数字减影血管造影及介入栓塞术在口腔颌面部的应用

目的：探讨数字减影血管造影术（DSA）及选择性颈外动脉分支栓塞术在口腔颌面部肿瘤诊断和治疗的应用价值。方法：对22例颌面部肿瘤的DSA表现，栓塞、临床治疗治疗效果及并发症进行分析，结果：2例口腔腔大出血患者急诊行DSA及栓塞治疗后，立即停止活动性出血；1例上颌骨中心性血瘤行永久性栓塞，栓塞后3周面部膨畸形逐渐缩小，随访5例未见复发，栓塞后行手术切除的病,主中出血明显减少，瘤体完善切除，随访3年无复，结论：DSA及选择性颈外动脉分支栓塞技术是诊断和治疗颌面部肿瘤的行之有效的方法。

Digital subtraction angiography and selective external carotid embolization in the diagnosis and treatment of maxillofacial tumor

Objective:To study the feasibility of digital subtraction angiography(DSA) and selective external carotid embolization(SECE) in the diagnosis and treatment of maxillofacial tumor. Methods: DSA features, embolotherapy, clinical treatment and complications were investigated retrospectively in 22 cases diagnozed by means of DSA and treated with SECE. Results: After embolization, the bleeding was completely stopped in two cases with emergent hemorrhage, the tumor was shrunk in one case with central hemangioma in maxilla three weeks later and the bleeding in operation was reduced significantly. The tumor boundary was clear for tumorectomy in all the other cases. No recurrence was observed in 3-year-follow up. Conclusion:DSA and SECE are safe, optimal and effective in the treatment of maxillofacial tumour and hemorrhage.
