摘要
目的 评价彩色多普勒血流显像(CDFI)及脉冲多普勒(PD)检测恶性滋养细胞肿瘤的早期诊断疗效观察及判断疾病转归的应用价值。方法 应用CDFI及PD检测恶性滋养细胞肿瘤患者32例,并以正常妊娠20例作对照。结果 CDFI恶性滋养叶肿瘤表现为丰富而敏感的彩色血流,PD为低速的动静脉血流。正常妊娠为不甚敏感的点状或多条状的不规则血流,PD为单相或双相的低速动脉血流。阻力指数(RI)显著性差异(P<0.01)。结论 CDFI和PD检测可做为一种新的方法,不仅可对滋养叶细胞肿瘤作出早期诊断,亦可用于观察化疗效果,判断疾病的转归。
Objective To investigate the value of color doppler flow imaging (CDFI) and pulsed doppler ( PD) determinations in early diangosis, eveluation of therapeutic effects and prediction of prognosis of gestational trophoblastic diseases (GID). Methods CDFI and PD were performed in 32 cases of GTD and 20 normal pregant women as controls. Results The uterine layer in GTD showed abundant sensitive colored blood flow with CDFI and arteriovenous blood flow with PD. While in control group showed nonsensitive point irregular blood flow with CDFI and monophasic or biphasic arterial blood flow of low speed with PD. There was a significant difference in resistant index (RI) (P<0.01). Conditions CDFI and PD as a new method for early diagnosis of GID can also be used to evaluate the chemotherapy eutio results as well as to determine the prognosis of the diseases.
