Summary
Ectopic pregnancy in a Cesarean scar can lead to uterine rupture. Early diagnosis and termination are recommended, except for superficial cases with ultrasound evidence of uterine cavity connection.
Area of Science:
- Reproductive Medicine
- Obstetrics & Gynecology
- Surgical Pathology
Background:
- Ectopic pregnancies, particularly those in Cesarean section scars, pose significant risks.
- Lower uterine segment scar defects can lead to deep myometrial implantation.
Observation:
- A case of ectopic pregnancy implanted within a lower uterine segment scar after a previous Cesarean section is presented.
- Deep implantation increases the risk of persistent pain, bleeding, and uterine rupture.
Findings:
- Management options for Cesarean scar ectopic pregnancy are discussed.
- Superficial implantation with ultrasound evidence of gestational sac continuity with the uterine cavity is a rare exception.
Implications:
- Strong recommendation for pregnancy termination in cases of deep Cesarean scar implantation.
- Highlights the critical need for early diagnosis and intervention to prevent life-threatening complications such as uterine rupture.
