Ectopic Pregnancy Overview

Ectopic Pregnancy Overview

• An ectopic pregnancy occurs when a fertilized egg implants outside the uterus, most commonly in a fallopian tube.
• This condition results in a non-viable pregnancy and poses significant risks to the pregnant individual, necessitating termination.

Diagnosis

• The fertilized egg fails to migrate properly to the uterus, leading to abnormal implantation.
• Locations other than the uterine lining where implantation can occur include:
  • Ovary: Cannot sustain a pregnancy due to insufficient tissue support.
  • Abdomen: Extremely rare and highly dangerous with no conducive environment for fetal development.
  • Interstitial: Relevant to a section of the fallopian tube that penetrates the uterus, posing severe bleeding risks if ruptured.
  • Fallopian Tube (Tubal Ectopic): Most common site for ectopic pregnancies, leading to rupture as it cannot expand like the uterus.
  • Cervix: Can cause significant bleeding as it is not designed for fetal implantation.

Signs and Symptoms

• Positive pregnancy test indicating rising hCG (human chorionic gonadotropin) levels, despite abnormal implantation.
• Abdominal pain resulting from tissue damage or stretching around the implantation site.
• Bleeding due to damaged surrounding tissues from abnormal implantation.
• Ultrasound may reveal an empty uterine cavity despite positive pregnancy test results.

Lab Evaluation

• Ultrasound serves as the critical tool for determining the pregnancy's location and confirming an ectopic pregnancy requiring immediate medical intervention.

Management

• Early termination of the ectopic pregnancy prevents life-threatening ruptures and internal bleeding.
• Medication: Methotrexate is utilized to terminate the pregnancy by stopping cell division without surgery in early cases.
• Surgical Options:
  • Laparoscopy: Incision in the affected tube to remove the ectopic pregnancy while preserving surrounding organs.
  • Removal of Affected Tube: Necessary if the fallopian tube is severely damaged to prevent future complications.

Timing and Birth Considerations

• Termination of an ectopic pregnancy is essential; continued growth increases rupture risks leading to fatal hemorrhage.
• Types of birth (vaginal vs. C-section) are not applicable since the pregnancy is terminated.

Risks to the Fetus

• A developing fetus outside the uterus will not survive due to lack of essential support and environment.

Risks to the Pregnant Individual

• A ruptured ectopic pregnancy can cause severe internal hemorrhage, necessitating surgical intervention to prevent further complications.
• Removal of the ruptured organ (e.g., fallopian tube) can still allow future pregnancies through the other functional tube.

Risk Factors for Ectopic Pregnancy

• Pelvic Inflammatory Disease (PID): Scarring may obstruct normal zygote passage, increasing ectopic risk.
• Previous Ectopic Pregnancy: Past incidents may lead to higher recurrence probability due to potential anatomical damage.
• Pelvic or Abdominal Surgery: Surgical procedures may leave scarring obstructing zygote movement.
• Endometriosis: The presence of endometrial tissue outside the uterus can distort reproductive anatomy, raising ectopic implantation chances.
