Inferior venacavography was used for revealing enlarged retro- or paracaval lymph nodes, some of which are not visualized by lymphography as they lay above L 2. As criteria for involvement of lymph nodes the dislocation or narrowing of the vena cava and the reflux of contrast medium in the lumbar veins were studied. Venacavography was carried out in 48 consecutive patients with lymphomas: 23 Hodgkin's disease and 25 non-Hodgkin's lymphoma. Signs of enlargement of paracaval lymph nodes were seen in 52% of patients with Hodgkin's disease and in 80% of the cases of non-Hodgkin's lymphoma. A fairly good agreement was found to between lymphograms and cavograms. Cavography proved to be an easy, inexpensive and minimally invasive technique that can be repeated several times without inconveniencing the patients too much, thus enabling restaging of patients after therapy; moreover, it produced fairly good urograms as the contrast medium is promptly eliminated through the kidney, thus eliminating the need for intravenous pyelography.
下腔静脉造影用于显示腔后或腔旁肿大的淋巴结，其中一些位于L2水平以上，淋巴造影无法显示。以腔静脉移位或变窄以及腰静脉内造影剂反流作为淋巴结受累的标准进行研究。对48例连续的淋巴瘤患者进行了下腔静脉造影：23例霍奇金病和25例非霍奇金淋巴瘤。在52%的霍奇金病患者和80%的非霍奇金淋巴瘤病例中可见腔旁淋巴结肿大的迹象。发现淋巴造影和腔静脉造影之间有相当好的一致性。腔静脉造影被证明是一种简单、廉价且微创的技术，可以多次重复进行，而不会给患者带来太大不便，从而能够在治疗后对患者进行重新分期；此外，由于造影剂可迅速通过肾脏排出，因此它能产生相当好的尿路造影图像，从而无需进行静脉肾盂造影。
