Gestation Flashcards
Most common place for ectopic pregnancies
lumen of tube
Biggest risk for ectopic pregnancy
scarring of tube
PID
endometriosis
Spontaneous abortions are usually caused by
chromosomal abnormalities in fetus
When no chromosomal abnormalities, spontaneous abortions are normally caused by
hypercoagulable states ie SLE
Placenta previa
preview of placenta, sitting over cervial os
compression of fetal blood supply during delivery
C-section that baby out
Placental abruption
etiology
complications
caused by separation of placenta from decidua
common cause of stillbith–fetal compromise
Placenta accreta
placenta bound up into myometrium
requires surgical removal of placenta
or she is going to bleed like crazy
Preeclampsia definition
hypertension and proteinuria due to placental vessle compromise
Preeclampsia
pathological finding in placenta
fibrinoid necrosis of placental vessels
HELLP syndrome
complication of pre-eclampsia hemolysis elevated liver enzymes low platelets (microthrombi in liver --> liver tissue damage and using up of platelets --> thrombocytopenia and microangiopathic hemolysis)
Risk factors for SIDS
cigarette exposure
sleeping on stomach
prematurity
Complete mole formation
2 sperm fertilize an empty ovum
- absent fetal tissue
- edematous/hydropic villi
- lots of trophoblasts
- 2-3% risk of choriocarcinoma
Partial mole formation
normal ovum fertilized by 2 sperm or 1 sperm that duplicates
- fetal tissue present
- some edematous/hydropic villi
- focal trophoblast formation
- low risk of choriocarcinoma
Tests that makes you think it might be a molar pregnancy
very, very high hCG
because molars are basically just a ton of trophoblasts
trophoblasts form hCG
No prenatal care
molar pregnancy presentation
passing grape-like masses of tissue
