鼻咽部纤维血管瘤的动脉栓塞治疗

Intraarterial Embolization Treatment of Nasopharyngeal Fibroangioma

目的探讨选择性动脉栓塞治疗鼻咽部纤维血管瘤的安全性和有效性。方法采用股动脉路径,对8例鼻咽部纤维血管瘤患者进行双侧颈内外动脉造影;并采取超选择插管对鼻咽部纤维血管瘤的供血血管进行栓塞,供血动脉主要为颈外动脉系统,以其分支颌内动脉多见,部分有颈内动脉系统参与供血。结果8例患者于栓塞术后血管瘤体积明显缩小,其中5例于栓塞后2～3d行手术切除,术中出血量明显减少,肿瘤易于剥离。结论鼻咽部纤维血管瘤行动脉内栓塞,疗效肯定、安全可靠、并发症少,术前应用能减轻手术创伤、缩短手术时间、降低术后复发率。

Objective To investigate the safety and efficiency of the selective arterial embolization in the treatment of nasopharyngeal angiofibroma. Methods Bilateral carotid artery angiography were performed for demonstration of the arterial supply of tumor in 8 patients with nasopharyngeal fibroangioma. Then a superselective intra-arterial embolization was undertaken in supplying arteries of nasopharyngeal fibroangioma. The supplying arteries originated from maxillary artery branches of external carotid artery, and a part was concerned with internal carotid artery. Results The hemangioma volume of 8 patients was significantly reduced after embolization,five of these underwent operation on 2-3 days after embolization. The amount of bleeding in operation was thus reduced and the tumor was peel off easy. Conclusion The effect of intra-arterial embolization for nasopharyngeal angiofibroma is positive,safe and reliable with few complications. Preoperative application can reduce the surgical trauma, shorten the operation time and lower the postoperative recurrence rate.
