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 ...
Duodenal atresia is the congenital absence or complete closure of a portion of the lumen of the duodenum.It causes increased levels of amniotic fluid during pregnancy (polyhydramnios) and intestinal obstruction in newborn babies.

Physicians have used the process of inserting a needle transabdominally into the uterus to extract excess amniotic fluid, also known as a reductive amniocentesis or decompression, for the management of polyhydramnios as early as the late 1800s. [6] [7] Reductive amniocentesis is currently indicated for severe cases of polyhydramnios only. [22]
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.
Tubes filled with amniotic fluid for amniocentesis. The amniotic fluid is the protective liquid contained by the amniotic sac of a gravid amniote.This fluid serves as a cushion for the growing fetus, but also serves to facilitate the exchange of nutrients, water, and biochemical products between mother and fetus.
The fetal symptoms are related to fluid retention, including ascites and polyhydramnios. [3] Fetal hydrops suggests the presence of an important and probably fatal fetal pathology . It can be associated with parvovirus B19 infection and with twin-to-twin transfusion syndrome .
Since its initial characterization, Potter sequence has been defined into five distinct subclassifications. There are those in the medical and research fields that use the term Potter sequence to specifically refer to only cases of BRA, while other groups use the term to loosely refer to all instances of oligohydramnios and anhydramnios regardless of the specific cause.
