[PI index value in fetal ductus venosus blood flow at 11-14 weeks in normal course of pregnancy].
OBJECTIVE
Development of ultrasound diagnostic with Doppler examination allows early and and more precise assessement of fetal anatomy and well-being.


METHODS
Evaluation of blood flow parameters in fetal ductus venosus between 11 and 14 weeks of pregnancy was performed.


METHODS
Fetal anatomy, nuchal translucency, nasal bone and ductus venosus blood flow has been studied with transabdominal probe in 225 consecutive fetuses according to Fetal Medicine Foundation recommendations.


RESULTS
From total number of 225 cases finally ten women were excluded from analysis due to absent or reversed A-wave in DV blood flow. In remaining 215 cases mean value of PI was 0,94 (range 0,53-1,88), mean value of Vmax (S-wave) was 42,48cm/s (range 18,7-102,9cm/sek), and mean value of Vmin (A-wave)--11,91cm/s (range 1,13- 37,32 cm/sek).


CONCLUSIONS
PI index value slightly decreased with increasing CRL. There was no differences in mean blood flow velocity with CRL for S-wave. A decrease in mean blood flow velocity with CRL was noted for A-wave.
