Ultrasound diagnosis and perinatal management of surgically correctable fetal malformations.
Among 276 fetal malformations detected during the nine year period there were 97 potentially correctable anomalies which are described in detail as are the antenatal and postnatal corrective procedures undertaken. On 35 hydrocephalic fetuses 9 were operated upon postnatally in the last 2 yr. Three months after the operation four of the babies were found to be developing normally, three moderately well while two were severely retarded. Two out six babies with cystic hygroma were successfully operated after birth and their development is now normal. Of 23 malformations of the gastro-intestinal tract (two diaphragmatic hernias, three esophageal, four duodenal and four jejunal atresias, seven omphalocele, three gastroschisis) 13 babies were successfully operated and are developing normally. In 8 out of 10 antenatally detected cases of obstructive uropathy antenatal intervention was undertaken. In one case a shunt catheter was inserted for the last three weeks before delivery. Puncture and urine evacuation was performed in seven of the babies. Five were live born and surgical correction was successfully undertaken after birth, while two died (one multiple malformations and the other respiratory distress syndrome). After excluding multiple and chromosomal anomalies the best results are obtained in the correction of gastro-intestinal tract atresia (9 of 11) and obstructive uropathy (5 of 7), where once a passage has been established the baby develops normally. Interventions such as shunts in hydrocephalic babies are always a matter for discussion in relation to the final outcome, but when there is no other choice, this too is a way of endeavouring to help such a baby. Early antenatal diagnosis is therefore extremely important when interruption of pregnancy is still feasible. In cases of malformations detected at a later gestational age early diagnosis facilitates the assessment of the development of the affected organ, possible timely antenatal correction, team consultation regarding the time and mode of delivery and preparations for postnatal correction. Such an antenatal approach makes it possible to significantly influence the perinatal outcome.
