Background ContextAggressive (Enneking stage 3, S3) vertebral hemangiomas (VHs) are rare, which might require surgery. However, the choice of surgery for S3 VHs remains controversial because of the rarity of these lesions.PurposeWe reported our experience of treating S3 VHs, and evaluated the effectiveness and safety of intraoperative vertebroplasty during decompression surgery for S3 VHs.Study DesignThis is a retrospective study.Patient SampleThirty-nine patients with a definitive pathologic diagnosis of aggressive VHs who underwent primary decompression surgery in our department were included in this study.Outcome MeasuresBasic data such as surgical procedure, surgical duration, estimated blood loss during surgery, and pathology were collected. The modified Frankel grade was used to evaluate neurologic function. Enneking staging was based on radiological findings.MethodsWe retrospectively examined aggressive VHs with neurologic deficits. Surgery was indicated if the neurologic deficit was severe or developed quickly or if radiotherapy was ineffective. Decompression surgery was performed. Intraoperative vertebroplasty during posterior decompression has been used since 2009. If contrast-enhanced computed tomography (CT) revealed a residual lesion, we recommended adjuvant radiotherapy with 40-50 Gy to prevent recurrence. Patients' basic and surgical information was collected. The minimum follow-up duration was 18 months. This study was partially funded by Peking University Third Hospital, Grant no. Y71508-01.ResultsAverage age of the 39 patients with S3 VHs who underwent primary decompression surgery was 46.2 (range, 10-69) years. All patients had neurologic deficits caused by aggressive VHs. Aggressive VH lesions were located in the cervical, thoracic, and lumbar spine in 2, 32, and 5 patients, respectively. The decompression-alone group had 17 patients, and the decompression plus intraoperative vertebroplasty group had 22. There were no statistically significant intergroup differences in preoperative information (p>.05). The average estimated blood losses were 1,764.7 mL (range, 500-4,000 mL) and 1,068.2 mL (range, 300-3,000 mL) in the decompression-alone group and decompression plus vertebroplasty group, respectively (p=.017). One patient who underwent primary decompression alone without adjuvant radiotherapy experienced recurrence after the first decompression. The average follow-up was 50.2 (range, 18-134) months, and no cases of recurrence were observed at the last follow-up.ConclusionsOur results suggest that posterior decompression effectively provides symptom relief in patients with aggressive (S3) VHs with severe spinal cord compression. Intraoperative vertebroplasty is a safe and effective method for minimizing blood loss during surgery, whereas adjuvant radiotherapy or vertebroplasty helps in minimizing recurrence after decompression.Copyright © 2017 Elsevier Inc.
