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MRI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及椎动脉血管造影肿瘤颈外系统供血动脉术前使用100～300μm明胶海绵颗粒或聚乙烯醇(PVA)颗粒超选择性栓塞治疗,栓塞后1～3d行手术切除结果14例患者,颌内动脉分支供血9例,颌内动脉和咽升动脉分支供血4例,颌内动脉、咽升动脉和颈内动脉分支供血1例所有患者颈外动脉供血分支微导管超选择性栓塞均获得成功栓塞后,8例肿瘤染色完全消失,6例肿瘤染色大部分消失手术全切率92.8%(13/14),手术平均出血约420m,l手术时间平均150min所有患者栓塞后均未发生严重并发症结论使用微导管术前血管内超选择栓塞鼻咽部纤维血管瘤,是一种安全有效的辅助治疗方法
Objective To investigate the clinical value of preoperative superselective embolization in nasopharyngeal fibrohoma.Methods 14 cases of nasopharyngeal fibroadenoma diagnosed by CT and MRI and confirmed by surgery and pathology were treated with bilateral internal and external carotid artery and vertebral artery Angiography of the external tumor of the neck feeding artery preoperative use of 100 ~ 300μm gelatin sponge particles or polyvinyl alcohol (PVA) particles super selective embolization, 1-3 days after embolization of the results of surgical resection in 14 patients, the branch of the internal mammary artery blood supply 9 In 4 cases, the internal mammary artery and the branch of pharyngeal ascending artery were supplied with blood supply, the internal mammary artery, the ascending pharyngeal artery and the branch of the internal carotid artery were supplied with blood supply in 1 case. All the patients with external carotid artery branching microvascular catheter were successfully embolized and 8 cases Tumor staining completely disappeared, the majority of the 6 cases of tumor staining disappeared 92.8% (13/14), the average operation was about 420m, the average operation time was 150min. No serious complications occurred after embolization in all patients. Conclusion The use of microcatheter Pre-selective endovascular embolization of nasopharyngeal fibro-hemangioma is a safe and effective adjuvant therapy
