Most commonly, this is seen in renal cell carcinoma, but it can also occur with other primaries such as bronchogenic carcinoma. At the time of surgical stabilization of osseous metastases, excessive bleeding can be encountered as a result of this hypervascularity. This will often require transfusion of blood products, but in some cases death can result. The rationale of preoperative embolization is to decrease the vascularity of the metastatic lesion before stabilization and thus to decrease blood loss. The purpose of this article is to review the indications and results of preoperative embolization. © 2004 Lippincott Williams & Wilkins, Inc.
