目的：了解鼻咽部纤维血管瘤的血供情况及术前栓塞对术中出血、手术全切率和术后疗效的影响。材料与方法：对１６ 例鼻咽部纤维血管瘤患者进行数字减影血管造影，并经５Ｆ 造影导管用直径２５０ ～１０００μｍＩｖａｌｏｎ 栓塞肿瘤供血动脉。结果：鼻咽部纤维血管瘤主要由同侧的颌内动脉供血，同侧颈内动脉参与供血的占６／１６ ，对侧颈外动脉参与供血的占５／１６ 。供血动脉栓塞后肿瘤染色大部分消失，术中出血明显减少。结论：鼻咽纤维血管瘤的术前栓塞有助于减少术中出血，增加手术安全性，提高手术全切率和术后疗效。
Objective: To understand the blood supply of nasopharyngeal fibro-hemangioma and the effect of preoperative embolization on the intraoperative bleeding, the total surgical incision rate and the postoperative curative effect. MATERIALS AND METHODS: Digital subtraction angiography was performed in 16 patients with nasopharyngeal fibrovascular tumors and embolization of the tumor feeding artery with 5valve angiography catheter with a diameter of 250 ~ 1000μm. Results: Nasopharyngeal fibro-hemangioma was mainly supplied by ipsilateral intra-maxillary artery, ipsilateral internal carotid artery involved in blood supply 6/16, contralateral external carotid artery involved in blood supply 5/16. Most of the tumor staining disappeared after the arterial embolization of the artery, and the intraoperative bleeding was significantly reduced. Conclusion: Preoperative embolization of nasopharyngeal hemangioma can help to reduce the intraoperative bleeding, increase the safety of operation, and improve the operation rate and postoperative curative effect.
