目的： 探讨数字减影血管造影(DSA)在耳鼻咽喉科的应用价值。方法： 对10例耳鼻咽喉科疾病患者进行DSA检查和栓塞治疗。结果： 本组4例鼻咽纤维血管瘤手术前选择性地栓塞瘤体内动脉血管，手术出血量明显减少；3例耳廓及头颈巨大蔓状血管瘤中2例姑息对症性栓塞后，耳廓变小、，变硬，溃破出血停止，但其中1例栓塞后并发一侧周围性面瘫，另1例术前栓塞配合手术，减少了术中出血；1例左鼻腔血管瘤栓塞治疗24 h后，并发左眼鼻侧下方视野缺损；2例难治性鼻出血，栓塞治疗后鼻出血得到控制。结论 ：DSA选择性动脉栓塞配合手术治疗耳鼻咽喉科血管性肿瘤、血管畸形，可明显减少术中出血，对控制严重鼻出血是一种有效的新方法，但应重视并发症的发生。
Objective: To investigate the value of digital subtraction angiography (DSA) in otolaryngology. Methods: Ten patients with otorhinolaryngology were treated with DSA and embolization. Results: In this study, 4 patients with nasopharyngeal fibroadenoma were selectively embolized with arterial blood vessels before operation, and the amount of bleeding during operation was significantly reduced. Two cases of pyloric and giant-scale vascular hemangioma were treated with palliative embolization Smaller, harder, ulcerated hemorrhage stopped, but one case complicated by peripheral facial paralysis after embolization and the other one with preoperative embolization surgery to reduce intraoperative bleeding; 1 case of left nasal hemangioma embolization for 24 h After the concomitant left eye nasal lateral visual field defect; 2 cases of intractable epistaxis, epistaxis after embolization was controlled. CONCLUSIONS: Selective arterial embolization combined with surgery in the treatment of otolaryngology vascular tumors and vascular malformations can significantly reduce intraoperative bleeding, which is an effective new method for the management of severe epistaxis. However, complications should be emphasized.
