Introduction
There is no such thing as "the safest way to abort a cesarean scar pregnancy." To ensure a safe termination of a cesarean scar pregnancy, it is essential to conduct thorough preoperative evaluation, choose appropriate medical pretreatment, perform the procedure under ultrasound guidance, closely monitor vital signs during surgery, and follow standardized postoperative follow-up protocols. The entire process must be carried out in a professional medical facility, and self-management is strictly prohibited. If heavy vaginal bleeding or severe abdominal pain occurs, immediate medical attention is recommended.
There is no such thing as "the safest way to abort a cesarean scar pregnancy." For safe termination of a cesarean scar pregnancy, it is essential to undergo preoperative evaluation, use medication for pretreatment, perform ultrasound-guided surgery, monitor vital signs during the procedure, and follow standardized postoperative follow-up. The entire process must be conducted in a professional medical facility—self-management is strictly prohibited. If heavy vaginal bleeding or severe abdominal pain occurs, seek immediate medical attention.
1. Preoperative Evaluation: Use ultrasound and serum hCG testing to confirm the location of the pregnancy, assess the condition of the uterine scar, and determine embryonic viability. This helps evaluate the risk of bleeding and provides the basis for developing a treatment plan—it is a fundamental step in ensuring safety.
2. Medical Pretreatment: Medications such as methotrexate are commonly used to suppress embryonic activity and reduce the risk of bleeding during surgery. This approach is especially suitable for cases with larger embryos or higher serum hCG levels. Medication must be taken as prescribed, with close monitoring of drug response.
3. Ultrasound-Guided Surgery: Perform dilation and curettage (D&C) or hysteroscopic surgery under real-time ultrasound guidance to precisely locate the embryo, avoid damaging the cesarean scar tissue, and minimize complications such as uterine perforation and massive hemorrhage.
4. Intraoperative Monitoring: Continuously monitor vital signs—including blood pressure, heart rate, and oxygen saturation—throughout the procedure. Have blood transfusion equipment and emergency medications ready to promptly manage potential intraoperative emergencies such as hemorrhage or shock.
5. Postoperative Follow-Up: Regularly monitor serum hCG levels after surgery until they return to normal. Use ultrasound to evaluate healing of the uterine scar and check for residual tissue or poor scar healing, addressing any abnormalities promptly.
After surgery, rest in bed for 1–2 weeks and avoid physical strain and strenuous activity. Eat a diet rich in protein to promote recovery. Maintain good external genital hygiene, and refrain from sexual intercourse and tub baths for a short period to prevent infection.
