Abstract:
Objective To study the feasibility and safety of performing nephrectomy together with the removal of complicated inferior vena cava tumor thrombus under profound hypothermia and arrested circulation. Methods After made the median thoraco-abdominal incision, the exploration of the abdominal organs was done. The right kidney, inferior vena cava and renal pedicle were well exposed then. After the whole body heparinization, cannulas were put into ascending aorta, superior vena cava, aortic root and right superior pulmonary vein. The body temperature was reduced to 20℃ with cardiopulmonary bypass unit and the extracorporeal circulation was stopped then. Cut open the inferior vena cava at vena renalis dextra ingress and the F16 urinary catheter was inserted into atrum dextra through inferior vena cava and inflated. The tumor thrombus was pulled out and the right kidney was removed. The inferior vena cava incision was sutured to close and the extracorporeal circulation was resumed and patient was re-warmed.Results The operation time was 330 min and the extracorporeal circulation time was 90 min, while the profound hypothermia with circulatory arrest time was 20 min. The estimated blood loss during operation was 400 ml and 6 unit red cells and 600 ml blood plasm were transfused. The patient was awaked 2.5 h after the operation, food intake resumed 4 days after operation and the patient was discharged on day 10 post-operatively. After 6 months'follow-up, there were no local recurrence and metastasis occurred. Conclusion The technique of profound hypothermia and circulation arrest could improve the safety and efficacy in the treatment of renal cell carcinoma with suprahepatic (level Ⅲ) caval tumor thrombus.
