Abstract

Operative management of patients presenting renal cell carcinoma's (RCC) with right atrial tumor thrombus extension is a technical challenge. It requires the use of cardiopulmonary bypass (CPB). The aim of this study was to report our early experience and to describe a simplified CPB technique. 5 consecutive patients underwent surgical resection by a joint cardiovascular and urological team. The ascending aorta was canulated. The venous drainage was achieved using a proximal canula inserted in the superior vena cava and a distal canula inserted in the IVC below the renal veins. Right atrium thrombus extension was extracted under normothermic CPB without cross clamping or cardioplegic arrest. A cavotomy was performed at the ostium of the renal vein and an endoluminal occlusion catheter was introduced. The thrombectomy and the radical nephrectomy were then performed. The occurrence of gaseous or tumor embolism, operative time, perioperative bleeding, and post-operative complications were assessed. Mean patients age was 62.9 years. Atrial and caval thrombectomy were achieved successfully in all patients. Mean operative time was 206 min. Mean CPB time was 62 min. Mean hospital stay was 18.8 days. One death occurred, due to respiratory failure. An asymptomatic early thrombosis of the IVC was diagnosed by CT scan in 1 patient. The four remaining patients were alive 6 months after the surgical procedure. Minimally invasive CPB technique can be used to treat intra atrial thrombus tumor extension arising from renal cell carcinoma. It can be performed safely with acceptable complications rate. © 2007 Surgical Associates Ltd.
