Hydrops fetalis (fetal hydrops) is a serious fetal condition defined as abnormal accumulation of fluid in two or more fetal compartments, including ascites, pleural effusion, pericardial effusion, and skin edema. In some patients, it may also be associated with polyhydramnios and placental edema.
Can a baby survive fetal hydrops?
The outlook for hydrops fetalis depends on the underlying condition, but even with treatment, the survival rate for the baby is low. Only about 20 percent of babies diagnosed with hydrops fetalis before birth will survive to delivery, and of those babies, only half will survive after delivery.
Can hydrops resolve?
Spontaneous resolution of Non-immune Hydrops fetalis. A case report of hydrops fetalis characterized by ascites and scalp edema of unknown etiology is described. The hydrops developed at 24 weeks and resolved completely without treatment resulting in a live born infant at term.
How is hydrops Fetalis treated?
Treatment for a newborn may include: For immune hydrops, direct transfusion of red blood cells that match the infant’s blood type. An exchange transfusion to rid the baby’s body of the substances that are destroying the red blood cells is also done.
How early can fetal hydrops be detected?
With recognition of early hydrops through increased use of both first-trimester dating ultrasound and routine ultrasound screening at 18–22 weeks, the incidence may be higher. Finnish data from women undergoing routine anomaly screening at 20 weeks’ gestation gives an incidence of 1 in 1700.
Is hydrops genetic?
Thirty (5.5%) and 35 (2.8%) cases of hydrops were found in the groups of fetal and neonatal autopsies, respectively. Genetic causes accounted for 35%. A careful search for previously reported genetic causes of fetal hydrops indicated 64 different etiologies.
What is mirror syndrome in pregnancy?
Mirror syndrome (MS) is a rare complication of fetal hydrops appearing as a triple edema (fetal, placental as well as maternal) , in which the mother “mirrors” the hydropic fetus. This syndrome was first described in 1892 by the Scottish obstetrician John William Ballantyne .
What causes non immune hydrops?
Non-immune hydrops, the most common type, is caused by a fetal medical condition or birth defect that affects the body’s ability to manage fluid.
What does hydrops mean?
Medical Definition of hydrops
1 : edema. 2 : distension of a hollow organ with fluid hydrops of the gallbladder.
Why is hydrops Fetalis incompatible with life?
The severest form is Hb Barts hydrops fetalis syndrome, due to loss of all 4 genes, which is generally incompatible with life.
What causes fluid around lungs in unborn baby?
Fetal pleural effusion is an accumulation of fluid in the chest cavity of a developing fetus. As the fluid increases, it can compress the developing lungs and heart. The underlying cause of pleural effusion in a fetus may include genetic issues, infection, and heart or lung conditions.
How do fetus get fluid in their lungs?
In the womb, the baby’s lungs are filled with fluid. This is normal and healthy. During labor, your baby’s body releases chemicals to help their lungs push out the fluid. The pressure of the birth canal on your baby’s chest also releases fluid from their lungs.
What causes extra fluid behind neck in fetus?
More fluid than normal in the back of the neck means there is a higher risk for Down syndrome, trisomy 18, trisomy 13, Turner syndrome, or congenital heart disease. But it does not tell for certain that the baby has Down syndrome or another genetic disorder. If the result is abnormal, other tests can be done.
How common is fetal pericardial effusion?
Aetiopathogenesis. Pericardial effusion can be found isolated or associated with different abnormalities described in the literature (Table 1). The incidence is about 0.64–2.00%. It is necessary to perform a comprehensive fetal study ultrasound to rule out the different causes to which it is associated.
What causes pericardial effusion in fetus?
The most common cause of a fetal pericardial effusion was heart failure (13 fetuses). Fetal renal cystic dysplasia with oligohydramnios and other anomalies was present in six fetuses. Four of this group had microscopic evidence of pericarditis on postmortem examination.
What does too much fluid around the baby mean?
Polyhydramnios is the medical term for having too much amniotic fluid in the womb. It has several possible causes, including maternal diabetes, multiple pregnancies, or abnormalities in the fetus. In some cases, doctors are unable to identify the cause.
