Retroperitoneal tumors with vena caval extension: a multidisciplinary approach.

In cases of retroperitoneal tumor with extension to the inferior vena cava (IVC), complete resection improves survival, but may require cardiopulmonary bypass (CPB) and hypothermic circulatory arrest (HCA). Since 1985, eight patients at our institution have had complete resection of retroperitoneal tumors with IVC or right atrial involvement. Preoperative evaluation included intravenous pyelography, computed tomography of the chest and abdomen, renal arteriography, and venography or magnetic resonance imaging of the IVC. Operative technique was determined primarily by the extent of IVC or RA involvement and included combined median sternotomy and laparotomy, control of the intrapericardial IVC, and radical tumor resection. IVC tumor thrombectomy was done using either temporary vascular occlusion, CPB, or CPB with HCA. Complete resection for improved survival of retroperitoneal tumors with IVC extension is technically feasible with acceptable morbidity and mortality rates. A multidisciplinary approach allows optimal management of these extensive tumors.
