BACKGROUND: This study was conducted to evaluate the effect of levonorgestrel-releasing intrauterine devices (LNG-IUDs) on menorrhagia in patients receiving anticoagulant therapy after cardiac valve replacement. STUDY DESIGN: Forty women with menorrhagia who underwent cardiac valve replacement and were taking anticoagulant medication were enrolled in the study. The women were randomly divided into two groups: LNG-IUDs were inserted into 20 women in Group 1 over the first 3 days of menstrual bleeding, while the women in Group 2 were followed without any intervention. The activated partial thromboplastin time, prothrombin time, international normalized ratio, hematocrit level, hemoglobin level, ferritin level and pictorial bleeding assessments for the quantity of menstrual bleeding were recorded. RESULTS: Three months after insertion of LNG-IUDs, the women in Group 1 had a significant decrease in blood loss and higher hemoglobin, hematocrit and ferritin values. No difference was detected for these parameters in the control group at the third and sixth months of the study. Coagulation parameters did not differ between the two groups. CONCLUSION: LNG-IUDs can be considered as an effective non-surgical treatment for menorrhagia in women receiving anticoagulant therapy after cardiac valve replacement.
