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咽血管纤维瘤摘除术前的临床应用是安全有效的。
Objective To investigate the clinical value of transcatheter superselective arterial embolization before nasopharyngeal angiofibroma resection. Methods Twelve patients with nasopharyngeal angiofibroma underwent superselective intubation through the femoral artery. Polyvinyl alcohol granules and / or gelatin sponge particles were used to embolize the feeding artery of the tumor. All patients underwent surgical resection 3-7 days after embolization. Results All the 12 cases showed obvious tumor staining and rich donor arteries. Maxillary artery embolism in 12 cases, while embolization of pharyngeal ascending aorta in 8 cases. All cases achieved good results. Conclusion The data in this group show that the diagnosis, embolization, treatment and embolization particle size of super selective catheterization are the main conditions for successful technology. Transcatheter arterial embolization in nasopharyngeal angiofibroma surgery before the clinical application is safe and effective.
