Amniotic Band Syndrome

Amniotic band syndrome (ABS) occurs when strands of amniotic bands entangle the fetus and restrict blood flow to parts of the developing body, resulting in conditions such as clubfoot or cleft palate.

ABS is diagnosed through ultrasound and prenatal magnetic resonance imaging (MRI) and is typically treated after birth with plastic and reconstructive surgery to correct the deformity.

In rare cases—when a vital organ is affected or a limb is in danger of amputation after birth—we may recommend fetal intervention.
