摘要
目的 探讨选择性鼻咽纤维血管瘤供血动脉术前栓塞的应用价值。方法 对 15例鼻咽纤维血管瘤行数字减影血管造影 (DSA)检查和栓塞治疗。供血动脉主要为颈外动脉的颌内动脉和 (或 )咽升动脉 ,栓塞材料用明胶海绵。结果 15例在选择性颈外动脉栓塞后行手术治疗 ,13例术中出血量明显减少 ,2例由颈外动脉 ,颈内动脉系统同时供血 ,仅选择性颈外动脉栓塞 ,术中出血量较多。栓塞后2～ 5d手术最为理想。结论 鼻咽纤维血管瘤供血动脉术前栓塞是临床有效的治疗方法之一。
Objective To study the practical value of preoperative selective intra-arterial embolization in the surgical treatment of nasopharyngeal fibroangioma. Methods Digital subtraction angiogrophy(DSA) and selective arterial embolization were carried out in 15 cases of nasopharyngeal fibroangioma. The supplying arteries originated from the maxillary and the pharyngeal ascending branches arising from external carotid artery were embolized with gelatin sponge. Results 15 cases underwent operation after selective embolization of blood supplying arteries and the amount of bleeding in operation was thus reduced greatly in 13 cases, while the blood loss during the surgery of another 2 cases was still considerable because both external carotid artery and internal carotid artery supplied the tumor with only embolization of the external carotid artery. Optimum time for the operation was taken on 2-5 days after the embolization. Conclusions Preoperative intra-arteral embolization for nasopharyngeal fibroangioma is a valuable method of choice for the clinical treatment.
