Three-dimensional ultrasound in prenatal counselling of congenital talipes equinovarus.

The fetus of a 35-year-old woman, gravida 5, para 3, was diagnosed with isolated left-sided congenital talipes equinovarus on routine ultrasound at 22 weeks of gestation. Parents were counselled about the abnormality but still ultrasound pictures made it difficult for them to understand the nature of the defect. A three-dimensional ultrasound scan helped the couple to understand the abnormality, make an informed choice-with self-confidence-regarding pregnancy continuation, and plan for postnatal management.
