目的 探讨输卵管动脉阻力指数在异位妊娠早期诊断中的临床价值。方法 将我院自2017年3月到2019年4月间收治确诊为输卵管异位妊娠患者76例作为研究组，随机选取同期入院检查各项指标正常的宫内早孕者78例作为对照组，均使用彩色多普勒超声诊断仪检查，对比观察两组对象输卵管动脉阻力指数存在的差异。结果 常规超声检查研究组患者的子宫内膜厚度明显薄于对照组（P＜0.05），其异位妊娠部位在输卵管壶腹部、间质部和壶腹部近峡部分别有64例、9例、3例；研究组有6例（7.89%）显示出子宫螺旋动脉，明显低于对照组57例（73.08%），研究组子宫螺旋动脉阻力指数明显高于对照组（P＜0.05）；研究组子宫动脉搏动指数和阻力指数均明显小于对照组，而输卵管动脉搏动指数和阻力指数均明显大于对照组（P＜0.05）；研究组患侧输卵管动脉阻力指数水平明显高于健侧（P＜0.05）。结论 输卵管异位妊娠患者经阴道彩色多普勒

Objective To explore the clinical value of oviduct artery resistance index in the early diagnosis of ectopic pregnancy. Methods From March 2017 to April 2019, 76 cases of ectopic pregnancy of fallopian tube were treated in our hospital as the study group, and 78 cases of early pregnancy in utero with normal indexes were randomly selected as the control group, all of them were examined by color Doppler ultrasound, and the difference of resistance index of fallopian tube artery between the two groups was compared. Results The thickness of endometrium in the study group was significantly thinner than that in the control group (P < 0.05). There were 64 cases, 9 cases and 3 cases of ectopic pregnancy in tubal ampulla, interstitial part and proximal isthmus of ampulla; 6 cases (7.89%) in the study group showed uterine spiral artery, which was significantly lower than 57 cases (73.08%) in the control group, and the resistance index of uterine spiral artery in the study group was significantly higher than that in the control group, with statistically significant difference (P < 0.05). The pulsation index and resistance index of fallopian tube artery were significantly higher than those of the control group (P < 0.05). The resistance index of the affected side was significantly higher than that of the healthy side (P < 0.05).Conclusion The information of endometrium, uterine spiral artery, oviduct artery blood flow pulsation index and resistance index are very important for the accurate diagnosis of the disease, which can be widely used in the clinic.
