目的　探讨用介入栓塞治疗下牙槽动脉闭合性损伤出血。方法　在X线机电视监视下选择造影后用明胶海绵颗粒栓塞下牙槽动脉。结果　 6例外伤后下牙槽动脉损伤破裂出血都得到满意控制。结论　介入栓塞治疗可以作为控制下牙槽动脉闭合性损伤出血的一种选择。 Objective To investigate the treatment of lower alveolar artery occlusion bleeding with interventional embolization. Methods Under the surveillance of X-ray TV, the inferior alveolar artery was embolized with gelatin sponge particles. Results 6 cases of inferior alveolar artery injury rupture hemorrhage have been satisfactorily controlled. Conclusion Interventional embolization can be used as an option to control the occlusive hemorrhage of the alveolar artery.
