Transcervical extraamnial Rivanol instillation (TERI) was performed on 400 women. A Foley catheter was inserted through the cervical canal between the uteral wall and the amniotic cavity. 60-120 ml of .1% Rivanol was then instilled extraamnially, depending on the length of pregnancy. After 24 hours, the cervical canal had dilated spontaneously up to Hegar 12, allowing vacuum aspiration without danger of cervical lesions. 13% of the 400 abortions were performed by vacuum aspiration without TERI on nulliparae less than 8 weeks pregnant. TERI with spontaneous expulsion was used in 9% of the cases, for pregnancies after the 12th week. Hysterectomy was performed in 5% of the cases, and in the remaining 73%, TERI and vacuum aspiration were performed. A complication rate of 7.75% was reported: 1 cervical lesion, 7 cases of inflammation of the pelvis minor, 14 cases of bleeding in excess of 400 ml, and 9 cases of fever above 38 degrees C. This method shows advantages over Hegar dilatation or prostaglandin-induced abortion.
