Fetoscopic surgery in amniotic band syndrome: report of the first successful case in Peru with postnatal correlation at 6 and 12 months of life

Amniotic band syndrome (ABS) or amniotic band disruption complex is a congenital malformation that occurs because of amniotic flanges of heterogeneous etiology, pathogenesis that involves a series of fetal clinical manifestations, such as constriction, amputation, and multiple craniofacial, visceral and wall defects. The estimated prevalence of ABS ranges from 1:15.000 to 1:1.200 liveborn. It affects both sexes equally. Prenatal diagnosis may be suspected as early as the late first trimester when ultrasound imaging detects constriction rings, limb amputations and/or craniofacial defects. Prenatal therapy may offer an alternative treatment with release of constriction rings through fetoscopy in those fetuses that would benefit from the procedure.
