目的 :评价骶骨肿瘤进行术前局部动脉内灌注化疗栓塞的价值。方法 :2 9例骶骨肿瘤患者行术前化疗栓塞 ,观察其临床改善情况与病理结果。结果 :血管造影可清楚显示肿瘤的大小及血供特点 ,术中出血大大减少 ,治疗后大部分患者临床症状改善 ,手术及病理证实 :肿瘤均有不同程度的坏死、液化和囊性变 ,假包膜形成。结论 :骶骨肿瘤术前化疗栓塞的效果明显 ,其作用在于 :使肿瘤坏死缩小 ,分界变清 ,减少肿瘤血供 ,有利于完整切除 ,提高手术成功率。术前化疗栓塞是骶骨肿瘤术前有效的辅助性治疗手段。
Objective: To evaluate the value of preoperative local intra-arterial chemoembolization in sacral tumors. Methods: Twenty-nine patients with sacral tumor underwent preoperative chemoembolization. The clinical improvement and pathological findings were observed. Results: Angiography clearly showed the size of the tumor and the characteristics of blood supply. The bleeding during operation was greatly reduced. The clinical symptoms of most patients were improved after operation. Surgical and pathological findings showed that the tumors all had varying degrees of necrosis, liquefaction and cystic degeneration, Envelope formation. Conclusion: The effect of preoperative chemoembolization of sacral tumor is obvious. Its role is to reduce tumor necrosis, clear the boundaries and reduce the blood supply of the tumor, which is in favor of complete resection and improve the success rate of operation. Preoperative chemoembolization is an effective preoperative adjunctive treatment of sacral tumors.
