Early intervention for heterotopic caesarean scar pregnancy to preserve intrauterine pregnancy may improve outcomes: a retrospective cohort study

Heterotopic Cesarean Scar Pregnancy: A Case Report

Heterotopic pregnancy is a rare condition with an intrauterine pregnancy coexisting with extrauterine pregnancy. It is considered a rare condition, with an incidence of one in 30,000 spontaneous pregnancies. Because of its rarity, there are no international management guidelines. It is associated with increased maternal morbidity and mortality. Heterotopic pregnancy is a challenging condition to diagnose because it can be missed due to the intrauterine pregnancy. The most common signs and symptoms to support and help us reach a diagnosis would be adnexal mass, abdominal pain, and enlarged uterus. In this case report, we aim to compare the clinical course and the outcome of intrauterine gestation while coexisting with scar pregnancy and the management options. This case report concerns a 34-year-old pregnant woman with a heterotopic pregnancy managed in Bahrain Defence Force Hospital.

Fetal Reduction by Potassium Chloride Infusion in Unruptured Heterotopic Pregnancy: A Comprehensive Review

This comprehensive review explores the practice of fetal reduction through potassium chloride infusion in unruptured heterotopic pregnancies. Heterotopic pregnancies, characterized by the simultaneous occurrence of intrauterine and extrauterine gestations, present unique challenges in reproductive medicine. The review defines fetal reduction and underscores its significance in mitigating risks associated with heterotopic pregnancies, including the threat of rupture, maternal morbidity, and adverse outcomes. The analysis encompasses the background, methods, efficacy, ethical considerations, and future directions related to the procedure. Findings highlight the efficacy and safety of potassium chloride infusion, emphasizing the importance of proper patient selection and counseling. Implications for clinical practice underscore the procedure's viability in specific cases where the benefits outweigh the associated risks. The review concludes with recommendations for future studies, encouraging further research on procedural techniques, alternative methods, and the psychosocial impact on patients. This work is a foundation for advancing the management of unruptured heterotopic pregnancies, providing insights for clinicians and researchers to improve clinical outcomes and patient care.

A study on the timing of uterine artery embolization followed by pregnancy excision for cesarean scar pregnancy: a prospective study in China

BACKGROUND

Cesarean scar pregnancy (CSP) remains a sporadic and special form of ectopic pregnancy in which the fertilized ovum is implanted on a previous cesarean scar within 12 weeks. This study aims to evaluate the optimal time interval between uterine artery embolization (UAE) and curettage modalities in order to provide the best clinical outcomes.

METHODS

From January 2018 to December 2020, we recruited 61 patients with CSP. They were randomly divided into two groups depending on whether the time interval between UAE and dilatation and curettage (D&C) requires additional hospitalization: 31 patients received prophylactic UAE followed by D&C on the same day (0-12 h; group A) and 30 patients need hospitalization (12-72 h; group B). The clinical characteristics, diagnostic data, and outcomes of the two groups were compared and analyzed.

RESULTS

A total of 59 (96.72%) cases had responded well to the first treatment. One patient in each arm undergone retreatment, but none of the 61 patients needed additional hysterectomy. There was no considerable relationship between the two groups with respect to the intraoperative hemorrhage during D&C, serum index (containing β-hCG, hemoglobin, CRP, and D-dimer) on the first day after D&C, side effects (containing fever and abdominal pain), renal, hepatic, and coagulation function, time of CSP residual mass disappearance, and hospitalization cost. The time of serum β-hCG resolution after surgery was 41.22 ± 14.97 days in group A and 66.67 ± 36.64 days in group B (P = 0.027), and group A treatment resulted in a shorten hospital stay as compared with group B (4.81 ± 2.74 days vs. 6.80 ± 2.14 days, P <  0.001). However, the average hourly serum β-hCG decrease rate within 24 h and the leukocytes on the first day after D&C in group B were superior than in group A (P <  0.050).

CONCLUSION

For patients with CSP, UAE followed by D&C on the same day (0-12 h) appears to have more advantages in hospitalization and recovery time, while the long time interval (12-72 h) may have a lower risk of inflammation and a more rapid decrease in serum β-hCG level within 24 h after D&C surgery. The treatment of CSP should be individualized based on the conditions of patients.

Management of heterotopic cesarean scar pregnancy with preservation of intrauterine pregnancy: A case report

BACKGROUND

Heterotopic cesarean scar pregnancy (HCSP) is very rare and has a high risk of massive uterine bleeding. Preservation of concurrent intrauterine pregnancy (IUP) is one of the great challenges in the management of HCSP. No universal treatment protocol has been established when IUP is desired to be preserved.

CASE SUMMARY

We report a case of HCSP at 8⁺ wk gestation in a 34-year-old woman with stable hemodynamics. A two-step intervention was applied. Selective embryo aspiration was performed first, and surgical removal of ectopic gestational tissue by suction and curettage was performed 2 d later. Both steps were performed under ultrasound guidance. The patient had an uneventful course, and a healthy baby was delivered at 34⁺⁶ wk gestation.

CONCLUSION

Selective embryo aspiration followed by suction and curettage was successful in the preservation of IUP in the management of HCSP. This approach is an alternative option for HCSP in the first trimester when the IUP is desired to be preserved.
