[On the clinical significance of sequential scintigraphic examinations of the uteroplacental perfusion (author's transl)].
The utero-placental perfusion was examined by means of the method of Hünermann (1972) in a group of 74 patients with toxemia of pregnancy, diabetes mellitus, or intrauterine growth retardation. The perfusion measurements were categorized and evaluated according to the clinical findings. The correlation between single values deriving from the time-activity curves and their clinical predictive value was ascertained. A strong correlation between the parameters and the clinical findings resulted when several criteria were considered simultaneously. Among the single values resulting from the perfusion curves, the Tmax (placenta) and Tmax (uterus) (time of activity maximum) as well as the quotient of both revealed the highest significance. Pathological time-activity-curves were found in 16 of 19 patients with moderate and severe intrauterine growth retardation, and in all patients with moderate and severe toxemia, or diabetes mellitus. The limited clinical value of the used method is discussed.
