产科已大量应用经阴道声学摄影检查正常和异常的早期妊娠。现在能用经阴道的高频探头声学摄影在孕早期或早中期诊断胎儿畸形,因而对严重畸形胎儿能较早地、安全地终止妊娠,现首先报告经阴道声学摄影在孕14周时诊断前脑无叶无裂畸形:患者初孕妇,25岁,既往无特殊病史。孕7周时经阴道声学摄影提示为宫内孕,有心跳,顶-臀长1.0cm(=7孕周)。孕14周时经阴道声学摄影提示为单脑室,丘脑融合并有形似半月体的额皮质,提示
Obstetricians have extensively applied transvaginal acoustic photography to examine normal and abnormal early gestational age. Transvaginal high-frequency transducer acoustic photography can now be used to diagnose fetal malformations early in pregnancy or early and mid-term, and thus severe malformation fetus can terminate the pregnancy earlier and safely, the first report of transvaginal acoustic photography at 14 weeks of pregnancy before diagnosis No leaf no splitting deformity: early pregnant women, 25 years old, no previous history of a particular medical history. Transvaginal acoustic photography at 7 weeks of gestation suggests intrauterine pregnancy with a heartbeat, apex-buttock length of 1.0 cm (= 7 gestational weeks). Transvaginal acoustic photography at 14 weeks of gestation prompts single-ventricle thalamic fusion with a hemobasal frontal cortex, suggesting
