Transvaginal ultrasound demonstrated a gestational sac (GS) with an embryo and crown rump length correlating with 7 weeks 6 days GA implanted in the cervical stroma (Figure 1).

The vaginal balloon was inflated to 60 ml in the cervix directly over the GS while visualizing compression of the GS on transabdominal ultrasound (Figure 2). 72 hours after the procedure, the cervical ripening balloon was removed under ultrasound guidance.
Transabdominal and sagittal ultrasound 12 weeks after removal of balloon demonstrating GS decreased to 1.4 cm.

GS measured to be 6.5 cm and the patient reported to have passed pregnancy tissue at home. GS diameter measured 4 cm at 7 weeks, and finally, 1.4 cm at 12 weeks (Figure 3) with nonpregnant beta-hCG levels (<5 mIU/ml).
