Hello,I am 28 years old and 18 weeks pregnant. Recently I have done Gravid Uterus - Obstetric Sonography and found the below result. Placenta is posterior, grade I, low lying - lower end is about 25 to 35 mm from internal OS. Left uterine artery shows high resistance flow. So, I wanted to know if there is any issue. What precautions should I take as I am doing routine work as housewife. I have also attached my sonography report. Please have a look and let me know what need to be done and what should be taken care of, as I am tensed.
Hello. I have gone through your reports (attachment removed to protect patient identity). This level 2 anomaly scan is absolutely normal for the foetus pertaining to its growth and absence of any congenital anomalies.  The concern regarding the low lying placenta at 18-19 weeks of gestation is not alarming as by 32 -36 weeks the placenta tends to go up once the lower segment formation takes place over uterus. Low lying or placenta previa shall be considered then at 32-36 weeks if the distance is less than 25 mm from internal os. High resistance flow in left uterine artery alone indicates a possible compression or hindrance in blood supply. There may be a subserosal fibroid or enlarged ovary probably which can cause external compression , but it is unlikely to affect the baby's growth as the other arterial flow is normal. At present this just needs to be followed up by a repeat uterine artery doppler after a month to check the same or increase in resistance flow.
