Abstract:
Objective To evaluate Doppler spectrum of ductus venosus(DV) in selective intrauterine growth restricted(sIUGR) pregnancies.Methods Thirty-five sIUGR pregnancies and 35 normal single pregnancies with same gestational week were enrolled,there were 10 sIUGR Ⅰ,13 sIUGR Ⅱ and 12 sIUGR Ⅲ in sIUGR.Spectrum of ductus venosus,such as DV S wave,DV D wave,DV A wave,DV PI,DV PLI and S/A were assessed.Results ① There was no significantly difference in spectrum of ductus venosus between bigger of sIUGR,smaller of sIUGR Ⅰ with normal fetus (all P ＞0.05).② Compared with normal fetus,DV-PI,DV-PLI and S/A were significant higher in smaller of sIUGR Ⅱ and sIUGR Ⅲ (P ＜0.05);DV-S wave,and DV-D wave showed no significantly difference in smaller of sIUGR Ⅱ and sIUGRⅢ (P ＞0.05).Conclusions Spectrum of ductus venosus in bigger of sIUGR and smaller of sIUGR Ⅰ are mainly normal,and nearly in good condition in utero,inversely,abnormal spectrum of ductus venosus commonly exists in smaller of sIUGR Ⅱ and sIUGR Ⅲ,and supervision should be done carefully in these group.
