为探讨经阴道彩色多普勒超声（ＴＶＣＤ）对侵蚀性葡萄胎的早期诊断，对１９例侵蚀性葡萄胎行ＴＶＣＤ血流检测，以９１例正常早孕、３５例正常非孕子宫、１３例良性葡萄胎作为对照组。结果：侵蚀性葡萄胎肌壁血流丰富，子宫动脉和螺旋动脉ＰＳ值明显增高（Ｐ＜０．００５），ＲＩ、ＰＩ值明显降低（Ｐ＜０．００５）。以肌壁血窦＞５ｍｍ作为侵蚀性葡萄胎的诊断标准，其敏感性９５％，特异性１００％。表明ＴＶＣＤ是检测侵蚀性葡萄胎的有效方法，血流动力学参数和肌壁血窦对早期诊断具有重要的价值。
To investigate the early diagnosis of invasive hydatidiform mole by transvaginal color Doppler ultrasound (TVCD), TVCD blood flow was measured in 19 cases of invasive hydatidiform mole with 91 normal early pregnancies, 35 normal non-pregnant uterus and 13 benign Hydatidiform mole as a control group. Results: The blood flow in the corpus callosum was rich, the PS value of uterine artery and spiral artery were significantly increased (P <0.005), RI and PI were significantly decreased (P <0.005). The muscle wall sinus> 5mm as the diagnostic criteria for invasive hydatidiform mole, the sensitivity of 95%, 100% specificity. It is indicated that TVCD is an effective method to detect invasive hydatidiform mole. Hemodynamic parameters and muscular sinusoids are of great value in the early diagnosis.
