[Perioperative management of a patient with bilateral renal cell cancer and large vena caval tumor thrombosis].

Von Hippel-Lindau disease is a kind of rare autosomal dominant hereditary disease characterized with many kinds of tumor or cystic lesion. In this 30 year old woman, vena caval tumor thrombi from retroperitoneal malignancies caused by renal cell cancer extended into the right atrium. She was scheduled to undergo bilateral radical nephrectomy and removal of vena caval thrombi under continuous hemodiafiltration (CHDF) and extracorporeal circulation. CHDF and Biomedics Pump were on stand-by during the operation. Radical left nephrectomy was performed. In the right kidney, however only the tumor could be removed and other part of the right kidney remained untouched. Therefore, CHDF was not used because urine volume and electrolyte balance were maintained with furosemide administration. The change of blood pressure caused by inferior vena caval clamping at just below the renal vein was not so great that the operation was performed without extracorporeal circulation. Total blood loss was 12,000 ml and careful management of water balance was necessary. She did not need any hemodialysis after the surgery.
