  • Title: [Uteroplacental circulation in growth retardation--experiences with the clinical use of continuous-wave Doppler].
    Author: Hütter W, Grab D, Beusch P, Terinde R, Wolf A.
    Journal: Wien Klin Wochenschr; 1992; 104(23):709-13. PubMed ID: 1475979.
    Abstract:
    Doppler ultrasound measurement of blood flow velocity represents a non-invasive method of studying uteroplacental and feto-placental haemodynamics. Using a continuous-wave Doppler device, the blood flow velocity was examined in the uterine and arcuate arteries, as well as in the umbilical artery in 81 patients demonstrating fetal growth retardation. An increase in vessel resistance was found in the uterine and arcuate arteries in most of the patients. In addition, patients with fetal retardation showed a significantly higher rate of diastolic notching and incomplete registration of uterine and arcuate wave forms, especially in pregnancies complicated by hypertension. The implementation of the continuous-wave technique as a simple Doppler system allows differential evaluation of placental function and provides information on the nutritional supply to the fetus.
