Surveillance imaging of type II endoleak with contrast-enhanced ultrasound.
Filip JelenakJaspreet HiraRachita KhotPublished in: BJR case reports (2023)
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.
