The prenatal sonographic diagnosis of fetal finger abnormalities was recorded in a study population of 20,000 pregnant patients. All scans were performed with a vaginal transducer at 13 to 17 weeks' gestation. The following abnormalities were observed: six cases of polydactyly, three of syndactyly, nine cases of overlapping fingers, two cases of cleft hands, two cases of adactyly, one case of aphalangia, and one case of clasped thumb. In 15 of the 25 fetuses with finger abnormalities, we observed associated malformations or chromosomal disorders, or both. We therefore recommend that examination of the fingers and hands should become an integral part of the early ultrasonographic evaluation of the fetus.
在一项针对20000名孕妇的研究中记录了胎儿手指异常的产前超声诊断情况。所有扫描均在妊娠13至17周时使用阴道探头进行。观察到以下异常情况：六例多指畸形、三例并指畸形、九例手指重叠、两例裂手、两例无指畸形、一例无指骨以及一例扣拇畸形。在25例有手指异常的胎儿中，有15例还观察到了相关的畸形或染色体疾病，或两者皆有。因此，我们建议对手指和手部的检查应成为早期胎儿超声评估的一个组成部分。
