肾细胞癌无知觉地侵入下腔静脉内,常常是迅速死亡的先兆。虽然,这个问题有许多个案报告,然而对于这类病变以解剖学为基础的统一的手术途径从未确立。为了弄清有关腔静脉内肾细胞癌许多手术上的问题,作者回顾了自己及他人的经验,详细地研究了肾静脉栓塞之后侧枝循环的解剖类型。结合已有的解剖学知识,下腔静脉栓塞患者的下腔静脉造影以及作者自己手术和尸体解剖所获得的资料,作者提出对血管内肿瘤分类的系统方法,据此新的分类法,可在术前制定出每一种类型的血管内肾细胞癌的合理的手术途径。临床资料自1970年5月至1977年7月共收治72例肾细胞癌患者,其中有15例侵及血管内。4例肿瘤延伸入腔静脉内。1977年7月以后又遇到2例恶性的腔静脉血栓形成的病例。共6例。结果临床表现:男性4例,女性2例,最常见的症状 Renal cell carcinoma invades the inferior vena cava insidiously and is often a precursor to rapid death. Although many cases have been reported on this issue, an anatomically-based uniform surgical approach has never been established. In order to clarify many surgical problems related to renal cell carcinoma in the vena cava, the authors reviewed the experience of themselves and others and studied in detail the anatomical types of collateral circulation after renal vein thrombosis. Combining the existing anatomy knowledge, inferior vena cava angiography in patients with inferior vena cava thrombosis, and the data obtained by the author’s own surgery and autopsy, the authors propose a systematic method for the classification of intravascular tumors. According to this new classification method, Preoperatively, a reasonable surgical route for each type of intravascular renal cell carcinoma was developed. Clinical data From July 1970 to July 1977, a total of 72 patients with renal cell carcinoma were treated, of which 15 were invading the blood vessels. Four tumors extended into the vena cava. In July 1977, two cases of malignant vena cava thrombosis were encountered. A total of 6 cases. Results Clinical manifestations: 4 males and 2 females, the most common symptoms
