彩色多普勒超声监测子宫动脉血流对诊断绝经后阴道出血的临床意义

目的探究彩色多普勒超声监测子宫动脉血流对诊断绝经后阴道出血的临床意义。方法选取2018年3月至2019年3月本院收治的62例疑似绝经后阴道出血患者为观察组,另选取同期62名绝经后健康体检女性为对照组,均行常规超声检查、彩色多普勒超声监测子宫动脉血流。比较两组舒张期末流速(EDV)、收缩期峰值流速(PSV)、阻力指数(RI)、搏动指数(PI),记录观察组不同病变类型子宫内膜厚度、动脉血流。结果观察组EDV、PSV高于对照组,RI、PI低于对照组(P<0.05);观察组子宫内膜癌的内膜厚度较高,萎缩性内膜厚度较低,内膜癌的RI值较低,未能显示萎缩性内膜的RI值;彩色多普勒血流成像诊断绝经后阴道出血的灵敏度96.08%(49/51)、准确率91.94%(57/62)高于常规超声的80.39%(41/51)、77.42%(48/62),差异具有统计学意义(P<0.05)。结论彩色多普勒超声监测子宫动脉血流可有效诊断绝经后阴道出血,除常规观察子宫内膜形态、厚度外,通过分析子宫内膜血流频谱,反映不同病变类型的子宫内膜厚度及动脉血流差异,有助于疾病诊断。

The clinical significance of color Doppler ultrasound monitoring uterine artery blood flow in diagnosing postmenopausal vaginal bleeding

Objective To explore the clinical significance of color Doppler ultrasound monitoring uterine artery blood flow in the diagnosis of postmenopausal vaginal bleeding.Methods A total of 62 patients with suspected postmenopausal vaginal bleeding admitted to our hospital from March 2018 to March 2019 were selected as the observation group.In addition,62 postmenopausal women with healthy physical examination during the same period were selected as the control group.Routine ultrasound and color Doppler ultrasound were performed to monitor the blood flow of the uterine artery.The end-diastolic velocity(EDV),peak systolic velocity(PSV),resistance index(RI),and pulsatility index(PI)were compared between the two groups,and the endometrial thickness and arterial blood flow of different lesion types in the observation group were recorded.Results The EDV and PSV of the observation group were higher than those of the control group,and the RI and PI were lower than those of the control group(P<0.05).In the observation group,the endometrial thickness of endometrial cancer was higher,the thickness of atrophic endometrial was lower,and the RI value of endometrial cancer was lower,which failed to show the RI value of atrophic endometrial.The sensitivity of color Doppler blood flow imaging in diagnosing postmenopausal vaginal bleeding was 96.08%(49/51),and the accuracy was 91.94%(57/62)which were higher than that of conventional ultrasound 80.39%(41/51)and 77.42%(48/62),the difference was statistically significant(P<0.05).Conclusion Color Doppler ultrasound monitoring uterine artery blood flow can effectively diagnose postmenopausal vaginal bleeding.In addition to the routine observation of the morphology and thickness of the endometrium,the analysis of the blood flow spectrum of the endometrium can reflect the difference in the thickness of the endometrium and the arterial blood flow of different disease types,which is helpful for disease diagnosis.
