NCARDRS Congenital Anomaly Official Statistics Report, 2021

Some types of congenital anomaly are more likely to be detected antenatally than others. Figure 6 shows that anomalies such as abdominal wall (96.3%), nervous system (88.1%) and kidney and urinary anomalies (85.3%) are the 3 conditions most frequently identified antenatally. Genital anomalies are unlikely to be identified antenatally.

Individual anomalies within these subgroups may not follow these patterns. Babies with more than one anomaly will be represented in each applicable bar. A more detailed breakdown by specific congenital anomaly, including the number of babies reported, is available in Data table 6.
