The ultrasound triad of fetal hydramnios, abnormal hand posturing, and any other anomaly predicts autosomal trisomy.

摘要: Our definition of hydramnios is an amniotic fluid index 24 cm or greater. We evaluated by ultrasound examination 49 consecutive patients who met this hydramnios. Of these, 22 (44.9%) had anomalies visible ultrasound. The combination hydramnios, abnormal hand posturing, and any other anomaly created a constellation sonographic findings enabling us to predict six specific autosomal trisomies (27.27%): three trisomy 18, two 21, one 13. 27 fetuses with "idiopathic hydramnios" (no identifiable posturing) normal karyotypes. recommend that patient confirmed have detailed experienced sonographer, special attention paid the heart, face, hands. If no abnormality seen hands are normally postured, expectant management may be appropriate. late second- third-trimester fetus displays posturing abnormality, rapid karyotyping funipuncture placental biopsy should recommended facilitate appropriate management.
