Abstract:	Uterine artery Doppler flow studies during the 21st and 24th weeks of pregnancy are important in the prediction of preeclampsia and IUGR in pregnant women and also in the prevention thereof. Our study of the Doppler flow indices of the uterine arteries involves 59 patients examined in our clinic, with pregnancies ranging from 21 weeks + 0 days to 23 weeks + 6 days. There were 17 patients from 21 weeks + 0 days to 21 weeks + 6 days (28.82%), 23 from 22 weeks + 0 days to 22 weeks + 6 days (38.98%), and 19 from 23 weeks + 0 days to 23 weeks + 6 days (32.20%). The values of the Doppler indices were: PI 1.06±0.40, 1.00± 0.33, 1.07±0.45, and 1.11±0.38 and RI 0.58±0.11, 0.57±0.10, 0.58±0.12, and 0.59±0.10 for the entire group and for the three intervals respectively. There were 6 (10.17%), 9 (15.25%), and 44 (74.58%) patients with bilateral, unilateral and absent uterine artery notching, respectively. The Doppler indices for the three aforementioned groups were: 1.58±0.42, 1.29±0.52, and 0.95±0.28 for the PI and 0.72±0.10, 0.63±0.12, and 0.55±0.09for the RI, respectively. The mean uterine artery PI and RI vary from 21 weeks + 0 days-21 weeks + 6 days to 23 weeks + 0 days-23 weeks + 6 days. They also decrease from pregnant patients with bilateral uterine artery notching to those without notching. Our results are similar to those in literature.
