[New aspects in the diagnosis of fetal malformations using ultrasound].
The article deals with new ultrasound diagnostic aspects of foetal malformations. The frequency of such events in Yugoslav population is described and importance of their early detection is emphasized. The following features of foetal malformations are discussed: systems, characteristics, possible aetiopathogenesis, ultrasound detection and sonographic signs. Some congenital malformations are illustrated by original ultrasound and postnatal pictures. Their postnatal and intrauterine corrections are examined. Consequently, the optimal possible abortion is discussed. The analysis concerns the practical classification of congenital malformations into serious, incorrectable, incompatible with life, recommendation for abortion, and into light, correctible anomalies. Exclusion of pathologic events in risk-groups and during routine practice is emphasized. Possible errors (false-positive and false-negative diagnosis) and difficulties in the definition of small structural anomalies are presented. Complementary diagnostical methods are also enumerated.
