Abstract

Purpose

The purpose of this study is to evaluate the role of spinal angiography and arterial embolization in avoiding spinal cord ischemia in patients undergoing CT-guided alcohol injection of aggressive vertebral hemangiomas.

Methods

In this retrospective study, patients with vertebral hemangioma who underwent CT-guided direct alcohol injection between January 2007 and October 2018 were identified. Of 28 such patients, 26 had neurological deficits, and 2 had only back pain or radiculopathy. Direct alcohol injection without prior arterial embolization was done in 17 patients. Direct alcohol injection with prior arterial embolization was done in 11 patients. Clinical outcome was assessed immediately after the intervention and at follow-up.

Results

Three patients, who underwent alcohol injection without trans-arterial embolization, had worsening of neurological deficits in the post procedure period due to spinal cord ischemia. No complications related to spinal cord ischemia were noted in the embolization group. There was no significant difference in the outcomes between the two groups if the three patients with complications are excluded (p = 0.34).

Conclusion

While CT-guided direct alcohol injection is effective in the management of symptomatic and aggressive vertebral hemangiomas, spinal angiography and trans-arterial embolization of the blood supply to the vertebral body hemangioma, prior to the direct transpedicular alcohol embolization of the lesion, improves the safety of the procedure.
