Cystic hygroma can be associated with a nuchal lymphangioma or a fetal hydrops. [4] Additionally, it can be associated with Down syndrome , Turner syndrome , [ 5 ] or Noonan syndrome . If it is diagnosed in the third trimester, then chances of association with Down syndrome are increased, but if diagnosed in the second trimester, then it is ...

The newer integrated screen (formerly called F.A.S.T.E.R for First And Second Trimester Early Results) can be done at 10 plus weeks to 13 plus weeks with an ultrasound of the fetal neck (thicker nuchal skin correlates with higher risk of Down syndrome being present) and two chemicals (analytes), pregnancy-associated plasma protein A and human ...
The pregnancy outcome is strongly chromosome specific. The most frequently seen trisomic cells in confined placental mosaicism involve chromosomes 2, 3, 7, 8 and 16. The next frequently involved are 9, 13, 15, 18, 20 and 22. [8] It has been observed that CPM involving the sex chromosomes usually has no adverse effects on fetal development. [9]
The cave of septum pellucidum (CSP), cavum septi pellucidi, or cavity of septum pellucidum is a slit-like space in the septum pellucidum that is present in fetuses but usually fuses during infancy. The septum pellucidum is a thin, laminated translucent vertical membrane in the midline of the brain separating the anterior horns of the right and ...
45,X/46,XY mosaicism, also known as X0/XY mosaicism and mixed gonadal dysgenesis, [1] is a mutation of sex development in humans associated with sex chromosome aneuploidy and mosaicism of the Y chromosome. It is a fairly rare chromosomal disorder at birth, with an estimated incidence rate of about 1 in 15,000 live births. [2]
Fetoscopy is an endoscopic procedure during pregnancy to allow surgical access to the fetus, the amniotic cavity, the umbilical cord, and the fetal side of the placenta. A small (3–4 mm) incision is made in the abdomen , and an endoscope is inserted through the abdominal wall and uterus into the amniotic cavity.
