High-intensity focussed ultrasound and hysteroscopy endo-operative system cold device procedures for treating >4cm diameter FIGO Type 2 uterine myoma and ensuring successful pregnancy.

Purpose: Laparotomic or hysteroscopic myomectomy, and high-intensity focussed ultrasound (HIFU), can be used in the treatment of Type 2 myomas with a > 50% intramural component. Hysteroscopic electroresection may damage the remaining endometrium and complete ablation of myomas may not be realised via HIFU treatment. We report and examine the results of 1 case of HIFU treatment, accompanied with the hysteroscopy endo-operative system (HEOS) cold device procedure.

Materials and methods: These were used for treating a > 4cm diameter Type 2 uterine myoma and ensuring successful pregnancy. HIFU treatment of uterine myomas can achieve point-by-point ablation of lesions as far as possible without damaging the endometrium. The HEOS cold device procedure was implemented 3 months after HIFU treatment.

Results: The patient got pregnant naturally in the third month after receiving treatment, with no complications during her pregnancy. The patient gave birth to a healthy male via full-term cesarean section.

Conclusions: HIFU treatment, accompanied with the HEOS cold device procedure, ensured complete myoma removal. It also preserved the integrity of the myometrium and prevented uterine perforation during surgery.
