Summary
Brief summary
The study included a control and a study group each 30 cases with history of unexplained recurrent abortion. The control group was treated with folic acid tablet 0.5 mg once daily orally and the study group treated with folic acid plus isosorbid mononitrate 20 mg given vaginally. Treatment was given monthly from day 21-23 of the cycle until menstruation and continued if pregnancy occurred until 20 weeks gestation. Doppler ultrasound was done vaginally before treatment and abdominally at 20 weeks gestation to measure uterine artery resistance and pulsation indices. Patients were treated until 20 weeks gestation to compare uterine artery indices before and after treatment and the incidence of abortion in both groups
