The Value of Hysterosalpingography following Medical Treatment with Methotrexate for Ectopic Pregnancy.

After an ectopic pregnancy (EP) fertility decreases, mostly due to tubal factor. Hysterosalpingography (HSG) is the most cost-effective tool for tubal patency assessment. Objective. To evaluate the usefulness of a HSG after a medical treatment for an EP, in order to counsel women on the most appropriate way to conceive future pregnancies. Methods. Between 1998 and 2008, 144 patients were submitted to medical treatment for an EP and performed HSG 3 months after the event. Results. 72.2% of normal HSG, 18.8% with unilateral obstruction, 6.3% tubal patency with defect, and 2.8% bilateral obstruction. Conclusion. Routine HSG following medical treatment for an EP does not seem necessary, as it does not change the initial management in 97.2% of the cases, but might be considered in selected risk cases, permitting timely referral of patients to in vitro fertilization.
