No other fetal abnormalities were seen. 3DUS was performed using a multifrequency volumetric transducer (Accuvix V20; Samsung Medison, Seoul, Korea) and clearly showed the spatial relationship between the bands and the body of the fetus, thus proving that the bands had really adhered to the forearm, but without strangling it [Figure 2].
