彩色多普勒血流对不典型葡萄胎诊断价值 　　[摘要] 目的 探讨彩色多普勒血流显像对不典型葡萄胎的诊断价值。方法 回顾分析经彩色多普勒血流显像检查后经手术病理证实的30例不典型葡萄胎的声像图及彩色多普勒血流特征。结果 30例不典型葡萄胎声像图无特异性，其中13例声像图类似不全流产，17例声像图类似宫腔积血。彩色多普勒血流显像：30例不典型葡萄胎中25例宫腔内团块样病变(类似不全流产10例、类似宫腔积血块15例)及宫壁可见较丰富的血流信号，均呈低阻动脉血流信号，阻力指数(RI)：0.45±0.08。结论 二维超声对不典型葡萄胎无特异性，彩色多普勒血流显像对不典型葡萄胎宫腔团块内可记录到高速低阻血流信号；因此彩色多普勒血流显像对不典型葡萄胎诊断具有重要的临床价值。 　　[关键词] 彩色多普勒血流显像； 不典型葡萄胎； 阻力指数 　　[中图分类号] R445[文献标识码] B[文章编号] 1005-0515（2011）-07-305-01 　　Significance of Color Doppler Flow Imaging for Diagnosing Atypical Hydatidiform Mole 　　Liu Xiaofei 　　(Department of Ultrasound, Traditional Chinese Medical HospitalYulin Shanxi719000China) 　　[Abstract] Objective To evaluate the clinical value of color Doppler flow imaging (CDFI) for diagnosing atypical hydatidiform mole. Methods Atypical hydatidiform mole affirmed by post- operative pathology in 30 cases were involved retrospectiveIy．Blood flow signals, spectral features, 2-Dimages of the hydatidiform mole were studied in the 30 cases. Results 2-D images of the 30 cases did not feature．In the 30 eases，2-D images of 13 cases were similar incomlete abortion， but 17 cases were similar uterne canal blood masses，color flow signals in uterne canal mas ses could be detected in 25 patients of 30 cases，no color Doppler blood flow could be found in 5 cases．The direct man ifestaon of Doppler spectrum was high velocity flow with low resistance. Resistance index (RI) was 0.45±0.08. Conclusions CDFI is a valuable means for diagnosing atypical hydatidiform ulole． 　　[Keywords] Color Doppler flow imaging; Atypical hydatidiform mole; Resistance index 　　葡萄胎是常见的妊娠早期疾病，对于典型者容易诊断，由于不典型葡萄胎属于葡萄胎的早期病变，声像图不典型且与典型声像图完全不同，类似于不全流产及宫腔积血块，故容易误诊为??全流产及宫腔积血等其他妇科疾病，为了提高早期诊断葡萄胎的准确率减少误诊率。现将我室2005年～2010年经彩色多普勒血流检查后经手术病理证实的30例不典型葡萄胎的声像罔特征进行回顾性分析，现报道如下。 　　1 资料与方法 　　1.1 研究对象 30例患者均来自我院门诊及住院患者，年龄20～35岁之间，临床以下腹痛、阴道不规则出血、早孕、先兆流产、不全流产等就诊。 　　1.2 使用仪器 ALOKAα-5，ALOKAα-10，ALOKA-5000彩色多普勒超声诊断仪，凸阵探头，频率3～5 MHz。 　　1.3 检查方法 适当充盈膀胱，患者平卧位常规全面扫查盆腔结构重点观察子宫及附件，发现宫腔病变时观察病变大小、回声与宫壁的关系并使用彩色多普勒血流(
