脊椎及椎旁肿瘤的术前栓塞治疗

Preoperative Endovascular Embolization of Vertebral and Para-vertebral Tumors

目的:探讨脊椎及椎旁肿瘤的术前栓塞对外科切除手术的辅助作用。材料和方法:对28例患者的脊椎及椎旁肿瘤使用PVA颗粒和(或)明胶海绵进行供血血管超选的介入栓塞治疗,然后在随后进行的肿瘤外科切除手术中记录手术出血量、肿瘤瘤体切除率。结果:28例患者栓塞后发现肿瘤血管及肿瘤染色大部闭塞,手术平均出血量1138ml,所有患者术后未出现严重的与栓塞治疗相关的脊髓损伤并发症。结论:术前脊柱肿瘤的血管内栓塞可以明显减少术中的出血量,提高肿瘤的彻底切除率,减少手术的并发症。

Purpose： To evaluate the safety and value of preoperative endovascular embolization of vertebral and para - vertebral tumors. Materials and Methods： The 28 patients with vertebral or para - vertebral tumors underwent DSA and gradually super selective endovascular embolization with PVA/ gelfoam before surgical resection. Results： The 28 cases were found tumors feed arteries occluded after embolization. They had their masses resected with significant reduction of blood loss （average 1138ml） with no serious complications of endovascular embolization at last.Conclusion： Preoperative embolization of vertebral/para - vertebral tumors is safe and reduce intraoperative blood loss significantly and is beneficial to rescet tumors.
