Abstract:	Uterine artery Doppler flow studies during the 11th and 14th 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 118 patients examined in our clinic, with pregnancies ranging from 11 weeks + 0 days to 13 weeks + 6 days. There were 59 patients from 11 weeks + 0 days to 11 weeks + 6 days (50%), 23 from 12 weeks + 0 days to 12 weeks + 6 days (19.49%), and 36 from 13 weeks + 0 days to 13 weeks + 6 days (30.51%). The values of the Doppler indices were: PI 1.69±0.75, 1.79± 0.78, 1.57±0.68, and 1.61±0.75and RI 0.72±0.14, 0.73±0.14, 0.70±0.13, and 0.71±0.14 for the entire group and for the three intervals respectively. There were 42 (35.59%), 25 (21.19%), and 51 (43.22%) patients with bilateral, unilateral and absent uterine artery notching, respectively. The Doppler indices for the three aforementioned groups were: 2.11±0.74.79, 1.68±0.73, and 1.35±0.59 for the PI and 0.78±0.11, 0.72±0.13, and 0.67±0.14for the RI, respectively. The mean uterine artery PI and RI vary from 11 weeks + 0 days-11 weeks + 6 days to 13 weeks + 0 days-13 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.
