Amniotic Band Syndrome (ABS) or amniotic band constriction is a condition occurs during pregnancy, in which the fetus gets entangled with strings of amniotic bands. Growth and development of the fetus gets hampered, as ABS restricts blood supply to some of the body parts. Sometimes, it also results in congenital deformities such as foot, toe, finger, facial, arm and head.
The disease is very rare and occurs in 1 out of 1000-2000 births. If untreated, ABS may result in several severe deformities in the baby. Hence should be diagnosed as early as possible.
What Causes Amniotic Band Syndrome:
Causes behind ABS are not very well known, though doctors believe that it starts with rupture of amnion in the early stages of pregnancy.
- In ABS condition, amnion bands encircle the fetus.
- Amnion rupture appears random and has got no relation with the mother or pregnancy.
- In case it has occurred in later phases of pregnancy, it generally does not occur again.

Managing ABS In Pregnancy:
Your doctor will closely monitor your condition and suggest best possible solution to prevent chances of any progressive injury. Here is how ABS is treated and managed in pregnancy:
- In cases, the band is touching the baby anywhere and not causing any injury, surgery is not suggested in those cases.
- If the band threatens life of the baby and is causing severe facial problems or deformities, a fetoscopy surgery is suggested.
- In course of the surgery a telescope of a pencil size is inserted inside the uterus of the mother. The amniotic band is then cut with the help of laser. This helps in reducing pressure and allows the fetus to develop normally.
- You can always enhance your knowledge by getting into discussions with your doctor. This way you can decide what suits you and your family the best.
