定义
胎盘功能不全是指胎盘无法向胎儿提供足够的氧气和营养物质，因此不能维持发育中的婴儿成长到足月。胎盘功能不足可能导致胎儿宫内生长受限（IUGR）、先兆子痫、胎盘早剥、或早产和分娩。小胎盘是指胎盘重量低于妊娠期的正常下限。胎盘重量低可能是由于母体或胎儿情况所致，母体情况导致胎盘灌注不足，如先兆子痫或母体高血压。胎儿情况适于胎儿畸形或染色体异常。
Placental insufficiency is defined as the inability of the placenta to deliver a sufficient supply of oxygen and nutrients to the fetus, and therefore, is unable to sustain the growth of the developing baby until term. Placental insufficiency can result in intrauterine growth restriction (IUGR), pre-eclampsia, abruption, or preterm labour and delivery. A small placenta is defined as a placenta that weighs less than the lower limit of normal for the gestational period. A low placental weight can be the result of a maternal or fetal conditions. Among maternal conditions belong those causing underperfusion of the placenta, such as pre-eclampsia or maternal hypertension. Among fetal conditions belong fetal malformations or chromosomal anomalies.
