    3. Abdominal Pain in Pregnancy
  2. Definitions
    1. Ectopic Pregnancy
      1. Implantation of fertilized ovum outside of the Uterus
    2. Pregnancy of Unknown Location
      1. Positive Pregnancy Test but no intrauterine pregnancy or ectopic visible on Transvaginal Ultrasound
  3. Epidemiology
    1. Incidence: 1-2% of all pregnancies
    2. Second most common cause of maternal mortality
      1. Accounts for 2.7% of maternal deaths (as high as 10-15% of maternal deaths in past)
      2. Case fatality rate: 3.8 deaths per 10,000 ectopics
  4. Risk Factors
    1. Highest risk factors
      1. Prior tubal surgery (Odds Ratio 21.0)
      2. Sterilization such as Tubal Ligation (Odds Ratio 9.3)
      3. Prior Ectopic Pregnancy (Odds Ratio 8.3, represents 11% of cases)
        1. History of 1 Ectopic Pregnancy: 10% risk of subsequent Ectopic Pregnancy
        2. History of 2 ectopic pregnancies: 25% risk of subsequent Ectopic Pregnancy
      4. Intrauterine Device (IUD) (Odds Ratio 5.0, represents 14% of cases)
        1. Pregnancy risk itself is <1% with IUD in place
        2. However, when a pregnancy does occur with an IUD, >50% of cases are ectopic
        3. Different IUD types (Copper-T, Mirena) have similar Ectopic Pregnancy rates
      5. In-vitro fertilization
      6. Diethylstilbestrol Exposure (DES Exposure) in utero (Odds Ratio 5.6)
    2. Moderate risk factors
      1. Pelvic Inflammatory Disease or other tubal infection (Odds Ratio 3.4)
      2. Prior fallopian tube surgery
      3. Infertility for 2 years or longer (Odds Ratio 2.7, represents 15% of cases)
      4. Multiple sexual partners
      5. Advanced maternal age >35-40 years old (Odds Ratio 2.9)
      6. Tobacco Abuse (via impaired tubal motility, Odds Ratio 3.9 for 1 ppd, 3.1 for 0.5 ppd)
    3. Other risk factors
      1. Endometriosis
      2. Mini Pill use (Progestin Only Pill)
      3. Vaginal Douching
      4. Early age at first intercourse (age <18 years)
  5. Symptoms

    2. Onset of symptoms occurs on average ~7 weeks after Last Menstrual Period
    3. Abdominal Pain (>97% of cases)
      1. May be non-specific, sharp or crampy, diffuse or localized
      2. Typically starts with colicky unilateral Abdominal Pain or Pelvic Pain (as fallopian tube dilates)
      3. Pain generalizes with peritoneal signs with fallopian tube rupture and Hemorrhage
    4. Vaginal Bleeding (75% of cases)
      1. Results from sloughing of Decidual endometrium
      2. Decidual cast may falsely appear as products of conception (ectopic misdiagnosed as Miscarriage)
      3. Varies from spotting to heavy bleeding with clots

      5. Diverticulitis
      6. Mesenteric Lymphadenitis
  8. Labs
    1. See Imaging below
    2. Quantitative hCG
      1. HCG increases in a predictable pattern in normal pregnancies
        1. bHCG may be detectable as early as 8 days after Ovulation
        2. bHCG <1500: Increases 49-53% (and typically doubles) every 48 hours in 99% of normal pregnancies
        3. bHCG 1500 to 3000: Increases 40% every 48 hours in normal pregnancies
        4. bHCG >3000: Increases 33% every 48 hours in normal pregnancies
        5. Levels off after bHCG reaches 100,000 at approximately 8-10 weeks gestation
        6. Barhart (2016) Obstet Gynecol 128(3): 504-11 [PubMed]
      2. bHCG with inadequate increase may suggest Ectopic Pregnancy
        1. Test Sensitivity: 36% (some studies report 71%)
        2. Test Specificity: 65%
        3. bHCG also increases inadequately (<50%) in 1% of viable pregnancies
        4. bHCG decreases by <35% in up to 7% of 10% of Spontaneous Abortions
      3. bHCG should not be used to defer Ultrasound when Ectopic Pregnancy is considered
        1. Intrauterine pregnancy is first confirmed on Transvaginal Ultrasound at bHCG 1500-2000 IU/L
          1. In some cases intrauterine pregnancy may not be visible until bHCG >3500 IU/L
        2. However, 40% of ectopic pregnancies are identified at bHCG less than 1000 mIU/ml
        3. Ectopic pregnancies have occurred with bHCG as low as 10 mIU/ml
      4. bHCG level does not predict ruptured ectopic
        1. Ruptured ectopic may occur at any bHCG level
      5. bHCG must be followed serially with all management protocols
        1. Follow bHCG to non-detectable levels (may need as long as 6 weeks)
        2. If bHCG start to rise again after falling, repeat Ultrasound is needed
    3. Blood Type and Rh, hold units
      1. Rh Negative women should be administered 300 mcg (or 50 mcg) RhoGAM if bleeding
    4. Complete Blood Count
      1. Leukocytosis
    5. Urinalysis with microscopic exam
    6. Culdocentesis
      1. Rarely performed now due to Transvaginal Ultrasound
      2. Differentiates ruptured Ovarian Cyst from ectopic
      3. Yield of aspirate with >15% Hematocrit suggests bleed
    7. Tests not recommended for ectopic diagnosis
      1. Serum Progesterone (Test Sensitivity: 15%)
  9. Imaging
    1. Precautions
      1. Transvaginal Ultrasound should be performed regardless of bHCG level when Ectopic Pregnancy is considered
      2. In 40% of Ultrasound diagnosed Ectopic Pregnancy cases, bHCG was below 1000 mIU/ml
      3. Counselman (1998) J Emerg Med 16(5): 699-703 [PubMed]
    2. General
      1. Findings suggestive of intrauterine pregnancy
        1. Intrauterine Gestational Sac suggests intrauterine pregnancy
          1. Central blastocyst
          2. Surrounding double ring of echogenic Decidua and chorionic villi (double Decidua sign, 4.5-5 weeks)
          3. Yolk Sac confirms intrauterine pregnancy wiith PPV 100% (5-6 weeks)
        2. Exceptions

            2. Fertility patient Incidence: 1 in 300 (may be 1 in 30 for some types of fertility treatment)
            3. Ultrasound misses Heterotopic Pregnancy in 50% of cases at 5-6 weeks
      2. Findings suggestive of Ectopic Pregnancy
        1. Absence of Gestational Sac at bHCG 1500-1800

        1. Confirms intrauterine pregnancy (100% Positive Predictive Value)
      5. Fetal Pole (Day 40, Gestational Sac>18 mm, bHCG 5000)
      6. Fetal Heart Activity (Day 45 or 6-7 weeks, crown rump length >5 mm, bHCG 17,000)

Ectopic Pregnancy (C0032987)

Definition (MEDLINEPLUS)

The uterus, or womb, is an important female reproductive organ. It is the place where a baby grows when a woman is pregnant. If you have an ectopic pregnancy, the fertilized egg grows in an abnormal place, outside the uterus, usually in the fallopian tubes. The result is usually a miscarriage.

Ectopic pregnancy can be a medical emergency if it ruptures. Signs of ectopic pregnancy include

  • Abdominal pain
  • Shoulder pain
  • Vaginal bleeding
  • Feeling dizzy or faint

Get medical care right away if you have these signs. Doctors use drugs or surgery to remove the ectopic tissue so it doesn't damage your organs. Many women who have had ectopic pregnancies go on to have healthy pregnancies later.

Dept. of Health and Human Services Office on Women's Health

Definition (NCI) An abnormal pregnancy in which the conception is implanted outside the endometrial cavity.
Definition (NCI_NCI-GLOSS) A condition in which a fertilized egg grows outside of the uterus, usually in one of the fallopian tubes. Symptoms include sharp pain on one side of the abdomen and bleeding from the vagina.
Definition (NCI_FDA) The state or condition of having a developing embryo or fetus in the body (outside the uterus), after union of an ovum and spermatozoon, during the period from conception to birth.
Definition (MSH) A potentially life-threatening condition in which EMBRYO IMPLANTATION occurs outside the cavity of the UTERUS. Most ectopic pregnancies (>96%) occur in the FALLOPIAN TUBES, known as TUBAL PREGNANCY. They can be in other locations, such as UTERINE CERVIX; OVARY; and abdominal cavity (PREGNANCY, ABDOMINAL).
Definition (CSP) development of a fertilized ovum outside of the uterine cavity.
