[Obstetrical complications due to malformations of the uterus].

In a series of 17 670 deliveries, uterine malformations were seen in 47 cases (0,20%). This level was high bearing in mind the resultant obstetric complications: breech presentation in 51,4% of cases (as against 3,01% for all patients) and a 63,7% caesarian section rate. Maternal morbidity and perinatal mortality could be reduced if obstetricians took care to seek such malformations. The diagnosis would be facilitated by routine measurement of serum cystine-aminopeptidase levels.
