摘要
经阴道彩色多普勒超声探查对75例共97个卵巢肿块进行了研究。术后证实恶性肿瘤52个,良性肿瘤35个,炎性肿块和交界性肿瘤分别为7个和3个。结果提示:经阴道探查对卵巢肿块的形态学观察有很大帮助;恶性肿瘤侧子宫动脉血流阻力明显低于非肿瘤侧及其它组肿块侧;恶性肿瘤血流探查阳性率为100%,呈多处血流显示,阻力值明显低于其它肿块。以阻力指数(RI)<0.5、搏动指数(PI)<1.0为良、恶性肿瘤交界点,则诊断的敏感性、特异性及正确率分别是83.33%、78.95%和90.91%。因此认为经阴道彩色多昔勒超声探查对卵巢肿块的鉴别诊断有重要价值,并提出了易误诊的注意事项。
Seventy-five cases with 97 ovarian masses were studied by transvaginal color Doppler. 52 ma-lignant, 35 benign, 3 boundary and 7 inflammatory masses were proven by surgery and histopathology. The results showed that it was of great help to observe the structure of ovarian masses by transvaginal ultrasono-graphy; the resistance of uterine artery on the malignant masses side was significantly lower than that on the non-masses side of the same group and masses side of other groups'; the positive rate of blood flow signals at different vascular locations within malignant masses was 100%, its resistance was significantly lower than that of other masses'. If RI<0. 5 and PI<1. 0 were the boundary between malignant and benign masses, the sensitivity rate, specificity and accuracy rate of diagnosis were 83.33%, 78.95% and 90.91%, respectively. We consider it of great value to make differential diagnosis of ovarian masses by transvaginal color Doppler. In addition, the factors leading to erroneous diagnosis were discussed.
