GARCIA ORTELLS, D. et al. Surgical stratification of renal carcinoma with extension into inferior vena cava. Actas Urol Esp [online]. 2005, vol.29, n.5, pp.448-456. ISSN 0210-4806.

Renal cell carcinoma with inferior vena cava thrombus is relatively uncommon and complicates radical nefrectomy. During the past twenty years our hospital have substantially contributed to the surgical stratification of renal cell carcinoma with extension into inferior vena cava through different techniques. The reason for this article is to discuss the more efficient and appropiate surgical technique for this pathology. We believe that the diagnosis of vena caval invasion and level of tumoral extension is based on radiological examinations and it is crucial for the success of the surgery. We consider that the use of vena caval filter applied preoperatively could prevent the risk of thromboembolism during and after the surgery. The use of prosthetic grafts is unusual, because the long standing obstruction caused by the tumor thrombus will develope extensive collateral circulation which works as a natural veno-venous bypass. Finally, we try to avoid the use of veno-venous and cardiopulmonar bypass with or without complete hypothermic circulatory arrest due to the high association with adverse outcomes and mortality.
