脊柱、骨盆肿瘤的术前栓塞为外科手术解决术中失血提供了一种有价值的新方法。本组９例共接受术前栓塞１０次。病种有：软骨肉瘤、骨肉瘤、转移瘤、骨巨细胞瘤等。栓塞物质为明胶海绵和钢丝圈。以术中失血量作为疗效评价指标。栓塞后造影显示肿瘤染色均较栓塞前减少７５％以上。９例术中失血量在８００～２８００ｍｌ之间，平均术中失血１８００ｍｌ；未经栓塞治疗的病例术中失血多在３５００ｍｌ，多者可达１５０００ｍｌ，且手术成功率不高。本研究表明，脊柱、骨盆肿瘤术前栓塞能够有效地减少术中失血，提高手术治疗的成功率。
Preoperative embolization of spinal and pelvic tumors provides a valuable new method for surgical treatment of intraoperative blood loss. 9 patients in this group received a total of 10 preoperative embolizations. Diseases are: chondrosarcoma, osteosarcoma, metastases, giant cell tumor of bone and so on. Embolic materials are gelatin sponges and wire travellers. The intraoperative blood loss was used as an evaluation index. Embolization after embolization showed that the tumor staining was reduced by more than 75% compared with before embolization. The blood loss in 9 cases was between 800 and 2800ml. The average intraoperative blood loss was 1800ml. In the cases without embolization, the blood loss during operation was 3500ml, more than 15000ml, and the success rate was not high. This study shows that preoperative embolization of spinal and pelvic tumors can effectively reduce intraoperative blood loss and improve the success rate of surgical treatment.
