Abstract：Objective To explore the evaluation value of transvaginal ultrasound in measuring endometrial thickness and blood flow parameters for endometrial receptivity(ER)in infertile patients with endometriosis(EMs).Method 30 in-fertile patients with EMs admitted to Foshan Fosun Chancheng Hospital from March 2023 to March 2024 were selected as the observation group;Additionally,30 women of childbearing age who underwent normal physical examinations during the same period were selected as the control group.All selected individuals underwent transvaginal ultrasound examination.Compare the endometrial thickness,endometrial pulsatility index(PI),S/D,and resistance index(RI)between two groups;Comparing the blood flow distribution types of two groups of endometrium and subendometrium,classification criteria:during the exam-ination,blood flow signals were observed in both endometrium and subendometrium,indicating type Ⅰ;only blood flow signals were observed in subendometrium,indicating type Ⅱ;and no obvious blood flow signals were observed in both endometrium and subendometrium,indicating type Ⅲ.Using logistic regression analysis to investigate the effect of transvaginal ultrasound detec-tion of blood flow parameters on ER deficiency.Result The difference in endometrial thickness between the two groups was not statistically significant(P＞0.05);The S/D value,PI,and RI of the observation group were(4.26±0.41),(1.92±0.31),and(0.88±0.06),all higher than those of the control group(3.22±0.34),(1.34±0.22),and(0.71±0.04),with statistical significance(P＜0.05).The proportion of type Ⅰ blood flow distribution in the observation group was 23.33％(7/30),which was lower than the control group's 70.00％(21/30),and the dif-ference was statistically significant(P＜0.05).Single factor analysis showed that the proportion of PI ≥ 1.6,S/D ≥ 3.6,and RI ≥ 0.72 in the observation group was higher than that in the control group(P＜0.05).According to logistic regression analysis,PI ≥ 1.6,S/D ≥ 3.6.and RI ≥ 0.72 are independent risk factors for ER reduction in infertile patients with EMs(P＜0.05,and OR≥1).Conclusion The hemodynamic status of uterine arteries can be affected by EMs,resulting in abnormally high levels of various blood flow parameter indicators,significantly increased blood flow resistance,affecting blood flow supply,and even causing blood flow supply disorders,thereby reducing ER.Transvaginal ultrasound can be used to monitor endometrial thickness and blood flow parameters for endometriosis infertility,fully understand the condition of the endometrium,accurately evaluate ER,and guide clinical treatment.
