部分性葡萄胎彩色多普勒超声诊断价值研究

Study on the value of color Doppler ultrasound in diagnosis of partial hydatidiform mole

目的:比较彩色多普勒超声诊断与实验室病理检测结果,探讨彩色多普勒超声在部分性葡萄胎诊断中的应用价值。方法:随机选取40例超声诊断的部分性葡萄胎患者的临床资料其进行回顾性分析,观察病变的边界、内部回声,并运用彩色多普勒超声检查该病变边缘及内部的血流情况,应用频谱多普勒测量病变边缘和内部血流的RI值,并与病理结果比对。结果:40例经彩色多普勒超声诊断部分性葡萄胎患者有34例与病理结果相符合,诊断符合率为85%,6例误诊为不全流产;32例患者宫腔内回声不均呈蜂窝状改变,2例患者宫内见偏高回声不均区,仅6例患者表现为子宫内膜增厚。彩色多普勒血流显示34例病变内均未见明显血流信号,仅6例病变见较丰富的血流信号。结论:彩色多普勒超声检查有无创性、操作简便、可多次重复进行的优点,且诊断符合率高,在部分性葡萄胎诊断中具有重要作用,不典型者需要结合病理及实验室检查。

Objective： To compare the results of color Doppler ultrasonography and laboratory pathological examination,explore the application value of color Doppler ultrasound in diagnosis of partial hydatidiform mole. Methods： The clinical data of 40 patients diagnosed as partial hydatidiform mole by ultrasound were analyzed retrospectively; the boundary of lesions and internal echo were observed; color Doppler ultrasound was used to examine the boundary of lesions and internal blood flow; spectrum Doppler ultrasound was used to measure RI values of boundary and internal blood flow,then the results were compared with pathological results. Results： Among 40 patients,the results of color Doppler ultrasound and pathological examination in 34 patients were consistent,the coincidence rate was 85%,6 patients were misdiagnosed as incomplete abortion; intrauterine honeycomb intrauterine echo was found in 32 patients,high intrauterine echo uneven areas were found in 2 patients,only six patients were found with endometrial thickening. Color Doppler ultrasound showed unapparent blood flow signals in lesions of 34 patients,only 6 patients were found with abundant blood flow signals. Conclusion： Color Doppler ultrasound has the advantages of noninvasiveness,simplicity and high repeatability,and the diagnostic coincidence rate is high,which plays an important role in diagnosis of partial hydatidiform mole,the atypical patients require a combination of pathological examination and laboratory examination.
