RESUMO
OBJECTIVES: To understand the effect of 50-g oral glucose tolerance test (OGTT) on fetal celiac artery and superior mesenteric artery (SMA) Doppler parameters. METHODS: A total of 43 healthy pregnant women followed in our hospital were included in the study. All Doppler parameters of the celiac artery and SMA (peak systolic velocity (PSV); pulsatility index (PI); resistance index (RI); systolic/diastolic ratio (SD); time average maximum velocity (TAMAX)) were obtained by ultrasonography before and 1â¯h after OGTT. RESULTS: The mean PSV value of the celiac artery decreased statistically significantly after OGTT (37.29 ± 11.96â¯cm/s; 29.51 ± 10.07â¯cm/s; p=0.002). While the mean of the PI was 2.09 ± 0.57 before the test, it was found to be 1.84 ± 0.64 after the test (p=0.027). Mean PSV (39.82 ± 13.07â¯cm/s; 35.19 ± 15.27â¯cm/s; p=0.104) and PI (2.21 ± 0.65; 2.11 ± 0.80; p=0.375) values of SMA were also found to be decreased without statistically significancy. CONCLUSIONS: The data obtained from our study reveals that the PSV and PI values of celiac artery and SMA slightly decrease after OGTT.
