目的 探究子宫血流动力学指标指导药物流产少量宫腔残留物期待治疗的临床价值。方法 自2025年4月起，本院妇产科开始收集进行药物流产的病例资料，至2026年4月止共纳入50例，2周后均出现阴道持续性出血、腹痛等症状。通过阴道彩色多普勒超声检测患者子宫血流动力学指标水平，分析期待治疗的适用性。结果 通过阴道彩色多普勒超声检测发现，非宫内残留物患者血流搏动指数、阻力指数均较宫内残留物患者明显偏高（P<0.05）。无滋养血流者进行期待治疗成功率85.19%较滋养血流者的0%明显偏高（P<0.05）。通过logistic回归模型分析发现，滋养血流信号是导致期待治疗转归清宫术的重要影响因素。结论 彩色多普勒超声检测搏动指数、阻力指数等子宫血流动力学指标，可判断残留物的血流情况，并根据滋养血流信号判断期待治疗的适用性及有效性，子宫血流动力学指标对临床治疗具有重要的指导意义。
Objective To explore the clinical value of uterine hemodynamic indicators in guiding the treatment of small residual uterine cavity in medical abortion. Methods Starting from April 2025, the Obstetrics and Gynecology Department of our hospital began collecting case data on medical abortion. By April 2026, a total of 50 cases were included, all of whom experienced persistent vaginal bleeding, abdominal pain, and other symptoms 2 weeks later. By using vaginal color Doppler ultrasound to detect the level of uterine hemodynamic indicators in patients, analyze the applicability of expected treatment. Results Through vaginal color Doppler ultrasound detection, it was found that the blood flow pulsatility index and resistance index of non intrauterine residue patients were significantly higher than those of intrauterine residue patients (P<0.05). The success rate of expectant treatment for patients without nourishing blood flow was significantly higher at 85.19% compared to 0% for those with nourishing blood flow (P<0.05). Through logistic regression model analysis, it was found that nourishing blood flow signals are an important influencing factor leading to the expected treatment outcome of curettage surgery. Conclusion Color Doppler ultrasound can detect uterine hemodynamic indicators such as pulsatility index and resistance index, which can determine the residual blood flow situation and judge the applicability and effectiveness of expected treatment based on nourishing blood flow signals. Uterine hemodynamic indicators have important guiding significance for clinical treatment.
