• Objective: This study aimed at examining the detection rate of congenital abnormalities by using routine ultrasonography at 18–22 weeks of gestation. Methods: The sample included 7,236 fetuses. A detailed sonographic examination was performed in each fetus and a neonatal evaluation or pathology examination was made to confirm the prenatal findings. Results: The total prevalence of fetal abnormalities in our sample was 2.24% (162/7,236). There were 29/162 (17.9%) fetuses with CNS abnormalities, 27/162 (16.7%) fetuses with gastrointestinal abnormalities, and 28/162 (17.3%) fetuses with urinary tract abnormalities. There were also 31/162 (19.1%) fetuses with cardiovascular abnormalities, 26/162 (16.0%) with malformation of the limbs and musculoskeletal system, and 21/162 (13%) fetuses with other various abnormalities. The overall sensitivity in detecting fetuses with congenital abnormalities was 80.25% (130/162). The sensitivity per system was 93.1% (27/29) for CNS, 45.2% (14/31) for cardiovascular system, 85.2% (23/27) for gastrointestinal system, 85.7% (24/28) for urinary system, 84.6% (22/26) for musculoskeletal system, and 95.2% (20/21) for the rest of the abnormalities detected. We performed 40 pregnancy terminations in the group of malformed fetuses. Among the fetuses considered as normal, 1.7% had chromosomal abnormalities. Conclusions: The results indicate that routine sonographic examination at 18–22 weeks of gestation can detect the majority of congenital abnormalities. More experience is needed for the examination of the cardiovascular system, where the sensitivity was particularly low (14/31 or 45.2%). J. Matern.‐Fetal Med. 1999;8:64–69. © 1999 Wiley‐Liss, Inc.
