Abstract
Objective: To evaluate the correlation between Umbilical Artery (UA) Doppler and its feasibility across categories of maternal BMI in the presence of foetal growth restriction (FGR). Methods: 1074 Singleton pregnancies with suspected FGR on ultrasound examination between 24+0 and 36+0 weeks' gestation were reviewed. Evaluation of the UA Doppler was performed at 1‐2 weekly intervals. Abnormal UA Doppler findings and delivery outcomes were compared between the different maternal BMI categories. Results: Increased UA pulsatility index (PI > 95th centile) was reported in 81% of obese category 2 patients (BMI <35 ‐ 39.9 kg/m2) compared to a 46% incidence in the remaining categories, normal (BMI <24.9 kg/m2), overweight (BMI <25 ‐ 29.9 kg/) and obese class 1 (BMI <35 ‐ 39.9 kg/m2) (p = 0.001). In absent or reversed end diastolic flow (AEDF/REDF) we found an increasing incidence across the BMI categories (4%‐25%) (p<0.0001). Higher maternal BMI was associated with Lower birthweights and higher C‐section rates. Increasing maternal BMI did not affect successful assessment of UA Doppler. Conclusion: There is a positive correlation between increasing maternal BMI and abnormal UA Doppler findings in FGR. Maternal BMI may be considered as an additional risk factor when evaluating UA Doppler for placental insufficiency.
