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.
Amniotic fluid index (AFI) is a quantitative estimate of amniotic fluid [1] and an indicator of fetal well-being. It is a separate measurement from the biophysical profile. [1]
Amniotic fluid levels are an important consideration when debating expectant management vs clinical intervention, as low levels, or oligohydramnios, can result in lung and limb abnormalities. [10] Additionally, labor and infection are less likely to occur when there are sufficient levels of amniotic fluid remaining in the uterus. [ 8 ]
Bacterial, viral, and even fungal infections can cause chorioamnionitis. Most commonly from Ureaplasma, Fusobacterium, and Streptococcus bacteria species. Less commonly, Gardnerella, Mycoplasma, and Bacteroides bacteria species.
