Study Objective: To investigate the safety and efficacy of a single local methotrexate (MTX) injection for the treatment of cesarean scar pregnancy (CSP), assess reproductive outcomes after treatment, and confirm clinical outcomes after the treatment of CSP patients according to the presence of fetal cardiac activity or serum human chorionic gonadotropin (hCG) levels.
Design: A retrospective cohort study.
Setting: A university hospital.
Patients: Women with CSP.
Interventions: Single local MTX injection under transvaginal ultrasound guidance.
Measurements And Main Results: A total of 45 CSP cases were identified; the mean (standard deviation, range) estimated gestational age was 7.7 (1.7, 5.4-12.5) weeks and the mean serum hCG level was 51 801 (40 761, 2307-187 898) mIU/mL. Three cases required additional treatment with MTX, and none of the cases needed uterine artery embolization or hysterectomy. The success rate for a single dose was 93.3%, and it was 100% if additional treatments with MTX were included. The mean time required for hCG normalization in those with fetal cardiac activity or with an initial level of hCG greater than 100 000 mIU/mL was not significantly longer than that in the controls (93.4 vs 77.1 days, p = .12; 113.7 days vs 83.6 days, p = .10). Of the 23 women who desired a subsequent pregnancy, 13 delivered 14 healthy newborns after treatment, 3 had an ongoing pregnancy, and 3 experienced recurrent CSP.
Conclusions: A single local MTX injection is safe and effective for the treatment of CSP despite the presence of fetal cardiac activity or any initial level of hCG and may allow the possibility of a subsequent uneventful pregnancy.
