Abstract
This study evaluates the endometrial receptivity of obstetric anticardiolipin syndrome (OAPS) patients using various ultrasound indicators and the efficacy of low-dose aspirin (LDA) treatment. This retrospective study recruited patients from Shanghai Ren Ji Hospital, China from January 2022 to December 2023. Doppler parameters of the endometrium and uterine artery blood flow were recorded to assess the endometrial receptivity of OAPS patients compared with normal pregnant women and an other immune diseases group. The receiver operating characteristic curve was used to predict the risk of OAPS patients. Doppler parameters of OAPS patients were conducted repeatedly after a 2-month period of treatment with LDA. Compared with normal pregnant women, the OAPS group showed remarkably increased endometrial perfusion resistance (PI, RI, S/D) and uterine artery perfusion resistance (RI and S/D) (P < 0.001) and had good predictive values (area under the curve = 0.806, 0.976, 0.942, 0.902, and 0.901, respectively). The endometrial thickness of the OAPS group was much thinner than that of the normal group (P < 0.001). Uterine blood flow impedance PI showed no difference in both groups (P = 0.68). In comparison to other autoimmune diseases, the OAPS group also showed an increasing trend in the resistance of endometrium and uterine artery blood flow. After LDA treatment, there was an obvious improvement in the endometrial blood flow perfusion in the OAPS group (P < 0.01). Compared with the normal group and other autoimmune diseases, the resistance of endometrial and uterine artery blood flow in the OAPS group was increased significantly. The Doppler index showed the predictive value of OAPS, and it was confirmed that LDA could enhance blood perfusion among OAPS women.
