Removal of renal cell carcinoma (RCC) extended into the inferior vena cava (IVC) can be a difficult operation. Between 1941 and 1989, 110 RCC patients were treated with radical operation and examined for tumor thrombus histopathologically. Twenty nine (26.3%) patients had invasion into the returning vein of tumor (Stage Vla), 12 (10.9%) in renal vein (stage Vlb) and the remaining 4 (3.6%) into IVC (stage V2). In one patient who had surgery under extracorporeal circulation, a thrombus was extended into the right atrium. In the remaining three patients, the RCC was confined to a small portion of the IVC and operated by caval sleeve resection. Radical operation in such patients free of any distant metastasis, may raise the survival rate.
切除延伸至下腔静脉（IVC）的肾细胞癌（RCC）可能是一项困难的手术。1941年至1989年间，110例RCC患者接受了根治性手术，并对肿瘤血栓进行了组织病理学检查。29例（26.3%）患者肿瘤侵犯肾静脉（Ⅵa期），12例（10.9%）侵犯肾静脉（Ⅵb期），其余4例（3.6%）侵犯下腔静脉（Ⅴ2期）。1例患者在体外循环下进行手术，血栓延伸至右心房。其余3例患者，RCC局限于下腔静脉的一小部分，采用腔静脉袖状切除术进行手术。对于此类无远处转移的患者进行根治性手术，可能会提高生存率。
