Neonatal midgut volvulus: Spectrum of findings at color Doppler sonography

ObjectiveThis study was conducted to evaluate the spectrum of findings of neonatal midgut volvulus by color Doppler sonography.Patients and methodsFrom March 2010 to December 2013, fourteen neonates was retrospectively analyzed and diagnosed as midgut volvulus. The clinical and radiological data were evaluated with special concern about the color Doppler sonography findings. The radiological data were correlated with surgical diagnosis.ResultsColor Doppler sonography found proximal bowel dilatation in 8 cases, SMA/SMV inversion of relationships in 12 cases, whirlpool sign in 13 cases and SMV dilatation was found in 10 cases. US sensitivity was 92% to diagnose midgut volvulus.ConclusionUltrasonography is an ideal examination for diagnosis of midgut volvulus and should be performed early in neonates with bilious vomiting.
