Vertebral hemangioma late results of retrograde embolization--stabilization with methyl methacrylate in two cases.

In two cases of hemangioma of the D7 and L1 vertebral bodies intraoperative posterior filling of the angioma was described. The technique allowed a conveniently bloodless operation, which resulted in stabilization. No other stabilization was necessary. Six months after the procedure an increase of vertebral body density was seen radiologically.
