Frequency of fetal anomalies in Sonographically determined polyhydramnios.
Pak Postgrad Med J Jan ;13(1):28-31.

Aim of this study was to determine the frequency of fetal anomalies in sonographically detected polyhydramnios. One hundred pregnant women in 2nd and 3rd trimester who met the criteria of having sonographically determined amniotic fluid pocket depth of 8cm or greater were included in this study and were labeled as polyhydramniotic. The measurements were made to the nearest 0.5cm and then ranked in 2cm incremental groups from 8.0cm upwards. The degree of polyhydramnios according to pocket depth was correlated directly that an anomaly would be seen. Out of the 100 patients 96% were with singleton pregnancy and 4% were with twin pregnancy. The results showed that as the size of amniotic fluid pocket increased so did the frequency of fetal anomalies. So this study convincingly proves that increasing degree of polyhydramnios as determined by an appropriate criteria with sonography is associated with increasing frequency of fetuses with anomalies.
