摘 要:术前 1 周对 75 例卵巢肿瘤患者(53 例良性肿瘤,22 例恶性肿瘤)行 C 超检查及肿瘤内血流检测,并与术后的组织病理学诊断对照。结果:53 例卵巢良性肿瘤中 21 例(3962% ),22 例卵巢恶性肿瘤中21 例(9545% ) C 超显示结构异常;良性肿瘤的血流高峰收缩速度( P S V)的平均值为 142±8.1cm /s,阻抗指数( R I)平均值为 0.478±0.119。恶性肿瘤 P S V 的平均值为 242±11.5cm /s, R I平均值为 0478±0.119。当以 P S V 16cm /s 作为区分卵巢良、恶性肿瘤界值时, P S V 诊断卵巢恶性肿瘤的敏感性率和特异性率分别为 9091% 和 9057% ;当用 R I072 作为区分卵巢良、恶性肿瘤的界值时, R I诊断卵巢恶性肿瘤的敏感性率和特异性率分别为 8636% 和 6981% ; C 超诊断恶性肿瘤的敏感性率和特异性率分别为 9545% 和7170% 。三者的敏感性率差异无显著性,而 P S V 诊断卵巢恶性肿瘤的特异性率明显高于 R I和 C 超检查者,具有显著差异性( P< 0.05)。提示用多普勒血流显像技术检测卵巢肿瘤内异常血流的 P S VSeventy five cases of ovarian neoplasm (53 benign cases, 22 malignant cases) were detected for intraumor blood flow velocity with C mode ultrasound and Doppler flow imaging technique and contrasted to histopathological diagnosis. 21 cases of benign neoplasm (21/53,39.62%) and 21 maligant neoplasm (21/22, 95.45%) had adnormal morphologic fetures suggesting malignang abnormal morphologic fetures. In benign neoplasm the average value of peak systolic velocity (PSV) was detected 14.2±8.1cm/s and the resistance index (RI) was 0.478±0.119. In malignant neoplasm ,the average value of PSV was 24.2±11.5cm/s and the RI was 0.478±0.119. When considering as the cutoff value of PSV 16cm/s and demarcative value RI 0.72 for differentiation of benign or malignant tumors, the sensitive and specifitive rates of PSV in detecting malignant neoplasm were 90.91% and 90.57%, respectively, and the sensitivie and specifitive rates of the RI in malignant tumors were 86.36% and 69.81%, respectively, and those using C mode ultrasound were 95.45% and 71.70%, respectively, There were no singnificant difference in sensitivity among PSV, RI and C ultrasound. Howerver, the specificity of the PSV was significity higher than that of RI and C ultrasound(P<0.05). The PSV obtainted from intratumor abnormal morphologic features with Doppler ultrasonograpy may be used to different malignant from benign ovarian tumors.
