骶骨肿瘤术前栓塞的临床应用研究

目的：探讨经导管行肿瘤供血动脉术前栓塞在手术切除骶骨肿瘤中的价值和作用。方法：11例骶骨肿瘤患者进行数字减影血管造影明确靶血管情况后，采用明胶海绵结合弹簧圈栓塞靶血管，并于栓塞后1-3天行骶骨肿瘤切除。结果：11例肿瘤靶血管栓塞后，肿瘤染色基本消失，手术切除顺利，术中出血明显减少，平均出血量为750ml。11例平均随访12个月，未见局部复发。结论：骶骨肿瘤的术前动脉栓塞能有效降低术中出血，减少并发症的发生。增加了肿瘤切除率和彻底切除的可能性，是十分安全有效的治疗方法。

The clinical appilication study of preoperative arterial embolization before surgical treatment of sacral tumors

Objective：To study and evaluate the efficacy of preoperative transcatheter arterial embolization in the treatment of sacral tumor. Methods：Eleven eases of sacral tumor were examed with DSA to make sum the conditions of target arter embolized with gelfoamor stainless coils 1 to 3 days before operation. Results： Tremendous reduction of blood loss during surgery was found in all eases, the blood loss was 7.50 ml. Eleven eases were followed up for a period of average of 12 months. No recurrence of the sacral tumors was seen. Conelusion： Preoperative arterial embolization is effective in decreasing intraoperative blood loss and can lead to safe results.
