Hello Thank you for the query. Uterine artery notching is sometimes a normal finding at 22 weeks, but it can be a predictor of gestational hypertension later on. Also remember that the more important finding is that the baby is not growing properly You need to attach the entire ultrasound and doppler report for me to comment better. Also, causes of such a report could be genetic defects within the baby, problems in the placenta, maternal diseases like diabetes, hypertension or other chronic conditions. You should improve your diet - increase your fluid intake, protein intake and take regular supplements as advised. take care.
