PurposePreoperative elastoplasty could be an alternative strategy for treating aggressive vertebral hemangiomas (VHs) in frail patients needing for spinal cord decompression, combining the advantages of embolization and vertebroplasty.MethodsThree elderly patients with spinal cord compression from thoracic aggressive VHs underwent XperCT-guided percutaneous injection of silicone (VK100), filling the whole affected vertebra, followed by a decompressive laminectomy. At 12-months follow-up no recurrences, vertebral collapse or segmental kyphosis were noted at the CT scans, with patients reporting an improvement of preoperative neurological deficits, VAS and Smiley-Webster pain scale (SWPS) parameters.ResultsWith its elastic modulus, non-exothermic hardening, and lower viscosity than PMMA, VK100 allowed a preoperative augmentation of the affected vertebral body, pedicles, and laminae without complications, with a controlled silicone delivery even in part of VH's epidural components thanks to XperCT-guidance.ConclusionWhen facing highly bony erosive VH encroaching the spinal canal, VK100 combines the advantages of embolization and vertebroplasty especially in elderly patients, permeating the whole VH's angioarchitecture, significantly reducing tumor.© 2024.
