摘　　要：目的 观察犬髂内动脉栓塞后侧支循环重建的时间，为骶骨肿瘤术前选择性靶动脉栓塞减少术中失血，提供最佳手术时机。方法 用直径为 200～ 400μ m明胶海绵颗粒对 10只犬双侧髂内动脉进行栓塞，分别于栓塞后第 12、 24、 48、 72、 108 h摄 DSA片，对髂内动脉侧支循环重建的情况进行对比观察。结果 栓塞后 12 h DSA显示有少数侧支循环重建，参与栓塞区供血， 24 h显示有较多侧支循环重建，参与栓塞区供血， 48 h DSA显示侧支循环数量成倍增加。结论 靶动脉栓塞后 24 h以内是治疗骶骨肿瘤的最佳手术时机。Objective To estimate the optimal period for the resection of sacral tumor after selective arterial embolization by observing the re establishment of the collateral circulation following embolization of the internal iliac arteries. Methods The bilateral internal iliac arteries were embolized with gelfoam particles in ten dogs. Then the re establishment of the collateral circulation was observed with DSA at different times (12, 24, 48, 72， 108 hours) after operation. Results A few branches of collateral circulation was observed 12 hours after embolization and more were observed 24 hours later; the collateral circulation was abundant 48 hours after embolization. Conclusion The optimal period for the operation of sacral tumor is 24 hours after arterial embolization.
