目的 :脊椎肿瘤以手术切除为首选方案 ,术中大出血 ,往往不能全部切除肿瘤 ,且术后死亡、并发症的发生率较高。术前选择性靶动脉栓塞为解决这一难题提供了一种有价值的新方法。方法 :用seldinger技术经股动脉选择性血管造影 ,逐支超选择性栓塞肿瘤靶动脉。结果 :成功的术前栓塞病例术中失血量明显减少 ,为 40 0～ 3 0 0 0ml。结论 :脊柱肿瘤术前选择性靶动脉栓塞可明显减少术中出血。本文对栓塞的手术时机选择、栓塞后并发症的预防和处理分别进行讨论。
Objective : Surgical resection of spinal tumors is the first choice. Intraoperative hemorrhage can not always completely remove the tumor. The incidence of postoperative death and complications is high. Preoperative selective target arterial embolization provides a valuable new method to solve this problem. METHODS: Selective angiography of the femoral artery using seldinger technique was performed to selectively embolize tumor target artery. RESULTS: Successful preoperative embolization showed a significant decrease in blood loss during the operation, ranging from 400 to 3000 ml. Conclusion: Selective target arterial embolization before spinal tumor can significantly reduce intraoperative blood loss. This article discusses the timing of embolization surgery, the prevention and management of post-embolization complications.
