卵巢肿瘤的彩色多普勒血流显像特点与血管形态学相关性的研究

The Study of Correlation between Color Doppler Flow Imaging in Ovarian Tumor Signals and Neovascular Morphologic Features

本文应用经腹彩色多普勒及病理学检查方法，研究了５７例卵巢肿瘤的血流显像特点及其与肿瘤血管形态学之间的关系。结果表明，形成卵巢恶性肿瘤高阻低速血流频谱的病理基础为肿瘤内存在：（１）腔大、壁薄、仅衬内皮细胞、管壁缺乏平滑肌层的窦状血管；（２）中膜平滑肌层分布极度不均血管以及与增大的管径相比，平滑肌层相对减少的血管。从而为临床使用彩色多普肋鉴别卵巢肿瘤的良恶性提供了血管病理学依据。

The correlation of color Doppler flow imaging overian tumor signals with neovascular morphology were studied by transabdominal color Dopplor flow imaging and pnthology in 57 patients with ovarian tumors. The reaults showed that: the pathologic bases that give rise to blood flow spectra pattern of ovarian malignancies which had less impedance and high evlocity were:(1) very large,thin wall vascular spaces lined by endothlium and no evidence of muscular element in the wall.(2)deficient. development of muscular elements in the wall, or tumor vessels having a relative paucity of smooth muscle in the walls in comparsion with to their caliber.The study provided pathologic bases for the clinic in differentiating the malignancies from benigns.
