RESULTS:BUACE was technically successful and immediate haemostasis was achieved in all patients. Blood loss was significantly greater during D&C undertaken before BUACE compared with D&C after BUACE, but this bleeding was controlled by BUACE. No patient required further surgical intervention and there were no severe complications. The gestational sac and placenta could no longer be detected ultrasonographically and the menstrual cycle returned to normal 2 -3 months after treatment in all patients. CONCLUSIONS: BUACE followed by D&C seems to be a safe and effective treatment for CSP and should be considered as a treatment of choice.
