Methods of AFV assessment are reviewed separately. An AFV value of 8 centimeters or more suggests polyhydramnios.An alternative way of measuring amniotic fluid is measuring the largest pocket in four specific parts of your uterus. He or she will estimate the amniotic fluid volume (AFV) by measuring the single largest, deepest pocket of fluid around your baby. Typical symptoms of polyhydramnios include maternal dyspnea, preterm labor, … Work with your pregnancy care provider to ensure that you and your baby receive the best possible care.You're likely to start by talking with your pregnancy care provider. This test uses high-frequency sound waves to produce images of your baby on a monitor.If the initial ultrasound shows evidence of polyhydramnios, your health care provider may do a more detailed ultrasound. Ultrasound diagnosis: The vertical measurement of the deepest pocket of amniotic fluid free of fetal parts is used to classify polyhydramnios into mild (8–11 cm), moderate (12–15 cm) and severe (≥16 cm). Even cases that cause discomfort can usually be managed without intervention.In other cases, treatment for an underlying condition — such as diabetes — may help resolve polyhydramnios.If you experience preterm labor, shortness of breath or abdominal pain, you may need treatment — potentially in the hospital. The sum of these measurements is the amniotic fluid index (AFI). Your health care provider will also use a detailed ultrasound to diagnose or rule out birth defects and other complications. The potential causes of polyhydramnios are variable including: 1. idiopathic: 60-65%: this is a diagnosis of exclusion despite accounting for a majority of cases, also termed idiopathi… It is typically diagnosed when the amniotic fluid index (AFI) is greater than 24 cm. Polyhydramnios is a medical condition describing an excess of amniotic fluid in the amniotic sac.It is seen in about 1% of pregnancies. In about 80% of cases the polyhydramnios is mild, in 15% moderate and in 5% severe. Monitoring may include the following:Mild cases of polyhydramnios rarely require treatment and may go away on their own. Objective: To investigate the short- and long-term outcomes of children from pregnancies complicated with polyhydramnios, defined as amniotic fluid index (AFI) >24 cm, and with a normal detailed ultrasound examination. It can occur in approximately 1-1.5% of pregnancies.Polyhydramnios occurs as a result of either increased production or decreased removal of amniotic fluid. When this happens, the uterus becomes larger than normal.

The diagnosis is made prenatally based upon ultrasound examination showing excessive amniotic fluid volume (AFV) by a noninvasive quantitative technique, such as amniotic fluid index ≥24 cm or single deepest pocket ≥8 cm.
Additional tests may include:If you're diagnosed with polyhydramnios, your health care provider will closely monitor your pregnancy.

In this condition, too much amniotic fluid (the liquid that surrounds the baby in the womb) collects in the uterus. The prognosis of polyhydramnios depends on its cause and severity. Testing will be based on your risk factors, exposure to infections and prior evaluations of your baby. The potential causes of polyhydramnios are variable including:Polyhydramnios is associated with the poor outcome if present in combination with This classification is general consensus based on common practices at the time of writing (July 2016) but this varies according to countries and gynecologist association guidelines.The risk of the following obstetric complications is increased when polyhydramnios is present due to over-expansion of the uterusThe prognosis is variable dependent on associated conditions.
