termination of pregnancy by the expulsion from the uterus of an embryo or fetus before viability, usually before 20 weeks of gestation. Spontaneous abortion is the termination of pregnancy that occurs naturally and is commonly referred to as miscarriage. Induced abortion is the intentional termination of pregnancy by surgical or medical intervention.
81

premature separation of the placenta from the uterine wall; can cause antepartum hemorrhage (severe bleeding before giving birth); (also called placental abruption)

Serious condition that increases the risk of postpartum hemorrhage (severe bleeding after giving birth).
85
placenta previa
abnormally low implantation of the placenta on the uterine wall completely or partially covering the cervix. Dilation of the cervix can cause separation of the placenta from the uterine wall, resulting in bleeding. With severe hemorrhage, a cesarean section is necessary to save the mother and baby’s life.
86

congenital fissure of the abdominal wall that is not at the umbilicus. Enterocele, protrusion of the intestine, is usually present.
102
respiratory distress syndrome (RDS)
respiratory complication in the newborn, especially in premature infants. In premature infants RDS is caused by normal immaturity of the respiratory system, resulting in compromised respiration. (formerly called hyaline membrane disease)
103
spina bifida

104
amniotomy
incision into the amnion (rupture of the amniotic sac to induce labor; a special hook is generally used to make the incision)

birth of a fetus through an incision in the mother’s abdomen and uterus (may also be spelled caesarean)
108
in vitro fertilization (IVF)
method of fertilizing human ova outside the body and placing the zygote into the uterus; used when infertility is present
109
amniocentesis
surgical puncture to aspirate amniotic fluid (The needle is inserted through the abdominal and uterine walls, using ultrasound to guide the needle. It is a prenatal test in which the fluid is used for the assessment of fetal health and maturity to aid in diagnosing fetal abnormalities.)
110
pelvic sonography
pertaining to the pelvis, process of recording sound; used extensively to evaluate the fetus and pregnancy (also called pelvic ultrasonography, pelvic ultrasound, and obstetric ultrasonography)
111
nuchal translucency screening
ultrasound test to check the back of the fetal neck for extra fluid or thickening. It is usually performed between 11 and 13 weeks of pregnancy and, when combined with first trimester screening blood tests, may reveal an increased risk for Down syndrome or other congenital disorders.
112
quad screen
blood test performed during the second trimester measuring four hormone levels that can reveal an increased risk of certain disorders in the developing fetus.
113
