Issues in Early Pregnancy ACOG District I Medical Student
Slide 2-

When a woman presents with an early pregnancy… Ask yourself two questions… Where is this pregnancy? Is it viable?
Slide 3-

Where is this pregnancy? In a woman with an early pregnancy you must determine if the pregnancy is intrauterine or an ectopic, because her life could depend on it!
Slide 4-

How to you determine location of the pregnancy? First determine dating by LMP Then perform ultrasound If you can see location of the pregnancy, you are done! If you cannot…it becomes more complicated…
Slide 5-

Early pregnancy with unknown location Check a serum BHCG If it is above the discriminatory zone (DZ)—(this is different at every hospital) an intrauterine pregnancy should be seen Then do an ultrasound to see if you see the pregnancy
Slide 6-

Early pregnancy with unknown location If BHCG>DZ and pregnancy seen in the uterus, you are done If BHCG>DZ and no pregnancy seen in the uterus, it is an ectopic until proven otherwise!
Slide 7-

Ectopic pregnancy 2% of all pregnancies Risk factors include prior tubal surgery, prior ectopic, current IUD use, history of PID, or DES exposure A woman can present with abdominal pain or bleeding or be asymptomatic!
Slide 8-

Ectopic Pregnancy 95% are in the fallopian tube (70% ampulla, 12% isthmus, 11% fimbria, 2% interstitial/cornual) Ovarian occurs about 3% of the time, abdominal 1% of the time and cervical <1% of the time Seeber 2006
Slide 9-

Early pregnancy with unknown location If BHCG< DZ and you do not see the pregnancy on the ultrasound consider your patient… Is she…. Unstable or stable Have pain? Have risk factors for ectopic? Your differential diagnosis is :intrauterine pregnancy just too small to see on ultrasound vs ectopic
Slide 10-

Early pregnancy with unknown location Generally, BHCG will double in 48 hours If the patient is stable you can have her return in 48 hours for repeat BHCG If is doubling appropriately, likely normal intrauterine pregnancy and can order ultrasound when >DZ If not doubling appropriately consider treatment for ectopic (methotrexate or surgery)
Slide 11-

Now you know location…now what? An ectopic pregnancy can be treated either medically with methotrexate or surgically The next step with an intrauterine pregnancy is determining viability…
Slide 12-

Viability When you have an intrauterine pregnancy there are several possibilities 1- Normal 2 - Miscarriage (there are different types!) 3 - Molar pregnancy A viable pregnancy is an intrauterine pregnancy that has cardiac motion-should see by 7-8 weeks
Slide 13-

Intrauterine pregnancy First finding on US is an empty gestational sac But cannot say that it is an intrauterine pregnancy until you see a yolk sac or a fetal pole
Slide 14-

Intrauterine Pregnancy
Slide 15-

Yolk sac by 5 weeks www.advancedfertility.com
Slide 16-

Fetal Pole by 6-7 weeks www.advancedfertility.com
Slide 17-

Types of nonviable intrauterine pregnancies Anembryonic (blighted ovum) Threatened abortion Inevitable abortion Complete abortion Missed abortion
Slide 18-

Anembryonic gestation No yolk sac or fetal pole Mean gestational sac diameter of 30 mm www.gloriaspregnancyinfo.com
Slide 19-

Threatened abortion First trimester bleeding Fetal pole with a heartbeat If there is a heartbeat there is less than 10% chance of miscarriage
Slide 20-

Inevitable abortion Deformation and/or descent of gestational sac with a dilated cervix
Slide 21-

Complete abortion Products of conception completely expelled
Slide 22-

Missed abortion Intrauterine pregnancy with an embryo, but no cardiac activity by 8 weeks gestation
Slide 23-

Now you know the basic issues in early pregnancy!!
