摘要
目的 :探讨经导管动脉栓塞术在鼻咽血管纤维瘤摘除术前的临床应用价值。方法 :12例鼻咽血管纤维瘤 ,经股动脉行超选择插管造影 ,采用聚乙烯醇颗粒和 /或明胶海绵颗粒栓塞肿瘤供血动脉 ,全部患者于栓塞后 3～ 7d手术切除肿瘤。结果 :12例均见到明显的肿瘤染色 ,供血动脉丰富。颌上动脉栓塞 12例 ,同时栓塞咽升动脉 8例。所有病例均取得良好效果。结论 :本组资料表明超选择插管造影诊断、栓塞、治疗及栓塞颗粒大小是技术成功的主要条件。经导管动脉栓塞术在鼻咽血管纤维瘤摘除术前的应用是安全有效的。
Objective:To assess the value of transcatheter arterial embolization (TAE) in nasopharyngeal angio- fibroma before surgical operation.Methods:TAE was performed in 12 patients with nasopharyngeal angiofibroma.Emboli- zatoin was performed with polyvinyl alcohol particals and gelfoam (GF).All patients underwent surgery in 3 to 7 days after TAE.Results:During angiography,tumour staining was seen in 12 patients.Embolization of maxillary artery was performed in 12 cases and additional embolization of ascending pharyngeal artery in 8.Good results were achieved.Conclusion:Super- selective angiographic diagnosis and embolization with appropriate embolic particle size are important for successful treatment of nasopharyngeal angiofibroma.TAE is safe and effective in decreaing haemorrhage during surgical operation for nasopharyngeal angiofibroma.
