Contrast-Enhanced Ultrasound Surveillance Following Endovascular Aneurysm Repair

Endovascular aneurysm repair (EVAR) has become the standard of care for many patients with abdominal aortic aneurysms. This lecture will address how contrast-enhanced ultrasound is an effective diagnostic tool for surveillance and follow-up to detect and classify endoleaks following EVAR. 

Original Release Date: December 2020
Review Date: October 2021, February 2022, February 2023

Target Audience

Cardiologists, vascular surgeons, interventional radiologists, echocardiography, respiratory therapists (direct delivery), pharmacists, nurses, nurse practitioners, physician assistants and noninvasive vascular testing specialists and sonographers. 

Learning Objectives

  • Explain the fundamental physics of contrast-enhanced ultrasound.
  • Apply proper use of contrast enhancement agents for EVAR.
  • Describe the pathophysiology of EVAR endoleaks.
  • Detect EVAR endoleaks on contrast-enhanced ultrasound.
  • Characterize enhancement of different types of EVAR endoleaks.
