Abstract
Wilms’ tumor (WT) is the most common pediatric renal tumor that often spreads to inferior vena cava and sometimes up to right atrium (RA). We describe successful management of 3-year-old child diagnosed with WT having extension up to RA. He was operated under cardiopulmonary bypass and extubated on postoperative day 2 and discharged. Perioperative anesthesia concerns were shock from dynamic tricuspid valve obstruction, intraoperative massive blood loss, and a higher risk of pulmonary thromboembolism during tumor manipulation.
