Flashcards in Gestation Deck (18):
1

Most common place for ectopic pregnancies

lumen of tube

2

Biggest risk for ectopic pregnancy

scarring of tube
PID
endometriosis

3

Spontaneous abortions are usually caused by

chromosomal abnormalities in fetus

4

When no chromosomal abnormalities, spontaneous abortions are normally caused by

hypercoagulable states ie SLE

5

Placenta previa

compression of fetal blood supply during delivery
C-section that baby out

6

Placental abruption
etiology
complications

caused by separation of placenta from decidua
common cause of stillbith--fetal compromise

7

Placenta accreta

placenta bound up into myometrium
requires surgical removal of placenta
or she is going to bleed like crazy

8

Preeclampsia definition

hypertension and proteinuria due to placental vessle compromise

9

Preeclampsia
pathological finding in placenta

fibrinoid necrosis of placental vessels

10

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)

11

Risk factors for SIDS

cigarette exposure
sleeping on stomach
prematurity

12

Complete mole formation

2 sperm fertilize an empty ovum
-absent fetal tissue
-edematous/hydropic villi
-lots of trophoblasts
-2-3% risk of choriocarcinoma

13

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

14

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

15

No prenatal care
molar pregnancy presentation

passing grape-like masses of tissue

16

What molar pregnancy looks like when you catch it on ultrasound

snowstorm look of uterus

17

Feared complication in molar pregnancies

development of choriocarcinoma

18

Two pathways of choriocarcinoma

germ cell tumor: poor response to chemo
gestation-related: good response to chemo
