Abstract
Five patients underwent preoperative embolization of osseous metastases from renal cell carcinoma. The group consisted of 4 men and 1 woman who ranged in age from 46-79 yr. The lesions were located in the pubic ramus and acetabulum, proximal femur, femoral midshaft, proximal humerus and proximal tibia. All embolizations were performed within 24 h of surgery. The internal fixation and tumor curettage was accomplished with estimated perioperative blood loss ranging from 10-1250 ml. All patients had significant restoration of function following surgery. Preoperative embolization probably is an important and efficacious adjunct in the management of hypervascular renal cell osseous metastases.
