Methods: 94 patients with URSA from September 2021 to August 2023 were selected as the URSA group, and 110 normal pregnant women who underwent prenatal examination were selected as the control group. The URSA patients were followed up until 28 weeks of gestation and divided into the normal pregnancy group (n = 25) and the abortion group (n = 69) according to the pregnancy outcome. The uterine artery blood flow parameters and platelet aggregation rate were compared between the two groups. The predictive value of the uterine artery flow parameters and platelet aggregation rate for the pregnancy outcomes of URSA patients was evaluated by ROC. Binary Logistic stepwise regression was employed to explore the influencing factors of the pregnancy outcomes of URSA patients. Results: The indexes of the pulse index (PI), the arterial flow resistance index (RI), the systolic/diastolic blood flow velocity ratio (S/D), and the platelet aggregation rate in the URSA group were higher than those in the control group (P P P < 0.05). The ROC curve demonstrated that the area under the curve (AUC) (95% CI) of the uterine artery flow parameters, the platelet aggregation rate, and their combined prediction of the pregnancy outcomes of URSA patients were 0.858 (0.807~0.910), 0.764 (0.753~0.816), and 0.903 (0.852~0.955), respectively. Conclusion: The level of the uterine artery blood flow parameters and the increase of the platelet aggregation rate are closely associated with the pregnancy outcome of URSA patients, and the combined value of the two is highly significant in predicting the pregnancy outcome of URSA patients.展开更多
