目的探讨早期异位妊娠患者临床应用经阴道彩色多普勒超声实施诊断的效果。方法 72例早期异位妊娠患者,将其设为观察组(C1组);同期宫内妊娠患者80例,将其设为对照组(C2组);两组均给予经阴道彩色多普勒超声检查,针对C1组与C2组患者的子宫内膜厚度以及血流参数进行观察,将最终的检测结果同患者的妊娠结果实施对比。结果在子宫内膜厚度方面,C2组患者厚于C1组患者(P<0.05);在C2组患者中,子宫动脉最终显示螺旋动脉的患者58例,临床显示率为72.50%;C1组患者中,子宫内膜中发现存在螺旋动脉血流信号的患者4例,临床显示率为5.56%,在螺旋动脉显示率方面,C1组小于C2组(P<0.05)。结论针对早期异位妊娠患者,选择经阴道彩色多普勒超声的方法实施临床诊断,通过对患者子宫内膜螺旋动脉显示率进行检测,最终能够有效将临床疾病的诊断率提高。 Objective To investigate the clinical application of transvaginal color Doppler ultrasound in the diagnosis of early ectopic pregnancy. Methods Seventy-two patients with early ectopic pregnancy were enrolled as observation group (group C1); 80 women with intrauterine pregnancy in the same period were enrolled as control group (C2 group); both groups were given transvaginal color Doppler ultrasonography The endometrial thickness and blood flow parameters of C1 and C2 patients were examined and the final test results were compared with those of the patients. Results In endometrial thickness, patients in C2 group were thicker than those in C1 group (P <0.05). In C2 group, 58 patients showed spiral artery in terminal uterine artery, the clinical manifestation rate was 72.50%. In C1 group In the endometrium, there were 4 patients with helical arterial blood flow signal, the clinical manifestation rate was 5.56%. In the spiral artery display rate, C1 group was smaller than C2 group (P <0.05). Conclusion For the patients with early ectopic pregnancy, the method of transvaginal color Doppler ultrasonography is selected for clinical diagnosis. The detection rate of endometrial spiral arteries in patients with endometriosis can finally be used to effectively improve the diagnosis rate of clinical diseases.
