Three-dimensional (3D) power Doppler sonographic imaging provides a 3D view of the blood vessels. This technique reportedly has advantages over other forms of sonography in visualizing normal and abnormal fetal vascular anatomy. We report the case of a 36-year-old pregnant woman in whom 3D power Doppler sonography with simultaneous gray-scale imaging was performed at 32 weeks' gestational age to investigate an intestinal obstruction in the fetus that was suspected on the basis of 2-dimensional sonographic findings. The 3D sonograms revealed that the superior mesenteric artery and vein of the fetus were wound counterclockwise, forming the "barber-pole" sign. At 38 weeks' menstrual age, the female infant was delivered vaginally. Only duodenal atresia and annular pancreas, but not intestinal malrotation, were found postnatally. Surgical reconstruction of the duodenum was performed, with no major complications. Previous research suggests that the counterclockwise barber-pole sign is a normal finding. On the basis of our case, we believe that this "negative finding" might be used to exclude the diagnosis of midgut volvulus, a condition that would be expected to cause these vessels to wrap around in a clockwise direction. |
