Abstract

Abstract Failure of first trimester pregnancy termination is an uncommon, although potentially serious complication of attempted therapeutic abortion. We report our ex-perience in four patients with unsuspected congenital uterine anomalies in whom at-tempted pregnancy termination procedures failed to completely ablate the products of conception. When dilatation and curettage fails to produce embryonic tissue, sonog-raphy is indicated to exclude ectopic gestation or uterine anomaly. In patients who are known to have anomalous uteri, intraoperative real-time guidance may increase the success of pregnancy termination procedures and decrease the incidence of retained products of conception.
