Prenatal diagnosis and pregnancy outcomes in fetuses with vertebral abnormalities

Invasive prenatal diagnosis is recommended for all fetuses diagnosed with VA, regardless of whether associated anomalies are present. WES can enhance the diagnostic yield for fetuses with negative CMA results. Fetuses with isolated VA can have favorable pregnancy outcomes when genetic testing results are negative. However, long-term follow-up remains necessary for the assessment of the prognosis of these fetuses.
