Ectopic Pregnancy: Causes and Risk Factors
- Anything that blocks or slows the movement of the egg through the fallopian tubes
- Birth defect in the fallopian tubes
- Scarring after a ruptured appendix
- Having an ectopic pregnancy before
- Scarring from past infections or surgery of the female organ
Ectopic Pregnancy: Increased Risk Factors

- Infertility treatment
Ectopic Pregnancy: Symptoms
- breast tenderness
- nausea
- Abnormal vaginal bleeding
- Low back pain
- Mild cramping on one side of the pelvis
- No periods
- Pain in the lower belly or pelvic area (sharp and stabbing)
Ectopic Pregnancy: If the area around the abnormal pregnancy ruptures and bleeds:
- Fainting or feeling faint
- Intense pressure in the rectum
- Low blood pressure
- Pain in the shoulder area
- Severe, sharp, and sudden pain in the lower abdomen
Ectopic Pregnancy: Diagnostic Exams
- Pelvic Exam

- Treatment for shock may include:
-Blood transfusion- Fluids given through a vein
- Keeping warm
- Oxygen
- Raising the legs
- Surgery
- stop blood loss
- remove the pregnancy
- removal of the fallopian tube (some cases)
- If the ectopic pregnancy has not ruptured:
- Surgery
- Medicine that ends the pregnancy
Ectopic Pregnancy: Prevention
Not really preventable but may reduce risks:
- Practicing safer sex by taking steps
before and during sex
- Getting early diagnosis and treatment of all infections caused by sexual relations (STDs)
- Stop smoking
Loss of pregnancy before 20 weeks of gestation without outside intervention
First trimester bleeding
Viable fetus
- more than 20-24 weeks
- Or weighs at least 500 g
Spontaneous Abortion
Types of Abortion
- Threatened abortion
- Inevitable abortion
- Complete abortion
- Incomplete
- Missed abortion
- Recurrent abortion
Mnemonic: TICIM R
- -bright red and scant vaginal bleeding
- there is the presence of a viable pregnancy with a closed cervix
- Early under 16 weeks
- Late 16-24 weeks
- Avoid sexual intercourse 2 weeks after
Threatened Abortion
- Imminent
- Cervix has dilated
- Membranes have ruptured
- The products of conception remain in utero
- There is uterine contractions
- Bleeding within 2 hours and ceases within 2 days
Inevitable Abortion
- Refers to the spontaneous passage of all the products (fetus, membrane, placenta) of conception
- does not require medical treatment
Complete Abortion
Part expelled usually the fetus and membranes and placenta retained
Incomplete Abortion
- Early pregnancy failure
- Characterized by intrauterine fetal death (IUFD) and retention of the products of conception
- Fetus died 4-6 weeks before symptoms
Missed Abortion
- Habitual aborters
- A history of 3 or more spontaneous pregnancy losses at the same gestational age
Recurrent Abortion
Recurrent Abortion: Causes
- Defective ova or spermatozoa
- Endocrine factors
- Decrease Protein-bound iodine (PBI)
- Decrease globulin iodine (GBI)
- Poor thyroid function
- just Luteal phase defect
- Deviations of the uterus
- Septate
- Bicornuate uterus
- Resistance to uterine artery blood flow
- Chorioamnionitis (uterine infections)
- Auto immune disorders
- Lupus anticoagulants

INTRAUTERINE CAUSES
a. Ashermansyndrome
b. Fibroids
c. Uterine malformations
- occurs following curettage of the uterus
- Severe degrees of intrauterine adhesions
- leads to obstruction of the uterine cavity and subsequent infertility
Asherman Syndrome
Asherman syndrome: Mild degrees of adhesions are associated with:
- pregnancy loss
- insufficient amount of normal endometrial tissue
for implantation and placental development - defective vascularization of the remaining endometrial tissue caused by fibrosis
- Women with submucosal fibroids (1.8% risk of miscarriage)
- involves a projection of the submucosal fibroids into the uterine cavity
- distortion of the blood supply in the endometrium
- interferes with embryonic implantation
Fibroids
Is the most common malformation of the uterus
