配合，几乎所有血管内动脉瘤修复术（EVAR）后的支架移植物装置和腹主动脉瘤相关并发症都可以使用现有的监测方式检测到。交替使用互补的监测技术（对比和非对比计算机断层扫描、超声和压力测量）可以减少造影剂和辐射暴露，并且可以针对慢性肾功能不全患者进行调整。
