Doctors caution, though, that fetal procedures must be done only for conditions that would be fatal or severely disabling, because operating exposes both mother and fetus to all the usual hazards of surgery and anesthesia, plus the risk of early labor and the physical and developmental problems of prematurity.
Chorioamniotic membrane separation and preterm premature rupture of membranes are known complications of invasive fetal procedures.
Despite their relative frequency associated with fetal procedures, few data exist regarding risk factors that may be attributed to their occurrence or the natural history of pregnancies that are affected with chorionic membrane separation or preterm premature rupture of membranes related to the procedure.
As soon as possible after expulsion (less than 6 hours), the brain was removed using the standard fetal autopsy procedure (Valdes-Dapena, 1983), embedded as a whole in OCT compound (Sakura), and snap-frozen in a 2-methylbutane on dry ice bath.
These technologies may permit successful fetal surgical procedures.
This condition can now be effectively treated through the use of fetal laparoscopic procedures, but the potential for lifelong morbidity related to this condition during development is apparent.
Costs for treatment related expenses will include direct medical costs, such as fetal monitoring procedures, equipment, mode of birth and postnatal stay.
Several methodological factors may contribute to differences across study outcomes, such as the route of administration, test substance purity, test species or strain, timing of dosing or fetal evaluation, procedures used in dissecting and examining fetal hearts, statistical approaches applied to data evaluation, and generally uncharacterized interlaboratory variation.
Placental maturity staging is a challenging task due to complex imaging procedure, fetal and gestational age variations.
Details on fetal cadavers, histological procedure, fetal data, and original images can be found therein.
