Summary
Cesarean scar pregnancy can be diagnosed with transvaginal color Doppler sonography. Ultrasound-guided methotrexate injection is the preferred treatment to preserve fertility, while invasive methods carry high risks.
Area of Science:
- Reproductive Medicine
- Obstetrics & Gynecology
- Diagnostic Imaging
Background:
- Cesarean scar pregnancy is a rare form of ectopic pregnancy.
- It occurs when a pregnancy implants within the myometrium at the site of a previous Cesarean section scar.
- Early diagnosis and appropriate management are crucial for fertility preservation.
Purpose of the Study:
- To evaluate the diagnostic and treatment experience of Cesarean scar pregnancy.
- To assess the efficacy of conservative management strategies, particularly ultrasound-guided methotrexate injection.
- To compare outcomes with more invasive surgical interventions.
Main Methods:
- A retrospective review of 12 Cesarean scar pregnancy cases over 6 years.
- Diagnosis was confirmed using transvaginal color Doppler sonography.
- Treatment methods included methotrexate injection (ultrasound-guided or systemic), dilatation and curettage, and local resection.
Main Results:
- The incidence of Cesarean scar pregnancy was 1:2216.
- Eleven of 12 patients successfully preserved reproductive capacity with conservative treatment.
- Ultrasound-guided methotrexate injection resulted in successful outcomes with minimal complications.
Conclusions:
- Ultrasound-guided methotrexate injection is the treatment of choice for Cesarean scar pregnancy.
- Invasive surgical methods like dilatation and curettage are associated with high morbidity and should be avoided.
- Conservative management effectively preserves fertility in most Cesarean scar pregnancy cases.
