Percutaneous Cement Vertebroplasty in the Treatment of Symptomatic Vertebral Hemangiomas

摘要

Vertebral hemangiomas are benign tumors with a rich vasculature. Symptoms may vary from simple vertebral pain, sometimes resistant to conservative medical treatment, to progressive neurological deficit. Surgery or radiotherapy have been the treatment of choice for several years, but they were worsened by intraoperative and postoperative hemorrhagic complications related to the rich vascularization that characterize these kinds of lesions, often preceded by a preoperative embolization in the acute setting. Recently, a percutaneous, minimally invasive technique of vertebroplasty has been introduced into clinical practice as an alternative to traditional surgical and radiotherapy treatment of symptomatic vertebral hemangiomas with or without features of aggressiveness at imaging studies.
