Background
- Must consider in all women of childbearing age who p/w abd/pelvic pain + hypovolemia
- Leading cause of maternal death in first trimester
- Pregnancy in patient with prior tubal ligation or IUD in place is ectopic until proven otherwise (25-50% are ectopic)
Risk Factors
- Major
- H/O PID
- History of tubal surgery or IUD in place
- Previous ectopic
- Minor
- Tobacco
- Assisted reproduction techniques
- Age >35
- Numerous lifetime partners
Diagnosis
Clinical Features
- Abdominal/pelvic pain
- Vaginal bleeding
- Amenorrhea
HCG Level
- Helpful in characterizing risk of ectopic, but can NOT be used to rule-out ectopic
- Normal pregnancy: hCG should double every 2d until 10000 mIU/ml
- Ectopic pregnancy: hCG increases more slowly or decreases (esp w/ spont. abortion)
Ultrasound: Pelvic
- Used to identify presence or absence of IUP
- IUP in setting of fertility tx does not necessarily r/o ectopic (heterotopic pregnancy)
- Discriminant zone
- There is no discriminant zone for an ectopic pregnancy:
- Perform US if ectopic is suspected regardless of the hCG level
- Transvag US for IUP: 1500 mIU/ml
- If hCG > 1500 and no IUP - assume EP
- Transabd US for IUP: 6000 mIU/ml
- There is no discriminant zone for an ectopic pregnancy:
- Findings
- Gestational sac alone does NOT equal IUP (must also have yolk sac)
DDX
