The signs of ABS vary depending on when the damage to the amniotic sac occurs, as well as which of the baby's body parts are constricted by the amniotic bands.
What are the complications of ABS?
Amniotic bands, when wrapped around your baby's body parts, can cause limb deformities such as:
- Stunted growth of fingers and toes
- Webbed toes or fingers
- Cleft palate
In the most severe cases, amniotic bands cause organ damage or loss of pregnancy.
What is the long-term outcome for babies with amniotic band syndrome?
The outcome depends on many variables, including:
- Timing of the amnion's rupture during pregnancy
- Location of the band constriction
- If and when the condition is diagnosed (usually through an ultrasound or at birth)
- The severity of the damage caused by band constriction
All cases of amniotic band syndrome have PPOROM (Preterm Premature Rupture of Membranes) and the average gestational age delivery is 32 weeks.
But there is good news! Early diagnosis at specialist clinics like the Colorado Fetal Care Center can potentially save a baby's life or limbs.
How is ABS diagnosed in utero?
Most amniotic bands are found during routine ultrasound between 6 and 18 weeks of pregnancy. However, if a band is visualized on ultrasound, it does not automatically mean that your baby has suffered damage.
If ABS is diagnosed, the team at the Colorado Fetal Care Center gets to work creating a care plan tailored to your baby's specific case. Sometimes, prenatal surgery is recommended to prevent or decrease complications from amniotic bands. In cases of ABS that do not threaten life or limb, postnatal surgery might minimize or reverse the effects of birth defects once a baby is born.
