Diagnosis of oligohydramnios is based on ultrasound when the measurement along the deepest amniotic cavity (where only amniotic fluid is present, no fetal body parts) is less than 2cm or the amniotic index AFI (total of 4 amniotic sacs) is less than 5 cm.
There are 4 main causes of oligohydramnios :
Amniotic fluid rupture , amniotic fluid leakage before labor : Because the amniotic membrane is torn causing amniotic fluid to escape from there leading to oligohydramnios .
