Summary
This study will be a cross-sectional survey of interobserver variability associated with
contrast enhanced ultrasound (CEUS) to detect endoleaks using computed tomographic
angiography (CTA) as the practice standard. The investigators will enroll 40 consecutive
patients undergoing endovascular abdominal aortic aneurysm repair (EVAR). At the first
follow-up visit after the procedure, participants will undergo two abdominal ultrasound
examinations with and without contrast, and one CTA. Analyses will be conducted to examine
interobserver variability in the detection and characterization of endoleaks using
contrast-enhanced ultrasound (CEUS). Other endpoints include examination of sensitivity and
specificity of CEUS compared to CTA, and characterization of the number and types of
endoleaks detected.
