The present report describes two cases of T1b (>4 cm) renal cell carcinoma (RCC) treated with superselective embolization and radiofrequency ablation in the setting of renal artery stenosis and abdominal aortic aneurysm, respectively. In the first case, a solitary functioning kidney was treated with stent placement immediately before RCC embolization. In the second case, a brachial artery approach was used for RCC embolization after a failed femoral approach secondary to an abdominal aortic aneurysm. These cases illustrate the utility of combination therapy for T1b RCC and emphasize the need for interventional radiologists and interventional oncologists to possess the requisite endovascular skills to manage anatomic challenges from coexisting arterial disease when performing image-guided tumor interventions.
本报告描述了两例T1b期（>4cm）肾细胞癌（RCC）的病例，分别在肾动脉狭窄和腹主动脉瘤的情况下接受了超选择性栓塞和射频消融治疗。在第一例中，在对肾细胞癌进行栓塞治疗前立即通过放置支架对一个孤立的功能肾进行了处理。在第二例中，由于腹主动脉瘤导致股动脉入路失败后，采用肱动脉入路进行肾细胞癌栓塞。这些病例说明了联合治疗对T1b期肾细胞癌的实用性，并强调介入放射科医生和介入肿瘤学家在进行影像引导下的肿瘤干预时，需要具备必要的血管内技能，以应对并存动脉疾病带来的解剖学挑战。
