目的 探讨肾癌下腔静脉癌栓的诊断和手术治疗。方法 分析我院１９９７ 年１ 月～１９９８ 年５ 月收治的肾癌伴下腔静脉癌栓病人５ 例。对Ⅲ型癌栓的４ 例采用深低温停循环下腔静脉切开取栓术；对Ⅰ型癌栓的１ 例行部分阻断下腔静脉取栓。结果 本组５ 例均经病理证实，且术后随访半年至２ 年，均存活。结论 对于没有局部淋巴结侵犯或远处转移的肾癌病人，根治性手术是最好的治疗方式。
Objective To investigate the diagnosis and surgical treatment of carcinoma of the inferior vena cava in renal cell carcinoma. Methods Five cases of renal cancer with IVC tumor thrombus admitted from January 1997 to May 1998 in our hospital were analyzed. Four cases of type Ⅲ tumor thrombus were treated by deep hypothermic circulatory invagination of inferior vena cava and thrombectomy. One case of type Ⅰ tumor thrombectomy was blocked by inferior vena cava. Results The group of 5 cases were confirmed by pathology, and follow-up for 6 months to 2 years, all survived. Conclusions Radical surgery is the best treatment for patients with renal cell carcinoma without local lymph node invasion or distant metastasis.
