Vertebral hemangioma: retrograde embolization-stabilization with methyl methacrylate.

A new method, intraoperative retrograde embolization with a methyl methacrylate polymer injected into a vertebral hemangioma, is described. This method achieves complete intraoperative hemostasis and postoperative stabilization. No further stabilization procedures and radiation therapy are necessary. Preoperative selective angiography with embolization and consecutive laminectomy are required for this method.
