Almost half of all cases have involvement of the inferior vena cava, which must be addressed at the time of surgical excision. Further extension into the right atrium may pose an immediate vital risk and necessitates special operative techniques that employ cardiopulmonary bypass. Case Report: We report the case of a child with a left Wilms’ tumor with inferior caval and right atrial involvement, which led to significant hemodynamic compromise and urgent surgery. A left nephrectomy and cavoatrial thrombectomy were performed via a sterno-laparotomy. Our strategy employed moderate hypothermic circulatory arrest at 26°C and antegrade cerebral perfusion in order to improve visualization and ensure complete thrombectomy and protection of the abdominal organs. Conclusion: This case emphasizes the advantages of moderate hypothermic circulatory arrest compared to deep hypothermic circulatory arrest and normothemic cardiopulmonary bypass. ER -
