OBJECTIVES: The objective of the study was to estimate selected Fetal Pulmonary Artery blood flow parameters in pregnancies complicated by oligohydramnios in relation to normal pregnancies.
MATERIALS AND METHODS: A total of 52 patients between 26 and 39 weeks of pregnancy complicated by oligohydramnios due to: placental insufficiency, PROM or idiopathic etiology and 69 normal pregnancies were involved in the study. Ultrasound examination using color and pulse Doppler were made. Signal was obtained from distal part of right or left pulmonary artery at the level of four chamber view. The RI, PI and S/D ratio were estimated.
RESULTS: Significant increase in PI was observed in the group with severe oligohydramnios (AFI < 2.0 cm) compared to normal pregnancies. No significant differences were selected in RI and S/D ratio between mentioned groups.
CONCLUSIONS: The study showed deterioration in fetal pulmonary artery blood flow in pregnancies complicated by severe oligohydramnios.
