Léiomyosarcome du segment moyen de la veine cave inférieure : problèmes tactiques soulevés par la revascularisation cave et rénale

We emphasize the importance of restoring caval outflow which provides effective results when used with a ring-reinforced polytetrafluoroethylene (PTFE) prosthesis. Furthermore, the importance of restoring right renal outflow is highlighted because ligature of the renal vein can lead to renal ischemia and nephrectomy which should only be performed in specific cases. The tactical problems of renal and caval revascularisation, including the place of prosthetic replacement, are discussed. (J Mal Vasc 2006; 31: 79-84).
