Suprahepatic Cava Thrombus Due to Wilms Tumor: Technique Without Cardiopulmonary Bypass

Wilms tumor is a frequent malignant neoplasia in pediatric population. Extension to the inferior vena cava is a complication that occurs in approximately 4%-15% of cases. Surgical techniques derived from the field of adult transplant surgery allow the resection of the tumor with its thrombus extension. In the case of a 6-year-old male patient with a stage III Wilms tumor that originated from the left renal vein, thrombectomy and left radical nephroureterectomy were accomplished without extracorporeal circulation. Surgical technique applied in adult transplant surgery for removal of advanced renal tumors, could be a safe and feasible technique in pediatric population.
