Rezumat: Amniotic bands syndrome (ABS) comprises a group of birth defects, ranging from minor constriction rings with secondary lymphedema to severe abnormalities, particularly complex, due to these intraamniotic structures which adhere, influence and disrupt in varying degrees fetal structures growth and development. Amniotic bands most commonly affects fetal extremities with a higher affinity for distal segments. Constriction rings or skin marking and digital or limb amputation are common findings. ABS diagnosis is possible from 9 weeks of gestation. Amniotic bands can be very difficult to identify on routine ultrasonography, in many cases may remain undiagnosed or underdiagnosed. The term amniotic bands sequence or syndrome describes this obstetric condition as a heterogeneous malformation pattern that can not be related to a single factor, due to its polymorphism of manifestations and fetal prognosis. Ultrasound examination is the standard for diagnosis. Fetal MRI is complementary to ultrasound and may release new perspectives in prenatal diagnosis.
