Vertebral haemangiomas are usually asymptomatic and discovered fortuitously during imaging. A small proportion may develop variable degrees of pain and neurological deficit. We prospectively studied six patients who underwent eight surgical procedures on 11 vertebral bodies. There were 11 balloon kyphoplasties, six lumbar and five thoracic. The mean follow-up was 22.3 months (12 to 36). The indications for operation were pain in four patients, severe back pain with Frankel grade C paraplegia from cord compression caused by soft-tissue extension from a thoracic vertebral haemangioma in one patient, and acute bleeding causing Frankel grade B paraplegia from an asymptomatic vascular haemangioma in one patient. In four patients the exhibited aggressive vascular features, and two showed lipomatous, non-aggressive, characteristics. One patient who underwent a unilateral balloon kyphoplasty developed a recurrence of symptoms from the non-treated side of the vertebral body which was managed by a further similar procedure. Balloon kyphoplasty was carried out successfully and safely in all patients; four became asymptomatic and two showed considerable improvement. Neurological recovery occurred in all cases but bleeding was greater than normal. To avoid recurrence, complete obliteration of the lesion with bone cement is indicated. For acute bleeding balloon kyphoplasty should be combined with emergency decompressive laminectomy. For intraspinal extension with serious neurological deficit, a combination of balloon kyphoplasty with intralesional alcohol injection is effective.
椎体血管瘤通常无症状,多在影像学检查时偶然发现。一小部分可能会出现不同程度的疼痛和神经功能缺损。我们前瞻性地研究了6例患者,对11个椎体进行了8次手术。其中包括11次球囊后凸成形术,6次腰椎手术和5次胸椎手术。平均随访时间为22.3个月(12至36个月)。手术指征包括4例患者的疼痛,1例因胸椎椎体血管瘤软组织延伸导致脊髓受压引起Frankel C级截瘫的严重背痛,以及1例因无症状血管性血管瘤急性出血导致Frankel B级截瘫。4例患者表现出侵袭性血管特征,2例表现为脂肪瘤样、非侵袭性特征。1例接受单侧球囊后凸成形术的患者,椎体未治疗侧出现症状复发,通过再次进行类似手术得以处理。所有患者均成功、安全地进行了球囊后凸成形术;4例无症状,2例有明显改善。所有病例均有神经功能恢复,但出血较正常情况多。为避免复发,建议用骨水泥完全闭塞病变。对于急性出血,球囊后凸成形术应与急诊减压性椎板切除术联合应用。对于伴有严重神经功能缺损的椎管内延伸,球囊后凸成形术与病灶内酒精注射联合应用有效。
