[Doppler-metric and Doppler echocardiographic study of the nature and stage of disorders of fetal hemodynamics in intrauterine fetal growth retardation].

Pregnancy course, labor outcome, and doppler-metric findings were analyzed in 174 women, 98 with normal pregnancy (controls) and 76 with small-for-date fetuses when examined on weeks 28-41; the aim of the study was to analyze the pattern of hemodynamic disorders in small-for-date fetuses. A classification of fetal hemodynamic disorders has been developed, that distinguishes three types of disorders differing in severity: first degree--disordered fetoplacental circulation not reaching the critical values and satisfactory fetal hemodynamics; second degree--compensated disorders of fetal hemodynamics; third degree--critical state of fetal hemodynamics. Use of this classification in clinical practice will help define rational strategy of pregnancy follow-up.
