Outcome of dorsolumbar vertebral hemangiomas presenting with neuraxial compression.

Abstract

Hemangiomas are benign vascular tumors associated with proliferation of blood vessels in bone or soft tissue and they are usually incidental findings in vertebrae. When symptomatic, they present with features of radiculopathy, myelopathy, or vertebral fractures. Treatment options are varied, include sole embolization, embolization combined with surgical excision, surgical excision alone, percutaneous ablation, and radiotherapy. We hereby describe a series of seven cases of symptomatic vertebral hemangiomas operated from 2006 to 2009. Their clinical and radiological profile and outcome have been described. All patients were subjected to surgical excision followed by instrumentation. Outcome was assessed at a followup of 2 years following surgery with Frankel grading system. Seven patients (five females and two males) were included in the study. The mean age was 33.85 years with the mean duration of symptoms of 12 months. All seven cases were symptomatic vertebral hemangiomas with cord compression and underwent surgical excision. Preoperatively, patients with poor Frankel grade such as A and B improved postoperatively to C, D, or E. Surgical excision of these lesions is difficult due to the tremendous amount of intraoperative bleeding. During surgery, brisk bleeding is usually encountered, but can be brought under control with adequate preoperative preparation and expertize. Preoperative embolization may help to reduce the bleeding, but at times it may be difficult to do if vertebrae are replaced by a solid hard mass. In spite of the risks associated with surgery, it still is the treatment of choice as a single intervention, especially in aggressive vertebral hemangiomas.
