Mother and child (ERF) Flashcards
this side of the placenta is deep maroon
maternal surface
this side of placenta is gray, glistening, and translucent
Fetal surface
A benign hemangioma, of no consequence unless it is huge, in which case it acts as a shunt, consumes the baby’s platelets, and cause congestive heart failure
Chorangioma
The basal plate (mom’s side) is quite a bit bigger than the chorionic plate (baby’s side); this will appear as a ring around the edge on the fetal surface. this can cause various problems as you’d expect, since the baby’s wrapped up inside
Circumvallate placenta
-note circummarginate placenta is a forme fruste thats not so worrisome
Granulomatized sloughed baby skin cells. See bumps. Usually we see oligohydramnios.
amnion nodosum
Is a cord attached to the membrane but away from the placentas. Places the child at greater risk
Velamentous insertion
Common cause of miscarriage and can result in damage to body parts in a baby that makes it to term
Amniotic band syndrome
Features a good placenta and membranes but no baby
Blighted ovum
-note looks very like a partial mole (according to ERF)
Pathologist will eventually see the villi; unlike hydatidiform mole, there’s atrophy rather than proliferation of trophoblast, and the edema of the villi isn’t impressive
Blighted ovum
Child and placenta are enormous. usually due to congestive heart failure, most often from severe anemia
Hydrops
-note anemia is from parvo 19 (according to ERF)
A twin who died and whose body was flattened by the other childs is called what
Fetus papyraceous
what should we suspect in miscarriage and early birth. Its a bacteria
gardnella
Past infections become a risk for what abnormality
ectopic pregnancy
baby calcifies (Stone child)
lithopedion
common bacteria can infect the placenta. If you see granulomas think what
listeria
-note chlamydia infection is likely to produce red eyes in newborn
This occurs when the placenta covers the lower uterine segment over the cervical outlet. this can cause premature labor. As the cervix dilates, BLEEDING OCCURS. LOTS
placenta previa
-risk factor can be an old cesarean scar
Portion of the placenta that lacks decidua, adhering instead directly to the myometrium
Placenta accreta
-risk factor can be an old ceseraen scar
what causes twin-twin transfusion.
one-way valve in the placenta
You have twins. One has Acardius, how does it make it to term
the healthy twin provides blood and a beating heart
What is the greatest risk for pre-clampsia
is a previous pregnancy w/ pre-clampsia with the same father
Pregnant women. BP exceeds 140/90 and there’s 300 mg or more of protein in the urine
Pre-clampsia
-in the liver we will see periportal necrosis plus fatty liver
A women with preclampsia, the walls of the uterine arteries fill with (?) and may undergo extensive fibrinoid necrosis
fill with lipid (atherosis)
-women who die bc of preclampsia its usually the liver that hemorrhages
what does HELLP stand for
Hemolysis, Elevated Liver enzymes, and Low Platelets) this is preclampsia
what is the greatest risk in developing choriocarcinoma
person previously had a hydatidiform mole
