What Is Meant By RI Of 0.88 In Ultrasound Of Pregnancy?
Dear Doctor, I am 34 yrs old and 17.4 wks pregnant. My level- 1 ultra sound was done whem i was 11.4 wks. My report of that ultrasound says maternal left uterine artery shows mildly increased impedance to flow and with a RI of 0.88 and maternal right uterine artery shows normal flow and with a RI of 0.77 and fetal ductus venosus shows a normal flow with S/A ratio of 4.15 . Babys heart beat was 167bpm Crown - rump length was 48.2mm and Nuchal translucency was 1.1mm. Placenta is on rt. wall its inferior limit located 29mm superior to the internal OS. My ObGYN started EcoSpirin 75 once daily since then. Will you please tell me how does this impedence to flow effects baby or me ? If I am on right medication? If my placenta is in normal position? Also my level 2 ultrasound is due during 19.1 wk, so will this problem subside by then?? what precautions should i take?

I don't know why colour doppler was done at this gestation age. did you have some complication regarding pregnancy. We generally prescribe colour doppler after 32 week that too in complicated pregnancy not in all cases. Moreover resistance is common at this gestation age so don't worry. ecospirin is fine continue with this.
