This case series describes changes in size, vascularity, and cul-de-sac fluid in 30 patients with ectopic pregnancies who were treated with systemic methotrexate. Pretreatment and posttreatment transvaginal sonography of the ectopic pregnancies was performed with color Doppler imaging, and the images were assessed for changes in size, vascularity, and cul-de-sac free fluid. There was a trend for nonresponders to show increased vascularity on serial examinations, although this finding was also seen in a single responder. There was also a trend for nonresponders with increased vascularity to be associated with a greater increase in β-human chorionic gonadotropin levels and responders with decreased vascularity to be associated with a greater decrease in β-human chorionic gonadotropin levels.
