Extension of renal cell carcinoma into the vena cava is found in 4 to 10 percent of patients. One key to successful surgical management is defining the superior extent of the thrombus. Currently, this is accomplished by using inferior venacavography. The limitations of this imaging technique include difficulty in defining the superior extent of the thrombus and determining the presence of hepatic vein involvement. We report our experience using magnetic resonance imaging (MRI) in 9 patients to stage the thrombus and to determine the operative approach. We believe that MRI supplants other imaging techniques for staging tumor thrombi in renal cell carcinoma.
4%至10%的肾细胞癌患者会出现癌组织延伸至腔静脉的情况。成功进行手术治疗的关键之一是明确血栓的上界范围。目前，这是通过下腔静脉造影来完成的。这种成像技术的局限性包括难以确定血栓的上界范围以及判断肝静脉是否受累。我们报告了对9例患者使用磁共振成像（MRI）来对血栓进行分期并确定手术入路的经验。我们认为，在对肾细胞癌的肿瘤血栓进行分期方面，MRI可取代其他成像技术。
