Polyhydramnios is a medical condition describing an excess of amniotic fluid in the amniotic sac.It is seen in about 1% of pregnancies. [1] [2] [3] It is typically diagnosed when the amniotic fluid index (AFI) is greater than 24 cm. [4] [5] There are two clinical varieties of polyhydramnios: chronic polyhydramnios where excess amniotic fluid accumulates gradually, and acute polyhydramnios ...

Post-maturity syndrome is the condition of a baby born after a post-term pregnancy, first described by Stewart H. Clifford in 1954. [1] Post-maturity refers to any baby born after 42 weeks gestation, or 294 days past the first day of the mother's last menstrual period.
An obstetric labor complication is a difficulty or abnormality that arises during the process of labor or delivery.. The Trust for America's Health reports that as of 2011, about one third of American births have some complications; many are directly related to the mother's health including increasing rates of obesity, type 2 diabetes, and physical inactivity.
Twin-to-twin transfusion syndrome (TTTS), also known as feto-fetal transfusion syndrome (FFTS), twin oligohydramnios-polyhydramnios sequence (TOPS) and stuck twin syndrome, is a complication of monochorionic multiple pregnancies (the most common form of identical twin pregnancy) in which there is disproportionate blood supply between the fetuses.
a problem with the fetus; a problem with the placenta; a tumor or liver disease in the woman; a normally elevated AFP in the fetus or woman (some people naturally have very high AFP) 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 ...
Low amniotic fluid can be attributed to a maternal, fetal, placental or idiopathic cause and can result in poor fetal outcomes including death. The prognosis of the fetus is dependent on the etiology, gestational age at diagnosis, and the severity of the oligohydramnios.
The condition was previously known as "Amnionknötchen" (amniotic nodules) and was first described in 1850. [2] Amnion nodosum is a placental hallmark of severe and prolonged oligohydramnios, and it is associated with a high risk of fetal and perinatal mortality. The cause and pathophysiology of nodule formation in Amnion nodosum are largely ...
