Abstract:
Objective:To investigate the clinical value of micro-vascular flow(MV-flow)imaging in evaluating the difference of endometrial micro-flow vascularization index(ⅥMV)between recurrent spontaneous abortion and normal reproductive age women.Methods:From June 2022 to June 2023,87 patients with unexplained recurrent spontaneous abortion in West China Second University Hospital,Sichuan University were selected as the abortion group,including 51 patients with 2 miscarriages,26 patients with 3 miscarriages,and 10 patients with≥4 miscar-riages.In addition,90 normal women of childbearing age who did not have a history of miscarriage and visited our hospital during the same period were selected as the healthy group.Endometrial ⅥMV was measured by transvag-inal ultrasound using MV-flow imaging technology in mid-luteal phase of the two groups.The mean values of en-dometrial ⅥMV in 177 women was measured repeatedly within and between observers.The endometrial ⅥMVand clinical data were compared between the two groups.The differences of endometrial ⅥMV and clinical data in pa-tients with different miscarriage times in the abortion group were compared simultaneously.Results:There was no statistically significant difference in age,body mass index,follicle stimulating hormone and luteinizing hormone be-tween the healthy group and the abortion group(P＞0.05).The ⅥMV of endometrium in healthy group was higher than that in abortion group,and the difference was statistically significant(6.10％vs.3.70％,P＜0.05).In the abortion group,endometrial ⅥMV in patients with 2 miscarriages(5.30％)was higher than that in patients with 3(3.25％)miscarriages and≥ 4(3.30％)miscarriages,and the difference was statistically significant(P＜0.05).There was no statistically significant difference in endometrial ⅥMV between patients with 3 miscarriages and ≥4 miscarriages(P＞0.05).The intraobserver and interobserver correlation coefficients of endometrial ⅥMV were 0.978 and 0.945,respectively.Conclusions:MV-flow imaging technology can effectively evaluate the difference of endometrial ⅥMV between recurrent spontaneous abortion and normal childbearing age women,and endometri-al ⅥMV may decrease with the increase of miscarriage frequency.
