Abstract: Objective To explore oral contrast-enhanced ultrasonography findings in superior mesenteric artery syndrome (SMAS).Methods Twenty-nine patients with SMAS were examined using oral contrast-enhanced ultrasonography,which was confirmed by contrast-enhanced spiral computerized tomography.Results Abdominal ultrasonography with oral contrast-enhanced ultrasonography revealed a significant reduction of the SMA angle and diminished SMA-aorta distance in 29 subjects.Duodenum was showed the indentation and funnel shaped or dumbbell shaped findings which was caused by pressure of the SMA in patients with recumbent position.The proximal part of duodenum expanded distinctively with contrast media movement fro.Ultrasonography and CT examinations had a good agreement in diagnosing pathological aortomesenteric angle and distance.Conclusions Oral contrast-enhanced ultrasonography presents characteristic findings in patients with SMAS,which is useful in epidemiological screening of suspicious cases of SMAS in children.
