Amniotic band syndrome

What causes amniotic bands?

Amniotic bands are caused by damage to a part of the placenta called the amnion. Damage to the amnion may produce fiber-like bands that can trap parts of the developing baby.

How is amniotic band syndrome diagnosed?

The earliest reported detection of an amniotic band is at 12 weeks gestation, by vaginal ultrasound. On ultrasound the bands appear as thin, mobile lines, which may be seen attached to or around the baby. However these bands may be difficult to detect by ultrasound, and are more often diagnosed by the results of the fusion, such as missing or deformed limbs.

What is the prognosis of amniotic band syndrome?

Because the prognosis of people with amniotic band syndrome can vary from patient to patient, the best person to provide your family with information regarding your child's prognosis, is the health care providers involved in their care. In general, the outlook for infants with a single band involving the superficial skin of the wrist and/or hand is good. While the family and child will need to adjust to the cosmetic difference, the functional use of the hand is normal. Deeper bands can be associated with complications (i.e., blockage of lymph and blood vessels) that can worsen over time and may require surgery. Some people with amniotic band syndrome are born with acrosyndactyly, a fusion of the fingers that may limit the hand function and cause stiffness of the joints. In many cases a good ability to hold and grasp may be obtained with reconstructive procedures.

How might amniotic band syndrome be treated?

Mild cases may not require treatment, however all bands need monitoring as growth occurs to watch for progressive constriction and swelling. Other constrictions may require surgical management; surgical options will vary depending on the abnormality. People with amniotic band syndrome who have amputations may benefit from the use of prosthetics.
