The value of contrast-enhanced ultrasonography in evaluating abdominal aneurysm and comparison by CT angiography

Objective To compare the capability of contrast-enhanced ultrasonography (CEUS) and CT angiography(CTA)in evaluating abdominal aortic aneurysm. Methods Both CEUS and CTA examinations were performed in 18 patients (diagnosis before surgery in 10 patients, surveillance after surgery in 8 patients). The CEUS contrast agent was Sonovue. The diagnosis and the appearance about abdominal aortic aneurysm, dissecting aortic aneurysm, aortic pseudoaneurysm and the image after operation were compared. Results There were abdominal aortic aneurysm in 5 patients, dissecting aortic aneurysm in 4 patients and aortic pseudoaneurysm without operation in 1 patient. The 8 patients under surveillance after operation including endovascular abdominal aortic aneurysm repair in 4 patients and open repair with artificial vascular in 4 patients. Both CEUS and CTA had the same results. Conclusion The CEUS is comparable to CTA in diagnosing abdominal aortic aneurysm. The CEUS is worthy of application in abdominal aortic aneurysm.
