彩色多普勒超声诊断滋养细胞肿瘤盆腹腔转移灶

目的探讨滋养细胞肿瘤盆腹腔转移灶的彩色多普勒超声特征。方法对13例滋养细胞肿瘤患者（绒毛膜癌4例，侵蚀性葡萄胎9例）盆腹腔转移灶的彩色多普勒及频谱多普勒超声特征及其临床血清β-hCG检测情况进行回顾性分析。结果13冽滋养细胞肿瘤中4冽绒毛膜癌彩色多普勒超声显示盆腹腔转移灶（2例宫旁转移灶、1例结肠壁转移灶、1例宫旁血窦），其中3例伴血清β-hCG升高；9例葡萄胎清除术后1～3个月发生侵蚀性葡萄胎，彩色多普勒超声均显示子宫肌壁病变及盆腹腔转移灶（宫旁血窦3例、盆侧壁网状转移2例，实性病灶中宫旁转移1例、腹腔转移1例、右肾转移1例，结肠壁转移1例），9例均伴血清β-hCG升高。13例中绒毛膜癌或侵蚀性葡萄胎患者的盆腹腔转移灶与其子宫或卵巢病灶的声像图表现极其相似，以网状结构（3例）、血窦（4例）及实性转移灶（盆腹腔转移灶6例）为特征；彩色多普勒超声显示血流丰富，频谱阻力指数范围0．34±0．07，与侵蚀子宫肌壁病变一样呈高速低阻血流。12例盆腹腔转移灶经手术或化疗取得效果后均消失，1例侵蚀性葡萄胎化疗后右肾转移灶未完全消退。结论彩色多普勒超声检查对发现子宫以外的滋养细胞肿瘤盆、腹腔转移灶有重要作用。

Ultrasound and Doppler imaging in the diagnosis for metastasic lesion of trophoblastic tumor in abdominopelvic cavities

Objective To study characteristic of metastasic lesion of trophoblastic tumor in abdominopelvic cavities by color Doppler ultrasound.Methods Thirteen cases of trophoblastic tumors(4 cases of choriocarcinoma and 9 cases of invasive hydatidiform moles) were analysed by retrospective review.Clinical features,ultrasonographic findings,Doppler waveforms,and patient outcomes were followed.Results Of the 13 patients with trophoblastic tumors,4 had choriocarcinoma(1 cystic vascular space around the uterus,1 colonic...
