The North American Fetal Therapy Network (NAFTNet) is a voluntary association of medical centers in the United States and Canada with established expertise in fetal surgery and other forms of multidisciplinary care for complex disorders of the fetus. The goal of NAFTNet is to foster collaborative research in fetal medicine.
Maternal–fetal medicine (MFM), also known as perinatology, is a branch of medicine that focuses on managing health concerns of the mother and fetus prior to, during, and shortly after pregnancy. Maternal–fetal medicine specialists are physicians who subspecialize within the field of obstetrics. [ 1 ]
The scan is obtained with the fetus in sagittal section and a neutral position of the fetal head (neither hyperflexed nor extended, either of which can influence the nuchal translucency thickness). The fetal image is enlarged to fill 75% of the screen, and the maximum thickness is measured, from leading edge to leading edge.
The main source of income of the Charity is a private clinic, and the Fetal Medicine Foundation has donated more than £45 million to finance the training of doctors from around the world and to carry out major multi-centre research studies in fetal medicine. [6] The Fetal Medicine Foundation also organises the yearly World Congress in Fetal ...
Usual follow-up steps include (1) a prenatal ultrasound exam to look for fetal abnormalities and/or (2) measurement of AFP in amniotic fluid obtained via amniocentesis. Maternal serum AFP (MSAFP) varies by orders of magnitude during the course of a normal pregnancy. MSAFP increases rapidly until about 32 weeks gestation, then decreases gradually.
It is closely related to the specialty of maternal-fetal medicine, although obstetric medicine does not directly care for the fetus. The practice of obstetric medicine, or previously known as "obstetric intervention," primarily consisted of the extraction of the baby during instances of duress, such as obstructed labor or if the baby was ...
Fetal antigen status can be tested as early as 15 weeks by PCR of fetal cells. [12] CVS is possible as well to test fetal antigen status but is not recommended. CVS carries a higher risk of fetal maternal hemorrhage and can raise antibody titers, potentially worsening the antibody effect. [12]
This is a major cause of HDN, because 75% of pregnancies result in some contact between fetal and maternal blood, and 15–50% of pregnancies have hemorrhages with the potential for immune sensitization. The amount of fetal blood needed to cause maternal sensitization depends on the individual's immune system and ranges from 0.1 mL to 30 mL. [5]
