A fetal case with midgut volvulus.

A fetus with midgut volvulus is described. The mother had developed polyhydramnios, and the fetus was found by sonography to have dilated fluid-filled structures compressing the chest in the upper abdomen. Percutaneous aspiration of the upper abdominal mass was performed to identify the content and know whether decompressing the chest would be beneficial. The removal of meconium-stained fluid accomplished an improvement of the fetal biophysical profile. The infant was delivered by low transverse cesarean section, and survived with immediate removal of the fluid in the abdominal mass and ventilatory therapy.
