title: [Use of high-speed ultrasonography for differential diagnosis of gestational haemorrhage, following formation of placenta (author's transl)].
abstract: The "Vidoson 635-S" high-speed ultrasonographic unit was used by the authors to examine 465 women pregnant in the second and third trimenons for the occurrence of bleeding. The following findings were obtained: NAD (no abnormality discovered), Placenta praevia totalis, Placenta praevia partialis lateralis, Placenta praevia partialis marginalis, deep adherence of placenta, early detachment of placenta, and uterus rupture. - Placental displacement was observed by repeated checking in 57 of 196 placentas with pathological findings. Placental prolapse observed between the twelfth and 20th weeks of pregnancy was defined as "early" Placenta praevia, and the birth canal was left in about 50 per cent of those cases. The authors' view about such phenomenon was that while the point of placental adherence was unchanged, some change was undergone by the uterus wall of which that part changed position to which the placenta adhered, the latter dislocation being caused by enlargement of the upper third of the passive uterus region and its part in the formation of the uterus cavity.
