Patients with renal cell carcinoma (RCC) frequently have tumor thrombus of the renal vein or inferior vena cava (IVC). During radical nephrectomy, the tumor thrombus may become dislocated due to manipulation of the IVC during tumor isolation, which may result in pulmonary embolism. Placement of vena cava filters at the proximal end of the tumor thrombus have successfully prevented pulmonary embolism. We herein report the use of the Tempofilter II, a temporary filter for the prevention of pulmonary embolism.
From 2006 to 2008, seven patients with RCC and level II or III IVC tumor thrombus received radical nephrectomy with resection of the tumor thrombus. The Tempofilter II was inserted before the operation and removed postoperatively.
The resection was successful in all seven cases. No complications, pulmonary embolism, or perioperative death occurred. No metastasis or tumor recurrence was detected during the follow-up period.
The Tempofilter II is effective in preventing pulmonary embolism during resection of RCC and IVC thrombi. The filter is simple to insert and removal does not required imaging.
肾细胞癌（RCC）患者常伴有肾静脉或下腔静脉（IVC）肿瘤血栓形成。在根治性肾切除术中，肿瘤血栓可能因分离肿瘤时对下腔静脉的操作而发生移位，进而导致肺栓塞。在肿瘤血栓近端放置腔静脉滤器已成功预防了肺栓塞。我们在此报告使用Tempofilter II（一种用于预防肺栓塞的临时滤器）的情况。
2006年至2008年，7例患有RCC且下腔静脉肿瘤血栓为II级或III级的患者接受了根治性肾切除术及肿瘤血栓切除术。术前插入Tempofilter II，术后取出。
7例手术均成功。未发生并发症、肺栓塞或围手术期死亡。随访期间未检测到转移或肿瘤复发。
Tempofilter II在预防RCC和IVC血栓切除术中的肺栓塞方面有效。该滤器插入简单，取出无需影像学检查。
