ABSTRACT
Objective To study the relationship between velocities of ductus venosus(DV),inferior vena cava(IVC) and right hepatic vein(RHV) of fetus,and abnormal perinatal outcome in high-risk pregnancy so as to find out which venous velocity can predict abnormal perinatal outcome and which velocity is the best for predicting abnormal perinatal outcome. Methods Velocities of DV,IVC and RHV in 67 cases of high-risk pregnancy were examined through color Doppler and their relationship with perinatal outcome was analyzed respectively. Results RHV-pulsatility index(PI) ,DV-pre-load index(PLl) ,DV-S/A and IVC-peak velocity index(PVI) could all predict abnormal perinatal outcome in high-risk pregnancy. But RHV-PI had the best prediction, and when its positive cutoff value was taken as 2. 89,the sensitivity for abnormal outcome was 75. 0% ,the specificity was 76. 7% ,and the correct index (Youden index) was 0. 52. Conclusions RHV-PI can best predict abnormal perinatal outcome in high-risk pregnancy,which can help a lot for prompt clinical treatment.
