The objective of the study was assessment of the adnexal tumor vascularization with transvaginal color and pulsed Doppler sonography. Vessel location, its arrangement, and pulsed Doppler waveform characteristics were used to distinguish benign from malignant vascularity. The study was designed as a retrospective one in which sonographic and personal records of 254 women were investigated. The significance between ultrasonic results was analyzed by difference between group means and pooled estimate of variance. Results showed that peripheral and pericystical location with single vessel displayed and resistance index above 0.40 were highly associated with benign ovarian lesions. Blood vessels located in the centar, septum, and papillary projection of the tumor with diffuse dispersed vascular arrangement and resistance index below 0.41 were highly correlated with malignancy. There were no statistically significant differences in blood flow velocities observed at different vascular locations and vessel arrangement between benign and malignant ovarian masses. In conclusion, in addition to resistance index analysis of blood flow, vascular arrangement and location are important for accurate discrimination of benign from malignant ovarian lesions.
本研究的目的是通过经阴道彩色和脉冲多普勒超声评估附件肿瘤的血管形成情况。利用血管位置、其排列方式以及脉冲多普勒波形特征来区分良性和恶性血管。本研究设计为回顾性研究，调查了254名女性的超声检查和个人记录。通过组间均值差异和合并方差估计分析超声结果之间的显著性。结果显示，单支血管的周边和囊肿周围位置以及阻力指数高于0.40与良性卵巢病变高度相关。位于肿瘤中心、隔膜和乳头状突起的血管，血管呈弥漫性分散排列且阻力指数低于0.41与恶性肿瘤高度相关。在良性和恶性卵巢肿块的不同血管位置和血管排列处观察到的血流速度没有统计学上的显著差异。总之，除了血流阻力指数分析外，血管排列和位置对于准确区分良性和恶性卵巢病变很重要。
