oligohydramnios
Pronunciation: OH-li-goh-hi-DRAM-nee-ohs
Decreased amniotic fluid volume that may complicate fetal surgical procedures and recovery.
Full Definition
Oligohydramnios refers to an abnormally low volume of amniotic fluid surrounding the fetus, typically defined as an amniotic fluid index less than 5 cm or deepest vertical pocket less than 2 cm. In the context of fetal surgery, oligohydramnios can develop as a complication of uterine manipulation or membrane rupture, potentially leading to cord compression, impaired fetal lung development, and increased surgical complexity.
