[Preoperative embolization of cervical bone metastasis with radio-controlled direct puncture].

Surgery of vertebral hypervascular metastasis can take advantage of preoperative embolization to make the surgical procedure easier to perform. Usually, embolizations are executed by vascular tract. We report a case of one cervical metastasis located in C4 for which embolization was executed with direct puncture of the vertebra. This method has the advantage to be feasible whatever tumoral vascularization, and more particularly in case of departure of radiculo-medullary artery or any other cephalic vessel from the tumoral site.
