[Practical aspects of Doppler sonography in obstetrics].

Doppler sonography has become a principal diagnostic method of antenatal care in Hungary during the past decade. Consequently, the perinatal outcome of high-risk pregnancies has significantly improved. Evaluation of the fetal circulation facilitates clinical diagnosis, antenatal and subnatal fetal surveillance, arrangement of functional tests and optimal timing of delivery. Advanced clinical efficacy is based on identical practical aspects and standardized routine. Based on their clinical experience and the published scientific data authors propose practical guidelines for Doppler evaluation of the uteroplacental and the fetal arterial and venous circulation. Summary of the blood flow velocity waveform analysis, and the steps of useful application offer consistent clinical comprehension and proper diagnosis.
