Midtrimester abortion induction with intraamniotic prostaglandin F2 alpha in women with previous uterine surgery.

Of 207 women who underwent midtrimester induced abortion with intraamniotic prostaglandin F 2 alpha instillation, 30 (14.5%) had had one or more previous uterine operations. Multivariate analysis showed no correlation between a previous uterine operation and the hospitalization length, procedure complication rate or length of the injection-delivery interval (IDI). The IDI was similar in patients with and without a previous uterine operation. No case of uterine rupture occurred. Intraamniotic prostaglandin instillation for midtrimester abortion induction seems to be an effective procedure without severe complications in women with previous uterine operations.
