[Spontaneous vaginal delivery in a case of total placenta previa (author's transl)].
In a 26 year old gravida 2, Para O, Aborta 1, a total placenta previa was diagnosed at 30 weeks gestation in an ultrasound tomogram. A repeat ultrasound examination 9 weeks later showed no more placenta previa in front of the cervix. This was at first interpreted as a change in the site of the placenta during the pregnancy. During the spontaneous labour the contractions, fetal heart rate and the intermittent scalp pH were monitored. A spontaneous vertex presentation delivery of a normal infant through the placenta resulted. Microscopic examination of the placenta showed a central defect with wide marginal infarcts probably due to compression atrophy by the presenting part.
