Solitary fibrous renal tumor with thrombus extension into the inferior vena cava and right atrium

Abstract

A solitary fibrous tumor of the kidney with thrombus extended into the inferior vena cava and right atrium is very rare. The current surgical approach is to combine intra-abdominal and cardiac surgery with cardiopulmonary bypass. We describe a rare case of renal solitary fibrous tumor extended to the inferior vena cava and right atrium, treated with urgent cardiac surgery using deep hypothermic circulatory arrest one month after an inappropriate right nephrectomy because of the development of cavo-atrial obstruction symptoms.

Preoperative stereotactic body radiotherapy combined with surgical treatment for renal cell carcinoma and inferior vena cava tumour thrombus: study protocol for a single-arm cohort trial

“…The clinical significances of this trial are as follows: (1) For Mayo III–IV classification, it may reduce the difficulty of operation, blood loss, blood transfusion rate and perioperative complications. Some cases of Mayo IV grade may require cardiac surgery interventions for complete surgical treatment, 38 and preoperative radiotherapy may create the possibility of not needing cardiac surgery; (2) For Mayo II–IV classification, preoperative radiotherapy+surgery may be better than surgery alone, which prolongs survival and reduces recurrence rate and (3) When the tumour thrombus invades the inferior vena cava wall in a wide range, preoperative radiotherapy can be used to preserve the inferior vena cava vessel wall.…”
