Type II endoleak is the most common type of endoleak after endovascular repair of abdominal aortic aneurysm and has been reported in up to 20-50% of patients. Patients undergo lifelong surveillance of aortic graft stents to monitor for endoleak. Contrast-enhanced ultrasound can be an adjunct to CT angiography (CTA) which is the preferred imaging modality for surveillance. However, CT angiography introduces challenges of recurring cost, exposure to ionizing radiation, and the need for iodinated contrast dye. We report a case using CEUS for the detection of type II endoleak.
II型内漏是腹主动脉瘤血管内修复术后最常见的内漏类型，据报道在高达20%-50%的患者中出现。患者需对主动脉移植支架进行终身监测以监测内漏情况。对比增强超声可作为CT血管造影（CTA）的辅助手段，CTA是监测的首选成像方式。然而，CT血管造影带来了重复成本、暴露于电离辐射以及需要使用碘化造影剂等挑战。我们报告一例使用对比增强超声检测II型内漏的病例。
