[Late postpartum hemorrhage].

In the presented material the frequency of postpartum haemorrhage is 0.74%. In the study sixty-nine histologically confirmed cases were considered. At histological examination three main factors were found--subinvolution of the placental site, retained placental tissue, and inflammation, each of them responsible for about one third of all cases. The possible influence of such factors as parity, time of delivery, frequency of caesarian section, frequency of intrauterine exploration, manual extraction of the placenta, and induction and stimulation of the delivery on late postpartum haemorrhage is discussed.
