经阴道彩色多普勒超声检测52例卵巢肿瘤内异常血流信号对卵巢肿瘤的性质预测

52 Cases Abnormal Blood Stream Signalof Ovary Tumor by TVS-CD,then to Forecast the Tumor's Type

目的:评价经阴道彩色多普勒超声(TVS- CD)检测卵巢肿瘤的异常血流信号对卵巢肿瘤的定性诊断。方法:对5 2例卵巢肿瘤经阴道彩色多普勒超声检测,记录其收缩期峰值流速(PSV)、阻抗指数(RI)。结果:5 2例卵巢肿瘤中,良性4 0例,恶性12例(均经手术后病检证实)。在4 0例卵巢良性肿瘤中,检测到血流的PSV平均为(15 .12±0 .91) cm/ s,RI平均为0 .5 2±0 .14 ;12例恶性肿瘤中,PSV为(2 5 .2 1±12 .5 3) cm/ s,RI为0 .4 4±0 .12 ;当以PSV =16cm/ s,RI=0 .4为卵巢良、恶性肿瘤的界值时,其良、恶性肿瘤预测准确率分别为87.5 0 % ,91.6 7%。结论:经阴道彩色多普勒超声检测卵巢肿瘤内异常血流的PSV,RI,对卵巢肿瘤性质的预测具有一定的临床意义。

Objective Qualitative diagnosis of ova ri an tumors by examination of intratumor blood flow with TVS-CD.Methods We used TVS-CD to check 52 patients who got ovary tumor and recorded the PSV and RI.Results Among the 52 ovary tumors,40 of them were carci noid,12 of them were malignant(they have treated by operation and affirmed by pa thology).In the 40 carcinoid tumors,the mean PSV were (15.12±0.91)cm/s and mean RI were 0.52±0.14;In the 12 malignanttumors,the mean PSV were (25.21±12.53)c m/s and mean RI were 0.44±0.12.If we use PSV=16 cm/s and RI=0.4 as boundary bet ween carcinoid and malignant ovary tumor,the veracity rate were 87.5 %,91.67 %. Conclusion detect the abnormal blood stream signal of ovary tumor by TVS-CD and measure it's PSV and RI are helpful for us to forecast the ovary tumor's type.
