[The fetus with a digestive, pulmonary or urinary tract malformation diagnosed by ultrasonography. Management].

Ultrasound diagnosis of a fetal visceral malformation raises many questions concerning both medical and ethical aspects. Are there associated malformations or chromosomal anomalies? Is the malformation compatible with life. What will be the quality of survival after birth? Is there efficient surgical treatment? Is it possible to maintain the pregnancy until term or must we consider a premature delivery or an interruption of pregnancy? The decisions are difficult and they necessitate co-operation between the different specialists involved with the antenatal and immediate postnatal care of the fetus. In this paper the authors analyse the various situations that may be encountered depending upon the type of digestive, pulmonary or urinary tract fetal abnormality (cardiac or cerebral malformations have been excluded).
