Transplacental Haemorrhage Due to Termination of Pregnancy

Summary The incidence of transplacental haemorrhage has been estimated in 200 women undergoing termination of pregnancy. Vaginal termination by curettage or vacuum aspiration carried a 25 per cent risk of transplacental haemorrhage determined by acid elution. Similarly, hysterotomy carried a 23 per cent risk. Hysterectomy or intra‐amniotic injection of glucose were less likely to cause transplacental bleeding. One rhesus negative patient showed a rapid rise in incomplete anti‐D six months after termination by curettage.
