The use of oligohydramnios as a predictor of gestational complications is controversial. [23] [24] Potter syndrome is a condition caused by oligohydramnios. Affected fetuses develop pulmonary hypoplasia, limb deformities, and characteristic facies. Bilateral agenesis of the fetal kidneys is the most common cause due to the lack of fetal urine.
Oligohydramnios is the cause of Potter sequence, but there are many things that can lead to oligohydramnios. It can be caused by renal diseases such as bilateral renal agenesis (BRA), atresia of the ureter or urethra causing obstruction of the urinary tract, polycystic or multicystic kidney diseases, renal hypoplasia , amniotic rupture ...
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 unknown.
Features of post-maturity syndrome include oligohydramnios (a deficiency of amniotic fluid); [4] meconium aspiration (breathing meconium in the amniotic fluid); and macrosomia (being overly large). The syndrome also causes fetal problems like dry peeling skin, overgrown nails, abundant scalp hair, visible creases on palms and soles, absence of ...
External physical shocks or constraints due to growth in a restricted space may result in unintended deformation or separation of cellular structures resulting in an abnormal final shape or damaged structures unable to function as expected. An example is Potter syndrome due to oligohydramnios. This finding is important for future understanding ...
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.
Causes of pulmonary hypoplasia include a wide variety of congenital malformations and other conditions in which pulmonary hypoplasia is a complication. [1] These include congenital diaphragmatic hernia, congenital cystic adenomatoid malformation, fetal hydronephrosis, caudal regression syndrome, mediastinal tumor, and sacrococcygeal teratoma with a large component inside the fetus.
This absence of kidneys causes oligohydramnios, a deficiency of amniotic fluid in a pregnancy, which can place extra pressure on the developing baby and cause further malformations. The condition is frequently, but not always the result of a genetic disorder , and is more common in infants born to one or more parents with a malformed or absent ...
