目的回顾分析超选择胸腰动脉栓塞在椎体肿瘤切除术前应用的价值。方法胸11~12椎体2例,腰2~4椎体9例,超选择插管至相应动脉灌注化疗栓塞,24小时后行病椎肿瘤切除置换术。结果11例肿瘤均能较顺利地切除,术中平均出血360 ml。随访平均18个月,术前有腰背疼痛伴下肢痛者均有缓解,7例术后疼痛完全消失,4例胸腰背痛减轻、下肢痛消失;4例截瘫基本恢复正常,1例截瘫无改变。结论选择性腰动脉栓塞可有效减少术中出血,提高了手术成功率,降低手术危险性,为彻底切除肿瘤创造条件。
Objective To retrospectively analyze the value of superselective thoracic and lumbar artery embolization in the application of tumor resection. Methods Thoracic 11 ~ 12 vertebrae in 2 cases and 2 ~ 4 vertebral body in 9 cases were surgically selected and intubated to the corresponding arterial infusion chemoembolization. Twenty-four hours later, the resected and replaced vertebral tumors were treated. Results All 11 cases of tumors were able to be successfully resected. The mean intraoperative bleeding was 360 ml. All patients were followed up for an average of 18 months. Preoperative low back pain with lower extremity pain were relieved. Seven cases of postoperative pain disappeared completely. Four cases of thoracolumbar back pain and lower extremity pain disappeared. Four cases of paraplegia returned to normal and one case of paraplegia No change. Conclusion Selective lumbar arterial embolization can effectively reduce intraoperative bleeding, improve the success rate of surgery, reduce the risk of surgery, and create conditions for radical resection of the tumor.
