What this Trial Is About
This prospective observational study evaluates the efficacy of contrast-enhanced ultrasound and biomarker determination in the follow-up of patients with abdominal aortic aneurysm (AAA) treated with Endovascular Aneurysm Repair (EVAR). Currently, computed tomography angiography (CTA) is the standard for follow-up, although it has disadvantages such as radiation exposure and the use of iodinated contrasts. Contrast-enhanced ultrasound (CEUS), free of radiation and nephrotoxicity, and biomarkers could reduce the need for CTA minimizing the associated risks. Biomarkers will be measured before and after EVAR and CEUS will be performed at various time points and compared with CTA results to validate concordance and effectiveness in detecting endoleaks and aneurysm remodeling. The objectives include determining the efficacy of these combined methods and establishing a follow-up protocol that reduces exposure to radiation and iodinated contrast agents.
