Q

What is the most common location for Ectopic Pregnancy?

A

Fallopian tubes

This is where most ectopic pregnancies occur.

17
Q

What are the risk factors for Ectopic Pregnancy?

A
  • Documented tubal pathology (PID)
  • Surgery to restore tubal patency
  • Tubal sterilization
  • Prior ectopic pregnancy (10-16x)
  • Smoking (>1ppd) (3-4x)
  • Advanced maternal age (35-44 y/o) (3x)
  • Intrauterine devices (IUD)

These factors significantly increase the risk of ectopic pregnancies.

18
Q

What is the classic triad of symptoms for Ectopic Pregnancy?

A
  • Amenorrhea
  • Vaginal bleeding
  • Ipsilateral abdominal pain
19
Q

What additional symptoms may present in Ectopic Pregnancy?

A
  • Breast tenderness
  • Nausea
  • Urinary symptoms
  • Shoulder pain (referred)
  • Vertigo
  • Syncope (hemorrhagic hypovolemia)
20
Q

What is the gold standard for diagnosing Ectopic Pregnancy?

A

Diagnostic laparoscopy

21
Q

Which laboratory tests are used in the workup for Ectopic Pregnancy?

A
  • Serum beta-hCG level
  • Urine beta-hCG level
  • Transvaginal ultrasound
  • Transabdominal ultrasound
  • Culdocentesis
22
Q

What is the medical management for a stable Ectopic Pregnancy?

A

Methotrexate

It is a folic acid antagonist that inhibits dihydrofolate reductase.

23
Q

What does Methotrexate lead to in the treatment of Ectopic Pregnancy?

A

Arrest of DNA, RNA, and protein synthesis due to reduction of purines and thymidylate

24
Q
