Surgery of cavoatrial tumor thrombus in nephroblastoma: a report of the SIOP/GPOH study.
Resection of a Wilms tumor extending through the inferior vena cava into the right atrium represents a challenge to the pediatric surgeon. Exact preoperative diagnosis is essential to identify the tumor and its intravascular extension. To achieve a complete excision of the tumor cardiopulmonary bypass and hypothermia may be required. The feasibility of a complete resection is important as it guides subsequent therapy such as chemotherapy and radiation. ⋯ Our report suggests that Wilms tumor extending to the inferior vena cava and the right atrium is technical challenging, but with adequate preoperative diagnosis and a multidisciplinary surgical approach including cardiopulmonary bypass and hypothermia, the prognosis is favorable.
