摘要
目的探讨鼻咽部纤维血管瘤术前超选择栓塞的临床价值。方法 14例经CT和CTA诊断并为手术病理证实的鼻咽部纤维血管瘤患者,术前全部行双侧颈内、外动脉血管造影。肿瘤均为颈外系统供血,术前使用300~510μm多聚乙烯醇颗粒（PVA）及明胶海绵条超选择性栓塞治疗,栓塞后1~3天行手术切除。结果 14例患者,其中颌内动脉分支供血9例,颌内动脉和咽升动脉分支供血5例。所有患者颈外动脉供血分支用Cobra导管超选择性栓塞,均获得成功。栓塞后,13例肿瘤染色完全消失,1例肿瘤染色大部分消失。无临床并发症出现。结论术前血管内超选择栓塞供血动脉是治疗鼻咽部纤维血管瘤一种安全、有效的辅助方法。
Objective To study the clinical value of preoperative superselective embolization of nasopharyngeal angiofibroma.Methods Fourteen patients with nasopharyngeal angiofibroma diagnosed by CT and CTA,and proved surgically and pathologically were included in this study.Angiography of bilateral external and internal carotid artery were performed in all cases.The external carotid arterial blood supply of tumors were superselectively embolized with 300-510 μm particles of polyvinyl alcohol（PVA） and gelform.Surgical resection was performed post-embolization within 1 to 3 days.Results The main feeding vessels of tumors were the internalmaxillary artery in 9 patients,the internalmaxillary artery and ascending pharyngeal artery in 5 patients.Preoperative endovascular embolization of the branches of external carotid artery with catheter was achieved in all patients.After embolization,tumor stains disappeared completely in 9 patients and partially in 5 patients.There was no complication.Conclusion Preoperative intravascular embolization of nasopharyngeal angiofibroma with catheter is a safe and effective method.
