The risk of a serious complication after tumor embolization is low. Serious complications would include nerve damage, tissue damage, stroke, or death. When the following complications and corresponding thresholds are exceeded, a review willshould be conducted. Efficacy A review of the literature supports the benefits of embolization to facilitate the surgical resection of vascular tumors by reducing intraoperative blood loss. The indictors of efficacy are technical and clinical success.
Technical success is defined as occlusion of the targeted vessels.
Clinical success is a decrease in the expected blood loss during surgery, facilitating tumor removal and reducing surgical complication, or palliation of the symptoms described above. 50 References Bibliography 1.
