Deformations of the extremities with limb reduction are rare congenital defects which affect one in 1692 live babies. Three-dimensional ultrasound can be of value in the prenatal diagnosis of such deformities. We present a case of upper phocomelia and congenital thrombocytopenia (TAR syndrome). Visualization of the upper extremities was achieved by three-dimensional ultrasound after surface and volume rendering. This new technique allows imaging not only of surfaces like the fetal skin, but also of internal structures like the fetal skeleton.
肢体短小所致的肢体畸形是一种罕见的先天性缺陷，每1692例活产婴儿中就有1例受其影响。三维超声在这类畸形的产前诊断中具有重要价值。我们报告一例上肢海豹肢畸形并先天性血小板减少症（TAR综合征）的病例。通过表面和容积再现技术，利用三维超声实现了上肢的可视化。这项新技术不仅能够对胎儿皮肤等表面进行成像，还能对胎儿骨骼等内部结构进行成像。
