Uterine artery Doppler flow studies during the 11th and 14th week of pregnancy are important in the prediction of preeclampsia and intrauterine growth restriction in pregnant women as well as in the prevention thereof.
Our study on Doppler flow indices of the uterine arteries involved 168 patients examined in our clinic, with pregnancies ranging from 11 weeks + 0 days to 13 weeks + 6 days.
There were 72 patients from 11 weeks + 0 days to 11 weeks + 6 days (42.86%), 43 from 12 weeks + 0 days to 12 weeks + 6 days (25.60%), and 53 from 13 weeks + 0 days to 13 weeks + 6 days (31.55%). The mean values of the Doppler indices were PI 1.75±0.79, 1.88± 0.81, 1.71±0.81, and 1.58±0.72 and RI 0.72±0.14, 0.75±0.14, 0.71±0.14, and 0.70±0.14 for the entire group and for the three intervals, respectively. There were 71 (42.26%), 33 (19.64%, with 18 cases or 54.55% on the right side), and 64 (38.10%) patients with bilateral, unilateral and absent uterine artery notching, respectively. The mean Doppler indices for the three aforementioned groups were 2.18±0.79, 1.63±0.72, and 1.33±0.57 for the PI, and 0.79±0.11, 0.71±0.14, and 0.66±0.14 for the RI, respectively. The indices for the 175 arteries with and 161 without notching, taken separately, in all patients, as well as for the uterine arteries with and without notching in patients with unilateral notching only were 2.16±0.76, 1.30±0.54, 2.08±0.66, and 1.17±0.43 for the PI, and 0.79±0.11, 0.65±0.14, 0.79±0.11, and 0.63±0.12 for the RI, respectively.
The mean uterine artery PI and RI decrease from 11 weeks + 0 days-11 weeks + 6 days to 13 weeks + 0 days-13 weeks + 6 days. They also decrease from patients with bilateral uterine artery notching to those without notching. The frequency of uterine artery notching decreases with increasing gestational age. Our results are similar to those in literature.
妊娠第11周和第14周期间的子宫动脉多普勒血流研究对于预测孕妇先兆子痫和胎儿宫内生长受限以及预防这些情况具有重要意义。
我们对子宫动脉多普勒血流指数的研究纳入了在我们诊所接受检查的168例患者，其孕周从11周0天至13周6天。
孕周为11周0天至11周6天的患者有72例（42.86%），12周0天至12周6天的有43例（25.60%），13周0天至13周6天的有53例（31.55%）。整个组以及三个时间段的多普勒指数平均值分别为：搏动指数（PI）1.75±0.79、1.88±0.81、1.71±0.81和1.58±0.72，阻力指数（RI）0.72±0.14、0.75±0.14、0.71±0.14和0.70±0.14。双侧、单侧子宫动脉切迹缺如的患者分别有71例（42.26%）、33例（19.64%，其中右侧18例或54.55%）和64例（38.10%）。上述三组的平均多普勒指数分别为：PI为2.18±0.79、1.63±0.72和1.33±0.57，RI为0.79±0.11、0.71±0.14和0.66±0.14。在所有患者中，分别对175条有切迹和161条无切迹的动脉进行分析，以及仅对单侧切迹患者中有切迹和无切迹的子宫动脉进行分析，结果显示PI分别为2.16±0.76、1.30±0.54、2.08±0.66和1.17±0.43，RI分别为0.79±0.11、0.65±0.14、0.79±0.11和0.63±0.12。
子宫动脉平均PI和RI从11周0天至11周6天到13周0天至13周6天呈下降趋势。从双侧子宫动脉有切迹的患者到无切迹的患者也呈下降趋势。子宫动脉切迹的频率随孕周增加而降低。我们的结果与文献报道相似。
