Microwave endometrial ablation and pregnancies: case series

Induction of abortion following radiofrequency ablation of the endometrium: A case report and search for evidence-based practice

OBJECTIVES Pregnancy following endometrial ablation is a rare event that carries significant risks to the mother. The majority of women elect to terminate such pregnancies. This brings into question which of the available methods should best be employed and what kinds of problems to anticipate. CASE We present a case of a pregnancy following radiofrequency endometrial ablation that was terminated surgically and review the relevant English literature. CONCLUSIONS Medical or surgical abortion can be considered as primary methods of terminating a first trimester intrauterine pregnancy following endometrial ablation. The choice will depend on patient preference but also on the available expertise. Cervical stenosis and/or intrauterine adhesions may limit the effectiveness of these methods. In such cases methotrexate is an alternative option, whereas hysterotomy or hysterectomy should be considered as final options. Counselling patients at the time of endometrial ablation regarding the need for contraception, even after prolonged periods of amenorrhoea is of paramount importance. Laparoscopic or hysteroscopic sterilisation can be offered together with endometrial ablation.

Treatment with methotrexate of a cornual pregnancy following endometrial resection

OBJECTIVES

Endometrial resection is a procedure often performed for treatment of menorrhagia. Despite the fact that amenorrhoea frequently ensues, some normal endometrium can remain present and become the implantation site of a pregnancy. Such an event is uncommon (0.7%); however, the likelihood of an ectopic pregnancy is increased. This case report calls the reader's attention to the risk of intra- and extrauterine pregnancies and the necessity for contraception after endometrial resection, even in cases where amenorrhoea supervenes.

CASE

A 46-year-old woman with prior endometrial resection and subsequent amenorrhoea, was diagnosed with a cornual pregnancy. She was successfully treated with systemic methotrexate, which was given in an outpatient clinic.

CONCLUSION

Clinicians should be aware of the increased likelihood of an ectopic pregnancy after endometrial resection. All women submitting to this procedure should be counselled about the need for contraception, even in cases where amenorrhoea develops.
