Endoleaks following endovascular aneurysm repair (EVAR) are common and present a diagnostic challenge in the follow-up after EVAR. Contrast-enhanced ultrasound (CEUS) is a promising new method for the diagnosis and follow-up of endoleaks. CEUS with SonoVue allows a rapid and non-invasive diagnosis in the follow-up after EVAR. The sensitivity and specificity of conventional ultrasound compared to the multislice CT angiography is estimated to be 33-63% and 63-93%, respectively. These values can be increased through the use of CEUS in up to 98-100% (sensitivity) and 82-93% (specificity). This article describes the etiology, classification and importance of different types of endoleaks. The value of CEUS in this clinical scenario will be discussed.
血管内动脉瘤修复术（EVAR）后内漏很常见，并且在EVAR术后随访中带来诊断挑战。对比增强超声（CEUS）是一种用于内漏诊断及随访的有前景的新方法。使用声诺维的CEUS可在EVAR术后随访中实现快速且无创的诊断。与多层螺旋CT血管造影相比，传统超声的敏感性和特异性估计分别为33% - 63%和63% - 93%。通过使用CEUS，这些数值可分别提高至98% - 100%（敏感性）和82% - 93%（特异性）。本文描述了不同类型内漏的病因、分类及重要性。将讨论CEUS在这一临床情况中的价值。
