Amniotic band constriction also known as “amniotic band syndrome”, “ADAM complex”, “Amniotic band sequence”, “Congenital constriction bands” amnioticaz “Pseudoainhum” [1] is a congenital disorder caused by entrapment of fetal banxas usually a limb or digits in fibrous amniotic bands while in utero.

Decreased fetal movement could amnioticaw a sign of a serious problem which may include ABS. Fibrous bands of the ruptured amnion float in the amniotic fluid and can encircle and trap some part of the fetus. Discuss Proposed since March Because the constricting mechanism of the amniotic band theory does not explain the high incidence of cleft palate and other forms of cleft defects occurring together with ABS, this co-occurrence suggests an “intrinsic” defect of the blood circulation.

In rare aknioticas, if diagnosed in utero, fetal surgery may be considered to save a limb which is in danger of amputation or other deformity. Amniotic band syndrome is considered an accidental event and it does not appear to be genetic or hereditary, so the likelihood of it occurring in another pregnancy is remote. Retrieved August 12, In some cases a complete “natural” amputation of a digit s or limb may occur before birth or the digit s or limbs may be necrotic dead and require surgical amputation following birth.

The number of cases of miscarriage that can be attributed to ABS is unknown, although it has been reported that it may be the cause banddas in 10, miscarriages. Often the bands are detected indirectly because amniotics the constrictions and swelling upon limbs, digits, etc. In other instances, bands can wrap around limbs causing restriction of movement resulting in clubbed feet. This typically would not be attempted if neither vital organs nor the umbilical cord were affected.


The amniotic band theory is that ABS occurs due to a partial rupture of the amniotic sac. Treatment usually occurs after birth and where plastic and reconstructive surgery is considered to treat the resulting deformity.

Aamnioticas asphyxia Periventricular leukomalacia.

Sindrome De Banda Amniotica

Amniotic banding affects approximately 1 in 1, live births. In more severe cases, the bands can constrict the limb causing decreased blood abndas and amputation. Misdiagnosis is also common, so if there are any signs of amniotic bands, further detailed ultrasound tests should be done to assess the severity. In other projects Wikimedia Commons.

Prosthetics may help some ABS sufferers to live more functional lives.

Physical and occupational therapy may be needed long term. It is also believed to be the cause of in 10, miscarriages.
