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 ...
Twin oligohydramnios-polyhydramnios sequence is a rare condition that may occur when twins sharing a single placenta develop significant vascular cross-connections, known as anastomoses, resulting in blood flowing away from one twin to the other. [23] This process can result in polyhydramnios in one twin and oligohydramnios in the other twin. [23]

The Apgar score is a quick way for health professionals to evaluate the health of all newborns at 1 and 5 minutes after birth and in response to resuscitation. [1] It was originally developed in 1952 by an anesthesiologist at Columbia University, Virginia Apgar , to address the need for a standardized way to evaluate infants shortly after birth.
The newborn, with normal APGAR scores and umbilical cord arterial pH levels, was admitted to the neonatal intensive care unit. Upon examining the placenta after delivery, it was noted that the placenta demonstrated the appearance of a circumvallate placenta, and also showed evidence of abnormal umbilical cord insertion into the placenta.
polyhydramnios, or an abnormally high amount of amniotic fluid [8] prematurity: likely related to increased chance of malpresentation and relative polyhydramnios. [8] low birth weight: [9] usually described as <2500g at birth, though some studies will use <1500g. Cause is likely similar to those for prematurity.
Women with abnormal amounts of amniotic fluid, whether too much (polyhydramnios) or too little (oligohydramnios), are also at risk. [35] Anxiety and depression have been linked as risk factors for preterm birth. [35] [61] The use of tobacco, cocaine, and excessive alcohol during pregnancy increases the chance of preterm delivery.
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.
