Ectopic Flashcards
Types of Ectopic Pregnancy
Tubal
Ovarian
Abdominal
Cervical
Heterotopic
Tubo-uterine
Tubo-abdominal
Most common site (95%) of implantation of ectopic pregnancy
Tubal
Pregnancy occurs when a fertilized egg implants on the surface of the
ovary.
Ovarian
Extremely rare type (1/15,000);
Abdominal
Present with vaginal bleeding, which can be profuse and is often
painless.
Cervical
Existence of two simultaneous pregnancies with separate implantation
sites.
Heterotopic
Results from the gradual extension into the uterine cavity of products of
conception that originally implanted in the interstitial portion
Tubo-uterine
A zygote that is originally implanted at the end of the fallopian tube
gradually extends into the peritoneal cavity.
Tubo-abdominal
A zygote that is partly implanted in the tube & partly in the ovary
Tubo-ovarian
Diagnosis & Tests for ectopic
TVUS
Serial HCG
Determination
Pregnancy Test
Serum
Progesterone
Levels
Colpotomy
Culdocentesis
CBC
Reveals extrauterine pregnancy
TVUS
Direct visualization of the oviducts & ovaries.
Colpotomy
Extraction of fluid from the rectouterine pouch posterior to the
vagina through a needle.
Diagnose the presence of ruptured ectopic pregnancy
Culdocentesis
For unruptured EP what is performed
therapeutic abortion
Methotrexate (chemotherapy agent; immune suppressant)
Methotrexate has been associated with
stomatitis,
gastritis, hepatic enzyme elevation, pneumonitis, &
hematologic toxicity
given on alternate days to decrease the hematologic toxicity of Methotrexate.
IM leucovorin (like folic acid)
Management of Ectopic Pregnancy
For ruptured EP
Salpingectomy
Hysterectomy
Oophorectomy
Management for uncontrollable hemorrhage & severely damaged tube ; removal of one or both fallopian tubes
Salpingectomy
Management for often for ruptured interstitial or cervical
pregnancy
Hysterectomy
A benign disorder of the placenta characterized by
degeneration of the chorion & death of the embryo.
Hydatidiform Mole
Types of Molar Pregnancy
Complete Molar
Partial Molar
Embryo can’t grow
Sperm fertilizes an empty egg
The tissue produces HCG, which gives a (+) pregnancy
test.
Complete Molar
An extra set of chromosomes
comes from the father (two
sperm fertilized one egg).
Mother’s 23 chromosomes
remain intact.
The embryo has 69 instead of
the normal 46 chromosomes.
Growing embryos start to
develop but can’t SURVIVE!
Partial Molar
Diagnosis and Tests for hmole
USS of the uterus
HCG levels in the blood
shows fluid-filled sacs instead of the placenta
