超选择动脉栓塞术在鼻咽血管纤维瘤摘除术前的临床应用(英文)

目的探讨经导管超选择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叫血管纤维瘤摘除术前的临床应用是安全有效的。

Application of Superselective Artery Embolization in Nasopharyngeal Angiofibroma before Operation

Objective:To evaluate the clinical application of superselective transcatheter arterial emboliza- tion(TAE)in nasopharyngeal angiofibroma before operation.Methods:Superselective angiography was done via femoral.TAE with polyvinyl alcohol particles and/or gelfoam(GF)was performed in 12 patients with nasopharyngeal angiofibroma.All patients underwent surgical removal of devascularized tumors in 3 to 7 days after TAE.Results:During digital subtraction angiography,tumor staining was seen in 12 patients.Embolization of maxillary artery was performed in 12 cases and additional embolization of as- cending pharyngeal artery in 8 cases.Conclusion:Superselective angiographic diagnosis,embolization and appropriate embolic particle size are important for successful treatment of nasopharyngeal angiofi- broma.TAE is safe and effective in decreasing haemorrhage during surgical operation for nasopharyngeal angiofibroma.
