membrane separation
Iatrogenic separation of chorion and amnion layers, a potential complication of fetal surgical procedures.
Full Definition
Membrane separation refers to the iatrogenic division of the normally fused chorion and amnion layers during fetal surgical procedures requiring hysterotomy or large trocar insertion. This complication can create a potential space between the membrane layers, leading to amniotic fluid leakage into the extraamniotic space and subsequent oligohydramnios. Membrane separation increases the risk of preterm rupture of membranes and preterm labor. Prevention involves careful surgical technique and gentle handling of membranes during closure.
Usage
Usage note: Distinguish from spontaneous membrane rupture by noting the iatrogenic nature and typical location at surgical sites.
