[Doppler findings--placental morphology: correlation and divergence of findings]

Based on 132 histomorphological placental investigations and their related Doppler test results, the question was asked, whether a strong correlation exists between Doppler test results and histomorphological placenta results, and whether these are uniform with respect to histomorphological changes. The results showed that all histomorphologically inconspicuous placenta findings were also inconspicuous doppler-sonographically. The viewing resulted in no histomorphologically unifying aspect of change. However, the investigation was able to demonstrate, that a distinction must be made between acutely developing changes and chronically developing changes. Along these lines, the last groups produced not only changes which compensate each other, but also changes, which are harmful to organic functioning and thus may diminish foetal supply without being detected by pulsed Doppler ultrasound.
