Preoperative elastoplasty of aggressive vertebral hemangiomas in elderly patients: a new strategy for reducing intraoperative bleeding and complications. EUROPEAN SPINE JOURNAL : OFFICIAL PUBLICATION OF THE EUROPEAN SPINE SOCIETY, THE EUROPEAN SPINAL DEFORMITY SOCIETY, AND THE EUROPEAN SECTION OF THE CERVICAL SPINE RESEARCH SOCIETY 2024; 33:1921-1929. [PMID: 38491218 DOI: 10.1007/s00586-024-08201-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/26/2023] [Revised: 02/18/2024] [Accepted: 02/21/2024] [Indexed: 03/18/2024]
Abstract
PURPOSE Preoperative 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. METHODS Three 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. RESULTS With 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. CONCLUSION When 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.

Abstract
BACKGROUND Aneurysmal bone cyst is composed of variable -sized cystic blood-filled spaces separated by connective tissue septae. First-line surgical resection of spinal aneurysmal bone cyst in a child with limited total blood volume can lead to massive intraoperative bleeding, thus limiting extent of resection. Our Centre's has good experience of using absolute alcohol as an effective immediate devascularizing agent during vertebral hemangioma surgery in children. MATERIAL AND METHODS We report the first case of pediatric lumbar primary aneurysmal bone cyst in which completely blood-less piecemeal total resection of the lesion was performed after intraoperative absolute alcohol intralesional sclerotherapy. RESULTS Completely blood-less piecemeal total resection of the lumbar aneurysmal bone cyst was performed after intraoperative absolute alcohol intralesional sclerotherapy. CONCLUSION Intraoperative absolute alcohol intralesional sclerotherapy is a very effective devascularizing adjunct for complete piecemeal resection of spinal aneurysmal bone cyst in children with limited blood volume.

Abstract
Vertebral hemangiomas of the spine are rare benign tumors. They occur primarily in the thoracic region and are often asymptomatic and found incidentally on radiological examination; however, some are symptomatic, aggressive, and gradually increase in size. Various therapeutic approaches have been proposed for their management. This study aimed to review the therapeutic management, focusing on ethanol sclerosis therapy. The PubMed database was searched from inception to January 2023 using the keywords "hemangioma", "spine OR vertebra", and "ethanol". Twenty studies were retrieved, including two letters. The first report of spinal therapy was published in 1994. Ethanol sclerosis therapy is effective in treating vertebral hemangiomas. It is performed independently or in combination with other techniques, such as vertebroplasty using cement and surgery. The therapy is performed under local or general anesthesia with fluoroscopic or computed tomography guidance. A total of 10-15 mL of ethanol is slowly injected via unilateral or bilateral pedicles. Complications of the therapy include hypotension and arrhythmia during the procedure, paralysis immediately after the procedure, and delayed compression fractures. This review could enable the refinement of knowledge regarding ethanol sclerosis therapy, which is a treatment option that could be adopted.

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.

Abstract
OBJECTIVE Vertebral hemangiomas are benign but highly vascular lesions and are one of the most common lesions of the vertebral column. Anterior soft-tissue compression of spinal cord due to vertebral body hemangioma is challenging to manage. Our objective was to assess long-term clinical and radiologic effects of direct transpedicular absolute alcohol embolization, laminectomy, and short-segment instrumented fusion on resolution of extraosseous epidural soft tissue and improvement in myelopathy in cases of vertebral hemangioma causing anterior soft-tissue compression. MATERIALS AND METHODS This was a retrospective analysis that included patients with single-level vertebral hemangioma with anterior intraspinal soft-tissue growth causing spinal cord compression and clinical features of myelopathy between June 2007 and June 2019 at authors' institute. Transpedicular vertebral body injection of absolute alcohol, laminectomy, and pedicle screw rod instrumentation was performed in all patients. Clinicoradiologic outcomes of surgery were noted. We proposed a grading system for the extent of anterior extraosseous epidural soft-tissue compression. RESULTS In total, 14 patients were included in study. Their mean age was 28.4 ± 14.4 years. Mean follow-up duration was 67.5 ± 36.2 months. All patients had preoperative radiologic grade 4 compression. Postoperative radiologic grading improved to grade 1 in 4 (28.6%), grade 2 in 8 (57.1%), and grade 3 in 2 (14.3%). All the patients improved neurologically after surgery. Eleven patients improved to American Spinal Injury Association (ASIA) grade E, 2 improved to ASIA D, and 1 improved to ASIA C at the last follow-up visit. CONCLUSIONS Vertebral hemangiomas with anterior extraosseous epidural extension causing spinal canal compromise and myelopathy can be managed with direct transpedicular ethanol embolization, laminectomy, and short-segment instrumented fusion with resolution of the extraosseous soft tissue and improvement in myelopathy. The procedure is relatively simple, cost effective, and has a good outcome.

Abstract
Background To investigate the imaging features of hemangiomas in long tabular bones for better diagnosis. Methods Twenty-four patients with long bone hemangiomas confirmed by pathology were enrolled. Nineteen patients had plain radiography, fourteen patients had computed tomography (CT) and eleven had magnetic resonance imaging (MRI). The hemangioma was divided into medullary [13], periosteal [6] and intracortical type [5]. Results Among 19 patients with plain radiography, eleven patients were medullary, three periosteal, and five intracortical. In the medullary type, the lesion was primarily osteolytic, including five cases with irregular and unclear rims and one lesion having osteosclerotic and unclear rims. In three patients with the periosteal type, the lesion had clear rims with involvement of the cortical bone in the form of bone defect, including two cases with local thickened bone periosteum and one case having expansile periosteum. Five intracortical hemangiomas had intracortical osteolytic lesions with clear margins. Among 14 patients with CT imaging, 8 cases were medullary, three periosteal, and three intracortical. Among 8 medullary hemangiomas, one had ground glass opacity, and seven had osteolytic, expansile lesions like soft tissue density with no calcification. In three periosteal cases, the lesion was osteolytic with thickened periosteum and narrowed medullary cavity. In three intracortical hemangiomas, the lesion was of even soft tissue density with no calcification. Among 11 patients with MRI imaging, seven were medullary, two periosteal, and two intracortical. Among 7 medullary lesions, six were of hypointense signal on T1WI and hyperintensesignal on T2 WI. In two periosteal cases, the periosteum was thickened, with one case being of equal signal, and the other having no signal. Two intracortical hemangiomas were both of slightly low signal on T1WI but hyperintense signal on T2WI. Conclusions The long bone hemangiomas had characteristic cystic honeycomb-like presentations in plain radiograph. CT and MRI imagings are helpful for diagnosis of hemangiomas in long bone.

Abstract
Background Elderly patients with vertebral hemangiomas are rare and might require surgery. Thus, the choice of surgery for these lesions remains controversial because of the rarity of these lesions. This study aimed to analyze the clinical efficacy of the intraoperative injection of absorbable gelatin sponge mixed with cement followed by spinal decompression to treat the elderly with typical vertebral hemangiomas. The risk factors for hemangioma recurrence were investigated through a literature review. Methods We retrospectively analyzed 13 patients with typical aggressive hemangiomas between January 2009 and January 2016. Of these patients, 7 were treated with spinal decompression combined with intraoperative vertebroplasty (Group A), and 6 patients were treated with decompression with intraoperative vertebroplasty and absorbable gelatin sponge (Group B). The general data and perioperative data of the patients were compared. Patients were followed up for at least 3 years, and postoperative complications and recurrence rates were recorded and compared. Results All patients had typical aggressive hemangiomas. The average age of all patients was 64.4 ± 3.3 years. The preoperative data did not differ significantly between the two groups (P > 0.05). The blood loss of groups A and B was 707.1 ± 109.7 ml and 416.7 ± 103.3 ml, respectively (P = 0.003) (P = 0.003), and the average surgery durations were 222 ± 47.8 min and 162 ± 30.2 min, respectively (P = 0.022). The average follow-up duration was 62 ± 19 months, and no cases of recurrence were found at the final follow-up assessment. Conclusions Multimodal treatment significantly alleviated the clinical symptoms of elderly patients with typical aggressive vertebral hemangiomas. Intraoperative absorbable gelatin sponge injection is a safe and effective way to reduce blood loss and surgery duration.

Abstract
OBJECTIVE Vertebral hemangiomas (VHs) are the most common incidental lesions of vertebral body, but they are very challenging to treat if they become symptomatic. Several treatments have been proposed but none was superior to others. The aim of this study is to analyze blood loss and long-term clinical and neurological results of aggressive VHs treated with arterial embolization the day before operation, followed by vertebroplasty, posterior decompression, and short segment stabilization. METHODS Ten patients (4 males and 6 females) were treated for aggressive VHs with polyvinyl alcohol microparticles embolization, posterior short segment stabilization, and poly methyl methacrylate. Clinical and neurological outcomes were assessed with visual analog, Nurick, and American Spinal Injury Association (ASIA) scales. RESULTS At last follow-up mean, visual analog scale was 1.8 ± 1.3, with a significant difference with preoperative values (P = 0.00018). Neurological deficits persisted in 4 patients (ASIA scale: C in 1 patient [10%], D in 3 patients [30%]), but they improved from baseline in all cases. Also, Nurick scale rating improved in all patients (0 in 3 patients [30%], 1 in 4 patients [40%], 2 in 2 patients [20%], and 3 in the last one [10%]). A statistically significant difference between pre- and postoperative values was observed for both scores (ASIA, P = 0.0102; Nurick, P = 0.026). Relapse of pathology was recorded in 2 patients. CONCLUSIONS Polyvinyl alcohol microparticles embolization, short segment fixation, and vertebroplasty is an effective treatment option for aggressive VHs, with a fast surgical time, poor blood loss, and improvement of preoperative clinical and neurological outcomes.
