What are congenital anomalies and how can they be detected?
Congenital anomalies are structural or functional abnormalities that occur during intrauterine development. They can be detected through various prenatal screening methods such as ultrasound, amniocentesis, and chorionic villus sampling (CVS). Early detection allows for better management and planning for potential interventions post-birth. Some common congenital anomalies include heart defects, neural tube defects, and Down syndrome.
