Comparison of menstruation recovery after ultrasound-guided suction curettage in patients with cesarean scar pregnancy pretreated using high-intensity focused ultrasound and uterine artery embolization.

OBJECTIVES

To investigate the menstruation recovery after two therapeutic regimens, high-intensity focused ultrasound (HIFU) or uterine artery embolization (UAE) combined with ultrasound-guided suction curettage, for premenopausal women with cesarean scar pregnancy (CSP).

MATERIALS AND METHODS

Seventy patients with CSP treated with HIFU followed by ultrasound-guided suction curettage and 63 patients with CSP treated with UAE followed by ultrasound-guided suction curettage in our hospital were retrospectively reviewed. The treatment parameters and the menstrual blood loss (MBL) volume at 6 months after the two therapeutic regimens were compared between the two groups.

RESULTS

There was no significant difference in treatment results between the two groups. With regard to postoperative MBL volume, 5 out of 70 patients in the HIFU group and 22 out of 63 patients in UAE group exhibited a reduction in MBL, respectively. Multivariate logistic regression revealed that hypomenorrhea was more likely to occur in the UAE group than in the HIFU group (UAE group vs. HIFU group; OR 11.328, 95% CI 3.158-55.871;  < 0.001).

CONCLUSION

Compared to UAE, HIFU has less influence on postoperative MBL volume, which may be a fertility-sparing option for patients with CSP.
