目的探讨骨盆肿瘤血供特点及术前导管栓塞的临床价值。方法术前对骨盆肿瘤的供血动脉进行导管栓塞,栓塞后进行手术治疗。结果血管造影显示丰富、多支动脉供血,一次均成功给予选择性栓塞。栓塞后造影见肿瘤供血动脉闭塞,染色消失,手术时肿瘤均全部切除。结论术前靶血管栓塞能降低手术的危险性,增加肿瘤切除率,同时可有效减少术中失血。 Objective To investigate the characteristics of pelvic tumor blood supply and the clinical value of preoperative catheter embolization. Methods Preoperative catheterization of the feeding artery for pelvic tumors, embolization after surgery. Results angiography showed rich, multi-artery blood supply, were successfully given a selective embolization. Tumor angiography showed embolization of blood supply artery occlusion, staining disappeared, the tumor were removed at surgery. Conclusion Preoperative target vessel embolization can reduce the risk of surgery and increase the rate of tumor resection, and can effectively reduce intraoperative blood loss.
