12例鼻咽纤维血管瘤的术前栓塞治疗临床分析

目的对鼻咽纤维血管瘤术前栓塞的疗效及并发症进行评价。方法回顾性分析2002年11月至2006年11月以来经手术及病理证实的鼻咽纤维血管瘤患者12例，12例鼻咽纤维血管瘤手术前1～3d行超选择供血动脉栓塞，详细观察栓塞后毒副作用及并发症，并记录手术时出血量。结果血管造影可清晰显示肿瘤病变范围及供血情况，12例患者中一侧颌内动脉供血8例，合并咽升动脉供血4例。7例完全栓塞，5例仅部分栓塞。毒副作用为栓塞侧面部疼痛4例，无严重并发症发生。所有病变均完整切除。术中平均出血量为470ml。结论鼻咽纤维血管瘤术前栓塞能减少外科术中出血并提高肿瘤切除率。

Pre-surgical embolization of 12 Cases With nasopharyngeal angiofibroma

Objective To invest the efficacy and complication of pre-samcal embolization of nasopharyngeal angiofibroma.Methods 12 cases with nasopharyngeal angiofibroma underwent superselective feeding arteries emboilization 1-3 days before sugery.The side effect and complication were observed.The intraoperative blood loss was recorded.Results 8 cases of nasopharyngeal angiofibroma were supplied by single-side internal maxillary artery,and 4 cases combined with ascending pharyngeal artery.The side effect included 5cases of face ache.No serious complication happened after embolization.AIIlesions were radical removed.The average intraoperative blood loss was 470 ml.Conclusion The pre-surgical embolization of nasopharyngeal angiofibroma can reduce the intraoperative blood loss and increase radical resected rate.
