amniotic membrane
Inner layer of fetal membranes that must be carefully managed during fetal surgical procedures to prevent rupture.
Full Definition
The amniotic membrane is the innermost layer of the fetal membranes, consisting of a thin, avascular tissue that directly contacts the amniotic fluid. During fetal surgery, preservation of membrane integrity is crucial to maintain amniotic fluid volume and prevent complications such as oligohydramnios, infection, and preterm labor. Surgical techniques include careful membrane approximation and use of tissue sealants.
