目的 减少脊柱肿瘤手术切除时的出血及因出血而造成的手术难度。方法 术前行选择性动脉栓塞 7例 ,未行动脉栓塞 9例作对照组 ,比较两组术中出血情况。结果 栓塞组患者术中出血明显少于对照组 ,平均出血量 (ml)栓塞组为 170 0± 10 0 ,对照组为 5 5 40± 381,P <0 0 1。结论 脊柱肿瘤切除前行选择性动脉栓塞 ,可减少术中出血量 ,有利于肿瘤与周围组织分离 ,肿瘤易完全切除
Objective To reduce bleeding during surgical resection of the spinal tumor and surgical difficulty due to bleeding. Methods Preoperative selective arterial embolization in 7 cases, no arterial embolism in 9 cases as control group, compared the two groups intraoperative bleeding. Results The number of hemorrhage in the embolization group was significantly less than that in the control group. The average amount of bleeding (ml) was 170 ± 10 in the embolization group and 55 ± 40 ± 381 in the control group, P <0.01. Conclusions Selective arterial embolization before resection of spinal tumors can reduce intraoperative blood loss, which is conducive to the separation of the tumor from the surrounding tissues and complete removal of the tumor
