[Injection of placental blood vessels: technique and the preliminary results (author's transl)].
The authors describe a technique for injecting the placenta, using an iodine contrast solution which allows a radiographic picture to be obtained. The vascular supply of the placenta can be shown up by this method accurately and cotyledons can be identified so that their number and their surface can be measured. The preliminary results show that there is a significant difference between the placentas of normal infants and of those with growth retardation. This should give rise to a new approach of the syndrome of intra-uterine growth retardation.
