DIFFERENTIALS

Abortion Ovarian Cyst Pelvic Inflammatory Disease Subchorionic Hemorrhage Ectopic Pregnancy

CLINICAL IMPRESSION

31 y/o G4P3 (3013) Ovarian Cyst, Right Amenorrhea 5-6 weeks R/o Tubal Pregnancy,

right Previous Caesarian Section IIIx, Ix for

Cephalopelvic Disproportion (1997, 1998, 2005)

ECTOPIC PREGNANCY

ECTOPIC PREGNANCY

Ektopos: (Greek) out of place Implantation of a fertilized ovum outside

the endometrium lining the uterine cavity Implantation in any other site considered

ectopic Located mostly in the oviducts Other reported sites are the cervix, uterine

cornu, ovaries, abdomen broad ligament, spleen, liver, retroperitoneum and diaphragm

RISK FACTORS: CLASSIFICATION

Mechanical Functional Assisted reproduction Failed contraception

MECHANICAL FACTORS Prevent or retard passage of ovum to uterine cavity Tubal kinking and narrowing secondary to:

Prior tubal surgery: highest risk (failed tubal ligation, tubal fertility surgery, partial salpingiectomy)

Peritubal adhesions 2o to post-abortal/puerperal infection, appendicitis, endometriosis

Salpingitis (previous ectopic): narrowing/blind pockets

Myomas/adnexal masses

MECHANICAL FACTORS

Reduced ciliation 2o to infection: PID (Chlamydia trachomatis), Salpingitis

Developmental tubal abnormalities (diverticula, accessory ostia, hypoplasia)

FUNCTIONAL FACTORS

Altered tubal motility 2o to changes in serum levels of estrogen and progesteroneProgestin only contraceptives IUD devices with progesteronePost-ovulatory high dose estrogenOvulation inductionLuteal phase defects

Cigarette smoking: nicotine is known to alter tubal motility, ciliary activity or blastocyst implantation

Increasing age

ASSISTED REPRODUCTION

Increased incidence with gamete intra-fallopian transfer (GIFT) and in-vitro fertilization (IVF) techniques (atypical implantations more common)

FAILED CONTRACEPTION

With any form of contraceptive, the absolute number of ectopic pregnancies is decreased because pregnancy occurs less often

In some contraceptive failures, however, the relative number of ectopic pregnancies is increased.

RISK FACTORS

Multiple sexual partners Prior Caesarian section

EPIDEMIOLOGY

Increasing absolute number and rate of ectopic pregnancy

Non-Caucasians > Caucasians Increased age 2% of all pregnancies 10% of all pregnancy-related deaths Most common cause of maternal

mortality in the 1st trimester

PATHOPHYSIOLOGY

SITES OF ECTOPIC IMPLANTATION: CLASSIFICATION

Tubal (95-96%) Ampullary (70%) Isthmic (12%) Fimbrial (11%) Cornual and interstitial (2-3%)

Abdominal (1%) Cervical (<1%) CS scar (<1%) Ovarian (3%)

NORMAL ANATOMY OF FALLOPIAN TUBE

ECTOPIC PREGNANCY: CLINICAL PRESENTATION

PAIN. Severe sharp/stabbing or tearing lower pelvic and abdominal pain (95%)

ABNORMAL BLEEDING. Amenorrhea with some degree of vaginal spotting or bleeding (60-80%)

Abdominal and pelvic tenderness (75%) on palpation with or without palpable pelvic mass (20%)

Vasomotor disturbance (vertigo/syncope) with signs of hemodynamic compromise (20%)

CLINICAL PRESENTATION

First trimester uterine changes (25%) Cervical motion tenderness Bulging of posterior fornix

CLASSIC CLINICAL TRIAD: Pain, amenorrhea, vaginal bleeding

ECTOPIC PREGNANCY: DIAGNOSIS

Complete history and physical examination Urinary pregnancy tests: positive in 50% to

95%

ECTOPIC PREGNANCY: DIAGNOSIS

Serum B-hCG serial values lower than in normal

pregnancy best correlated with ultrasound in first 6 weeks of normal gestation,

serum HCG rises exponentially: doubling time is noted and is relatively constant

doubling time does not occur in gestation destined to abort or are ectopic

ECTOPIC PREGNANCY: DIAGNOSIS

Serum progesterone (inconclusive 5-25 ng/ml) A single progesterone measurement can

be used to establish with high reliability that there is a normally developing pregnancy: value exceeding 25 ng/mL excludes ectopic pregnancy with 92.5 % sensitivity

Values <5 ng/mL suggest either an intrauterine pregnancy with a dead fetus or an ectopic pregnancy

Has limited clinical utility

ECTOPIC PREGNANCY: DIAGNOSIS

Novel serum markers under investigation: vascular endothelial growth factor (VEGF), cancer antigen 125 (CA125), creatine kinase, fetal fibronectin, and mass spectrometry-based proteomics

DIAGNOSIS: ULTRASONOGRAPHY Abdominal sonography

Identification of tubal pregnancy products is difficultUterine pregnancy usually is not recognized using

abdominal sonography until 5 to 6 menstrual weeks or 28 days after timed ovulation

Vaginal sonographyUterine pregnancy 1 week after missed menses

with B-hCG >1500 mIU/ml Identification of fetal pole within the uterus with

FHT

PATIENT: TRANSVAGINAL USG

Normal sized AV uterus w/ no myometrial lesion Thin nonspecific endometrium (0.60) Normal right ovary Corpus luteum cyst (3.0x2.8x2.6cm), left ovary Inferomedial and adjacent to right ovary is a

complex mass with a 1.0cm gestational sac-like structure within (~5weeks and 5days AOG).

Slightly echogenic free fluid in the cul-de-sac ~5.2x1.8x3.5cm, volume 11cc with amorphous echogenic structure suggestive of blood clot

IMPRESSION: right adnexal mass highly suggestive of an ectopic gestation, probably tubal with small leak or rupture

VAGINAL COLOR AND PULSED DOPPLER ULTRASOUND

Uterine or extrauterine site of vascular color in characteristic placental shape

Ring of fire pattern High-velocity low impedance flow

pattern compatible with placental perfusion

Ectopic pregnancy: “cold” pattern outside uterus

ECTOPIC PREGNANCY: DIAGNOSIS

Culdocentesis Laparoscopy

MULTIMODALITY DIAGNOSIS: 5 COMPONENTS

Ectopic pregnancies are identified with the combined use of clinical findings along with serum analyte testing and transvaginal sonography.

Transvaginal sonography Serum B-hCG level—both the initial level and

the pattern of subsequent rise or decline Serum progesterone level Uterine curettage Laparoscopy, laparotomy

ECTOPIC PREGNANCY: MANAGEMENT

Medical management Expectant management Surgical management

MEDICAL MANAGAMENT

Medical therapy (Methotrexate) for the patient who is asympotomatic, motivated and compliant

The single best prognostic indicator of successful treatment of single dose methotrexate is the initial serum B-hCG level

Methotrexate: rapid absorption of placental tissue

EXPECTANT MANAGEMENT

Tubal ectopic pregnancies only Decreasing serial -hCG levels Diameter of the ectopic mass not >3.5 cm No evidence of intra-abdominal bleeding or

rupture by transvaginal sonography.

According to the American College of Obstetricians and Gynecologists (2008), 88 percent of ectopic pregnancies will resolve if the B-hCG is <200 mIU/mL.

SURGICAL MANAGEMENT

Laparoscopy - shorter operative time, less blood loss, less analgesic requirement, and shorter hospital stay

Laparotomy Salpingectomy – may be used for both

ruptured or unruptured ectopic pregnancies Salpingostomy - used to remove a small

pregnancy that is usually less than 2 cm in length and located in the distal third of the fallopian tube

Salpingotomy – same with salpingostomy but incision is closed with delayed absorbable suture

SURGICAL MANAGEMENT

SOME PRACTICE GUIDELINES*

 Less than half of the patients with ectopic pregnancy present with the classic triad of a history of amenorrhea, abdominal pain, and irregular vaginal bleeding (C).

Definite cervical motion tenderness and peritoneal signs are the most sensitive and specific examination findings for ectopic pregnancy--91% and 95%, respectively (A).

*Ectopic pregnancy: forget the "classic presentation" if you want to catch it sooner: a new algorithm to improve detection. Journal of Family Practice. May 2006. Ramakrishnan, K., and Scheid, D.C.

SOME PRACTICE GUIDELINES

Beta-hCG levels can be used in combination with ultrasound findings to improve the accuracy of the diagnosis of ectopic pregnancy (A).

Women with initial nondiagnostic transvaginal ultrasound should be followed with serial beta-hCGs (B).

SOME PRACTICE GUIDELINES

Despite advanced detection methods, ectopic pregnancy may be missed in 40% to 50% of patients on an initial visit.

Most women with ectopic pregnancy have no risk factors and the classic triad of a history of amenorrhea, abdominal pain, and irregular vaginal bleeding is absent in more than half of cases.

Early diagnosis not only decreases maternal mortality and morbidity; it also helps preserve future reproductive capacity--only one third of women with ectopic pregnancy have subsequent live births. (2)
