Management of nephroblastoma with intracardiac extension: three case reports and review of the literature.
A single institution's experience of three patients with nephroblastoma extending via the inferior vena cava to the right heart is described. The case reports and the pertinent literature illustrate that preoperative failure to detect the intracardial extension increases the risk of right outflow obstruction and pulmonary embolism during or after surgery. Simultaneous thoraco-abdominal surgery with total circulatory arrest is advocated to remove the cardiac and caval tumor together with the primary tumor in order to prevent sudden hemodynamic and embolic complications. Noninvasive diagnostic methods usually suffice to detect this rare complication of nephroblastoma and to plan an interdisciplinary surgical procedure. The presence of this complication should not worsen the stage- and histology-related prognosis of the patient.
