[Pathologic Doppler flow findings and cardiotocography results].
Of 1950 pregnant patients (2870 Doppler ultrasound measurements) we observed, in a study group with highly abnormal Doppler-flow findings (n = 66, Feb. 1990), a correlation of Doppler flow and FHR-recordings. Among these 66 patients we retained 60 (91%) in the hospital. They had at least 2 FHR-recordings a day. The results of Doppler flow measurements in the fetal aorta and umbilical artery correlated well with diagnosis of IUGR. The comparison of the overall results of both fetal vessels did not indicate any significant difference. In 21% of all patients with highly abnormal Doppler flow findings, was no abnormal FHR record until delivery. 26% already showed an abnormal non-stress test before the first pathological Doppler assessment, in 44% abnormal FHR-recordings were observed later than the first abnormal Doppler flow finding in the course of pregnancy. The median interval was 13.5 days in cases with increased Doppler flow parameters but with detectable end-diastolic blood flow and was reduced to 8 days in cases with absent end-diastolic blood flow. In 9% of all cases, abnormal results were found with both methods on the same day. In 32% we observed a reproducible notch in Doppler flow velocimetry of uteroplacental vessels. The rate of congenital malformations was 14%. Thus abnormal Doppler flow signals can be estimated as "early" prognostic criterias for a compromised fetus at risk.
