Abstract

Annotatsion. The cardiac output closely correlated to the cardiac compliance and flow resistance indices at arterial and venous level. The acceleration time in the fetal arteries increased with advancing gestation in AAO, PA, MCA and DAO, but it decreased in RA and kept constant in UA. In addition, the acceleration time of UA was unrelated to cardiac output. The changes of the fetal intracardiac, arterial and venous impedances were remarkable through the gestation and related to cardiac output. Fetal cardiac output correlated well with the changes of arterial resistance, except with the DAO. The ventricular compliance increased with advancing gestation, especially in the left side, and was highly related to the change of cardiac output.  Diagnosis of intrauterine growth retardation (IVD), as a consequence of chronic kidney disease, is one of the most difficult in obstetric practice. In almost 60% of cases, fetal ASD is not detected by clinical methods. Without the use of additional examination methods, only 25% of cases of fetal ASD can be diagnosed, and if ASD is suspected during further examination, the diagnosis is confirmed in one of the three pregnant women.
