Abstract

BACKGROUND: Computed tomographic angiography (CTA) is routinely used in the monitoring of patients after endovascular repair of abdominal aortic aneurysm. The aim of the study was to determine if contrast-enhanced ultrasonography (CEUS) provides equivalent results to CTA in detection of endo-leaks in patients after abdominal aortic stentgraft placement.
MATERIAL AND METHODS: In a group of 7 patients (6 men and 1 woman; aged 71±7 years) after repair procedure, 16 CTA and 16 CEUS follow-up examinations were performed. Second-generation contrast agent (Sonovue) and low-mechanical index technique were used for ultrasonography imaging.
RESULTS: Computed tomographic angiography showed seven cases of type I, five cases of type II, and no endo-leaks in four examinations. In 15 out of 16 studies, the results of CEUS were consistent with the results of CTA. In one discrepant study, type II endo-leak was detected with CEUS while CTA was negative.
CONCLUSIONS: Contrast-enhanced ultrasonography and CTA examinations in patients after endovascular repair of abdominal aortic aneurysm provide comparable results. CEUS may be considered an alternative technique to CTA.
