Therapeutic effects of uterine artery embolisation (UAE) and methotrexate (MTX) conservative therapy used in treatment of cesarean scar pregnancy.

PURPOSES

Cesarean scar pregnancy (CSP) is a rare and severe complication after cesarean section. The incidence of CSP has been increased significantly in recent years. In this retrospective case study of 131 CSP patients, the therapeutic effects and prognosis were compared between the two treatment groups: uterine artery embolization and systemic methotrexate injection conservative therapy. In addition, the necessary of subsequent dilation and curettage as a further treatment was also evaluated.

METHODS

The 131 CSP patients were assigned into two groups receiving uterine artery embolization (UAE) or MTX conservative therapy. Based on patients' myometrial thickness and reducing degree of β-hCG level, each of the two treatment group was further divided into two subgroups according to whether the patient received subsequent dilation and curettage as further treatment. The therapeutic effect of two treatment groups was compared.

RESULTS

The results indicated that both UAE and MTX conservative treatment achieved the expected therapeutic effect, and the recovery time in dilation and curettage subgroup was significantly shorter than that of the non-curettage subgroup. One hundred and thirty patients resumed normal menstrual cycles within 3-10 months after the treatment.

CONCLUSIONS

The individualized therapeutic regimen is an important factor to achieve the desired therapeutic effect based on the specific indications. Dilation and curettage could shorten the recovery time significantly.
