肾癌并下腔静脉癌栓在临床较为少见,其发生率约为7％～9％,其中浸润性癌栓占下腔静脉癌栓12.9％～28.5％。我们近年对2例右肾癌并下腔静脉浸润性癌栓梗阻,行节段性腔静脉切除根治术,取得满意效果,报告如下。1 资料与方法1.1 临床资料:2例患者均为男性,分别为47岁、56岁,以无痛性肉眼血尿并一过性双下肢凹陷性水肿入院,经超声、CT及MRI检查确诊右肾癌伴下腔静脉癌栓完全性梗阻(肝下型),癌栓分别长3.5cm、
RCC and IVC tumor thrombus are rare in clinic, and the incidence rate is about 7% ~ 9%. Among them, invasive tumor thrombus accounts for 12.9% -28.5% of IVC tumor emboli. In recent years, we have 2 cases of right renal cell carcinoma and infiltration of inferior vena cava tumor embolism, segmental resection of the root canal surgery, and achieved satisfactory results, the report is as follows. 1 Materials and Methods 1.1 Clinical data: 2 patients were male, respectively, 47 years old, 56 years old, with painless gross hematuria and transient depression of lower extremity edema admission, ultrasound, CT and MRI examination confirmed the right kidney Cancer with inferior vena cava tumor thrombus complete obstruction (subhepatic type), tumor emboli were 3.5cm long,
