In seven out of 45 cases with malignant growths in kidneys and adrenal glands, sonography presented tumor-induced changes in the vena cava. The accuracy of this technique in detecting changes in the vena cava corresponds to that of cavography. Thus, it is no longer necessary to use cavography--except as a supplementary method mainly in cases where with sonography it is difficult to differentiate between an incomplete and a complete occlusion of the vena cava or between a cone-shaped invasion of the neoplastic thrombus into the inferior vena cava and an infiltration of the tumor into the wall of the vena cava.
在45例肾脏和肾上腺恶性肿瘤病例中，有7例超声检查显示肿瘤引起了腔静脉的改变。该技术检测腔静脉改变的准确性与腔静脉造影相当。因此，不再需要使用腔静脉造影——除非作为一种辅助方法，主要用于超声检查难以区分腔静脉不完全和完全闭塞，或难以区分肿瘤性血栓呈锥形侵入下腔静脉与肿瘤浸润腔静脉壁的情况。
