amniotic band syndrome (ABS)

multiple fibrous strands of amnion that develop in utero and may entangle fetal parts to cause amputations or malformations of the fetus


amniotic cavity

forms early in gestation and surrounds the embryo; amniotic fluid fills the cavity to protect the embryo and fetus


amniotic fluid

produced by the umbilical cord and membranes, the fetal lung, skin, and kidney


amniotic fluid index (AFI)

the uterus is divided into four quadrants, each of which is evaluated with the transducer perpendicular to the table in the deepest vertical pocket without fetal parts; the amniotic fluid index equals the four quadrants added together



generalized swelling and edema of skin throughout the body



abnormal serous fluid collection found in the abdomen or pelvis


Asherman’s syndrome

acquired uterine condition characterized by the presence of intrauterine scars or synechiae



bacterial infection of the fetal membranes usually due to the upward ascent of a vaginal infection


corticosteroid therapy

administered to pregnant women to help accelerate fetal lung maturity



increased amount of amniotic fluid


hydrops fetalis

abnormal accumulation of fluid or edema found in at least two fetal areas


immune hydrops fetalis (IHF)

accumulation of abnormal fluid collections caused by rhesus incompatibility


maximum vertical pocket

method used to determine the amount of amniotic fluid; a pocket less than 2 cm may indicate oligohydramnios; greater than 8 cm indicates polyhydramnios


nonimmune hydrops fetalis (NIHF)

accumulation of abnormal fluid collections not caused by rhesus incompatibility



too little amniotic fluid; associated with intrauterine growth restriction, renal anomalies, premature rupture of membranes, postdate pregnancy, and other factors


pericardial effusion

abnormal collection of fluid surrounding the heart greater than 2 mm


placental insufficiency

inability of placenta to provide adequate blood/nutrient supply to the fetus because of underlying maternal disease, such as hypertension or diabetes, or because of extensive placental abruption


pleural effusion

abnormal fluid collection in the thoracic cavity



too much amniotic fluid; associated with central nervous system disorder, gastrointestinal anomalies, fetal hydrops, skeletal anomalies, renal disorders, and other factors


premature rupture of membranes (PROM)

condition in which the amniotic bag has ruptured, labor has not begun, and the pregnancy is beyond 37 weeks’ gestation


preterm premature rupture of membranes (PPROM)

condition in which the amniotic bag has ruptured, labor has not yet begun, and the pregnancy is at less than 37 weeks’ gestation


spontaneous premature rupture of membranes (SPROM)

condition in which the amniotic bag ruptures with labor or just after labor begins


subjective assessment

sonographer surveys uterine cavity to visually assess amniotic fluid present



scars within the uterus secondary to previous gynecologic surgery


vernix caseosa

fatty material found on fetal skin and in amniotic fluid late in pregnancy
