Therapeutic strategies of bone metastases management in interventional radiology

A wide range of interventional radiology methods is currently available for the management of bone metastasis disease. Indications should be discussed in pluridisciplinary staff, depending of therapeutic intent (curative or palliative), risk of fracture, and general status of the patient. The aim of this article is to present these techniques. Cementoplasty, defined by percutaneous injection of polymethylmethacrylate into bone metastases, is used to relieve pain and prevent pathological fractures. Thermal ablation techniques are applied to achieve partial or complete destruction of bone lesions, by increasing (radiofrequency and micro-waves) or decreasing (cryoablation) intratumoral temperature. Arterial embolization and chemoembolization are used to reduce blood supply of bone tumors, in order to manage pain or before orthopedic surgery of hypervascular lesions. For the most complexes cases, combined treatment can be proposed. (C) 2017 Elsevier Masson SAS. All rights reserved.
