Case report

A 19-year-old woman (G3P1) presented to our department at 26 weeks of her pregnancy. Her first trimester screening was normal. Our ultrasound examination discovered an intraamniotic synechia, polyhydramnios, interventricular septal defect of the fetus.
Serial amnioreductions had been performed at 27, 30, 31 and 34 weeks of the pregnancy (overall 6 liters of the amniotic flow was obtained). After the 31st week’s amnioreduction we could observed amnionic sheets floating within the amniotic fluid, concordant with the amniotic rupture. The sheets of the ruptured amnion didn’t have any contact with the fetus.
The neonate was delivered at 37 weeks (2450 g, 50 cm), but she died one day later. Religious rea-sons led parents not to agree with further study of the neonate, but the postnatal appearance of the placenta and amniotic sheets confirmed the diagnosis of the amniotic rupture.

Images 1, 2: The image 1 shows a ventricular septal defect of the fetal heart. The image 2 shows a sheet of the amnion within the amniotic fluid.

Images 3, 4, 5, 6, 7, 8, 9, 10: The images show several scans of the amniotic sheets within the amniotic fluid after the rupture of the amnion. At some images the sheets of the ruptured amnion are signed by arrows.

Images 11, 12, 13: The images show postnatal appearance of the placenta and amniotic sheets after the prenatal rupture of the amnion.
